04B0	48	Area reserved by FSUIPC. (See details for user accessible parts earlier in this document). [FS2000 & CFS2 only]. The more useful ones follow:
04B4	2	>fs2k adventure weather: This provides the temperature_surface_alt in metres. This is used to provide the METAR reporting station altitude so that the cloud bases can be converted to AGL.
04BA	2	>fs2k adventure weather: This provides the wind_surf_turb which is used to provide the surface wind’s upper gust speed in knots, with zero indicating no gusts.
04BC	2	>fs2k adventure weather: This provides the barometric_drift variable, which is used to provide the difference between the current aircraft position QNH (which may be in transition), and the METAR reported QNH as set by the weather control program. Adding this ‘drift’ value to the pressure will give the correct value for ATIS reports
04C0	2	>fs2k adventure weather: This provides the fsuipc_visibility in statute miles * 100

04CE	1	>fs2k adventure weather: This provides the cloud_low_cover 0–8
04CF	1	>fs2k adventure weather: This provides the cloud_high_cover 0–8

04D4	2	Dew point control: degrees C * 256. Sets surface layer dewpoint only, FSUIPC does rest. Write 0x8000 to release control back to FS2k/CFS2.
04D8	2	Surface layer wind speed, in knots (FS2k/CFS2). This may be different to the current wind speed at the aircraft—see offset 0E90. This also provides wind_surf_vel for FS2k Adventures.

04E0	88	Area reserved for Project Magenta
0560	8	Latitude of aircraft in FS units. To convert to Degrees: If your compiler supports long long (64-bit) integers then use such a variable to simply copy this 64-bit value into a double floating point variable and multiply by 90.0/(10001750.0 * 65536.0 * 65536.0). Otherwise you will have to handle the high 32-bits and the low 32-bits separately, combining them into one double floating point value (say dHi). To do, copy the high part (the 32-bit int at 0564) to one double and the low part (the 32-bit unsigned int at 0560) to another (say dLo). Remember that the low part is only part of a bigger number, so doesn’t have a sign of its own. Divide dLo by (65536.0 * 65536.0) to give it its proper magnitude compared to the high part, then either add it to or subtract it from dHi according to whether dHi is positive or negative. This preserves the integrity of the original positive or negative number. Finally multiply the result by 90.0/10001750.0 to get degrees. Either way, a negative result is South, positive North. [Can be written to move aircraft: in FS2002 only in slew or pause states]
0568	8	Longitude of aircraft in FS format. To convert to Degrees: If your compiler supports long long (64-bit) integers then use such a variable to simply copy this 64-bit value into a double floating point variable and multiply by 360.0/(65536.0 * 65536.0 * 65536.0 * 65536.0). Otherwise you will have to handle the high 32-bits and the low 32-bits separately, combining them into one double floating point value (say dHi). To do, copy the high part (the 32-bit int at 056C) to one double and the low part (the 32-bit unsigned int at 0568) to another (say dLo). Remember that the low part is only part of a bigger number, so doesn’t have a sign of its own. Divide dLo by (65536.0 * 65536.0) to give it its proper magnitude compared to the high part, then either add it to or subtract it from dHi according to whether dHi is positive or negative. This preserves the integrity of the original positive or negative number. Finally multiply the result by 360.0/(65536.0 * 65536.0) to get degrees. Either way, a negative result is West, positive East. If you did it all unsigned then values over 180.0 represent West longitudes of (360.0 – the value). [Can be written to move aircraft: in FS2002 only in slew or pause states]
0570	8	Altitude, in metres and fractional metres. The units are in the high 32-bit integer (at 0574) and the fractional part is in the low 32-bit integer (at 0570). [Can be written to move aircraft: in FS2002 only in slew or pause states]

05E6	2	Slew yaw rate: 0=heading constant, –ve = right, +ve=left, rate is such that 24 gives a complete 360 turn in about one minute.
05E8	2	Slew vertical rate: 16384=no change, 16385–32767 increasing rate down, 16383–0 increasing rate up. One keypress on Q (up) or A (down) makes a change of 512 units.

0890	2	Engine 1 Mixture lever, 0 – 16384
0892	2	Engine 1 Starter switch position (Magnetos), Jet/turbojet: 0=Off, 1=Start, 2=Gen Prop: 0=Off, 1=right, 2=Left, 3=Both, 4=Start Notes (for FS2K/CFS2): + Don’t forget to switch fuel on to start (mixture to max). list: Ignore">+ For FS2k type starting you need to set the ‘Start’ value here and monitor the combustion flag (below). When that is set, change the starter switch to another position (Both or Gen). FS98 models start immediately but you should still adopt the same procedure. list: Ignore">+ The Engine addressed by writes to this and the equivalent Engine 2–4 offsets will become selected (see 0888 above). It needs to stay selected during engine start, which means you can only start engines in sequence, not together. The original selection is restored automatically, however—but only when the starter is ‘released’ by writing a non-start value here. list: Ignore">+ FS98 prop planes transposed to FS2000 have misbehaving Magneto/Starter switch controls (whether FSUIPC is installed or not). You can start engines okay, but don’t expect to be able to select the Magnetos reliably.
0894	2	Engine 1 combustion flag (TRUE if engine firing)
0896	2	Engine 1 Jet N2 as 0 – 16384 (100%). This also appears to be the Turbine RPM % for proper helo models.
0898	2	Engine 1 Jet N1 as 0 – 16384 (100%), or Prop RPM (derive RPM by multiplying this value by the RPM Scaler (see 08C8) and dividing by 65536). Note that Prop RPM is signed and negative for counter-rotating propellers.
08A0	2	Engine 1 Fuel Flow PPH SSL (pounds per hour, standardised to sea level). Don’t know units, but it seems to match some gauges if divided by 128. Not maintained in all cases.

08BC	2	Engine 1 Pressure Ratio (where calculated): 16384 = 1.60
08BE	2	Engine 1 EGT, 16384 = 860 C. [Note that for Props this value is not actually correct. For FS2004 at least you will get the correct value from 3B70. In FS2004 the value here has been derived by FSUIPC to be compatible with FS2002 et cetera]
08C0	2	Engine 1 Manifold Pressure: Inches Hg * 1024
08C8	2	Engine 1 RPM Scaler: For Props, use this to calculate RPM – see offset 0898
08D0	4	Engine 1 Oil Quantity: 16384 = 100% On FS2000 FSUIPC usually has to derive this from a leakage value as it isn’t provided directly.
08D4	4	Engine 1 Vibration: 16384 = 5.0. This is a relative measure of amplitude from the sensors on the engine which when too high is an indication of a problem. The value at which you should be concerned varies according to aircraft and engine.

08DC	4	Engine 1 Hydraulic quantity: 16384 = 100%

0BDC	4	Flaps control, 0=up, 16383=full. The “notches” for different aircraft are spaced equally across this range: calculate the increment by 16383/(number of positions-1), ignoring fractions. See also offset 3BFA below. N.B. Do not expect to read this and see 100% accurate values. For example, 3x2047=6141 for the 3^rd dTtente up. But FS2000, at least, stores the flaps lever position in the FLT file as a % of 16384, and the percentage is stored to two decimal places. 6141 gets saved as 37.48% which converts back to 6140.7232 and this gets truncated here as 6140. However, 6140/2047 = 2.9995 which is as close as you need. Just round if you are using integers.
0BE0	4	Flaps position indicator (left). Note that in FS2002 and FS2004 this gives the correct proportional amount, with 16383=full deflection. It doesn’t correspond to the equally spaced notches used for the control lever. If you know the maximum deflection angle you can derive the current angle by ((max * position indicator) / 16383). Also, in FS2002 and FS2004 this only gives the inboard trailing edge flaps. Please see offsets 30E0–30FF for greater details where needed.

1400	48 x n	A set of Payload Station data, 48 bytes for each payload station (the count is in 13FC above). [FS2004 only]. Each 48 byte entry contains: double weight (lbs) double lateral distance from datum (feet) double vertical distance from datum (feet) double longitudinal distance from datum (feet) char Name[16]; // 16 char name, including 0 at end There’s room for up to 61 such stations here. If there are more you can’t access them this way. These loadings can be changed, and this does have some effect, but such changes are not being promulgated to the overall weights (offsets 30C0, 30C8, 3BFC) nor balance (2EF8), and it looks like they have to refreshed, as FS overrides them from time to time. It has also been reported that FS can crash if a lot of changes are made here, so care and full testing is needed.

Experimentation is needed. If folks find out what does what, please let me know and I’ll try to publish a collated guide as an appendix later. FSUIPC offers one special extra control. Just set the aircraft ID and an FS control of 0xFFFF (65535) and the aircraft will be deleted. Note that you can write these values in separate FSUIPC Writes, but if you do the ID must be last, as it is only when this is written that the control is activated.

2DE0	8	For FS2004 only, Wind direction at the aircraft, in degrees True, as a 64-bit double floating point. This can be written to directly affect the wind direction at the aircraft. This value is set before FSUIPC performs any smoothing or limiting actions, and effectively become the new target value. FSUIPC sustains this as a target for a maximum of 14 seconds, with the next write to the same location restarting this timeout. After the timeout has been allowed to expire the intended FS value will take over, with smoothing and so on if enabled. Note that wind direction set in this fashion is not reflected in any weather data supplied by the weather system in FS nor FSUIPC. It is acting locally to the aircraft and can be monitored by Shift+Z or the ambient weather read-outs in FSUIPC.

Normally all zero, set the following bits to actually disconnect the specific joystick axes (from least significant bit = 0): 0 Elevator 1 Aileron 2 Rudder 3 Throttles (all) 4 See below 5 Elevator trim This feature is intended for use in protecting autopilot flight from interference from axis flutter. In order to protect the user from a broken or crashed application, all the flags are cleared 10 seconds after they have been set, so applications will need to repeat the setting every few seconds. If the user option is set to automatically disconnect the trim axis in FS A/P vertical modes, the disconnection of Elevator inputs via bit 0 above also disconnects Trim even if bit 5 is not also set. This allows existing A/P or fly-by-wire applications to work with those user implementations using a trim axis. Additionally, bit 2^4 is available to switch “throttle sync” on. In this mode all throttles are driven from the main throttle or throttle 1 inputs, and other throttle inputs are discarded. (The same option can also be used from an optional Hot Key). See also offsets 3328–3339, which provide the live axis values, post calibration. These would have been applied to FS if not prevented by the flags above. Applications can use these facilities to provide a responsive “fly-by-wire” control.

Normally all zero, set the following bits to actually disconnect the specific slewing axes (from least significant bit = 0): 0 Slew Ahead 1 Slew Side 2 Slew Heading 3 Slew Altitude 4 Slew Bank 5 Slew Pitch In order to protect the user from a broken or crashed application, all the flags are cleared 10 seconds after they have been set, so applications will need to repeat the setting every few seconds.
310C	4	Reserved
3110	8	Operates a facility to send any ‘controls’ to Flight simulator. This works with all versions of FS & CFS. Write all 8 bytes for controls which use a value (axes and all _SET controls), but just 4 will do for ‘button’ types. This is really two 32-bit integers. The first contains the Control number (normally 65536 upwards), as seen in my FS Controls lists. The second integer is used for the parameter, such as the scaled axis value, where this is appropriate. Always write all 8 bytes in one IPC block if a parameter is used, as FSUIPC will fire the control when you write to 3110. Since version 3.40, FSUIPC-added controls (other than the offset ones) can be used via these offsets too. See the Advanced User’s Guide for a current list.

3200	12	These locations operate the FSUIPC facility to send keystrokes to FS. For this to operate correctly the PC must be using Windows 98, ME or 2000. The facilities used just do not exist in Windows 95 nor NT. 3200 message (WM_KEYDOWN or WM_KEYUP) 3204 wParam for the message 3208 lParam for the message All 12 bytes must be written in one IPC write. (This feature is used in WideClient version 3.998 and later, when the [User] parameter "SendKeyPresses=Yes" is included in its .ini file, to relay all non-system (i.e. no Alt key) key presses it receives to the WideServer host).
320C	4	Number of Hot Key slots available for Application Programs to use. Currently this is fixed at 56, representing the 56 DWORDs available in the following offsets:
3210	224	56 DWORDs containing zero (when free for use), or a Hot Key specification as detailed earlier in this document. See also 32FE below.
32F0	4	This DWORD controls some protected mode facilities in FSUIPC, designed to set known conditions in FSUIPC and prevent access to specific menus, whilst an application is running. The whole 32 bit DWORD should be written at once, but the use is divided into Bytes, as follows: Bits 0–7 (byte at 32F0): FSUIPC option settings 2^0 Sets FSUIPC “normal defaults” 2^1 Sets FSUIPC “minimum weather defaults” any non-zero value in this byte stops entry to FSUIPC options Bits 8–15 (byte at 32F1): Flight Sim menu restrictions 2^10 Disable World menu 2^11 Disable Aircraft menu 2^12 Disable Flights menu 2^13 Disable Options menu 2^14 Disable Flights, Aircraft and World menus 2^15 Disable ALL Menus Bits 16–23 (byte at 32F2): reserved Bits 24–31 (byte at 32F3): Timeout (in ticks or 55 mSecs units) The application must write this DWORD regularly for the restrictions to stay in place. The count in the high byte is decremented by 1 every 55 mSecs, so a maximum time of 14 seconds can be set. To be safe the application should be re-writing this with a count of FF (255) every 5 or so seconds, especially if it is likely to be running across WideFS. When the count expires, or the application whites a zero DWORD here, all the options and menus return to normal.
32F4	2	The 16-bit ID of the last menu command item accessed in FS can be read here. By “access” is not meant “used”–that cannot be determined easily. Just having a menu command highlit will denote an access. To decode command Ids, use FSUIPC logging. First, before running FSUIPC set “Debug=Please” and “LogExtras=64” into the FSUIPC.INI file. Then run FS and select the menu items in which you are interested. Examine the FSUIPC Log afterwards to determine the ID.
32F6	2	FSUIPC selected technical option inhibits. Set bits here to turn off specific options and prevent the user turning them back on, for a limited time (max 14 seconds). To keep options turned off you need to write this mask at regular intervals (e.g. every 5 seconds). Note that this is not obeyed if the user has selected to option to disallow all external control of his options. If he has done this, you can detect it by reading this location back within the time limit. If it is zero, not the value written, then the user is preventing your control over his settings. Bits allocated so far are as follows (bit 0 = 2^0 bit): 0 Reverse elevator trim sense 1 Fix control accelerations 2 Rudder spike elimination 3 Elevator spike elimination 4 Aileron spike elimination 5 Autopilot altitude fix (enable V/S sign corrn.) 6 Extend battery life 7 FS clock seconds sync
32F8	1	This provides options to inhibit certain aircraft operations, for use in breakdown or precise control implementations. Set individual bits for individual subsystems. Currently the following are available, all related to hydraulic power: 2^0 Set to inhibit flap operation 2^1 Set to inhibit spoiler operation 2^2 Set to inhibit gear operation Note that these stop operation from axis and button controls very well, and also from key presses and mouse clicks—but in these latter two cases it is done by detecting a change in the system and changing it back. This works, but the device will sometimes try to move, and this can be noticeable, especially for some reason with the flaps—the indicator gives a little jump and the noise briefly starts. [ FS2002 and later only]
32F9	1	Reserved
32FA	2	Text display control word. You can display messages from an external program just like an Adventure. Write the message as a zero-terminated string to offset 3380 (see below), subject to the maximum of 128 characters including the zero terminator, then write a number to this offset, 32FA, as follows: 0 display till replaced +n display for n seconds, or until replaced –1 display and scroll, or until replaced –n display and scroll, or for n seconds, or until replaced In the last two cases, whether the message scrolls or not depends upon the setting of the “Options—Settings—General—Text Display” option. See also offset 1274 above, and the “white messages” option in 3302 below.
32FC	2	AIR file change counter (incremented by FSUIPC whenever the AIR file as defined at offset 3C00 changes). This is also incremented when the FS2004 control to “reload user aircraft” is detected—assign it to a joystick button or to a Key in FSUIPC for this. FSUIPC cannot detect controls arising from key presses assigned in FS dialogues.
32FE	1	Hot Key change counter, incremented by FSUIPC whenever any of the Hot Keys defined in the table at offset 3210 occurs and therefore has its flag set by FSUIPC.
32FF	1	Hot Button change counter, incremented by FSUIPC whenever any of the Hot Buttons defined in the table at offset 2910 changes state in the right way, and therefore has its flag set by FSUIPC.
3300	2	[FS2k, CFS2 and FS98, as applicable] Additional radio and autopilot status indicators (read only access). Allocation by bits which are set when true. Bit 0 = least significant (value 1): 0 = reserved 1 = good NAV1 2 = good NAV2 3 = good ADF1 4 = NAV1 has DME 5 = NAV2 has DME 6 = NAV1 is ILS 7 = AP NAV1 radial acquired 8 = AP ILS LOC acquired (incl BC—see 10) 9 = AP ILS GS acquired 10=AP ILS LOC is BC 11=good ADF2 (FS2004) 12=NAV2 is ILS 13–15 reserved
3302	2	Assorted FSUIPC options, set by user parameters: read-only via the IPC. Those allocated so far (bits from least significant): 0 = Static (i.e. non-scrolling) messages sent to FS are to be displayed in white rather than the default red. (If AdvDisplay is installed it must be version 2.11 or later for this option). 1 = This is FS2004 (or later) but MakeItVersionFS2002 has been used in the INI to “fiddle” the reported value in 3308 to show FS2002.
3304	4	FSUIPC version number: The HIWORD (i.e. bytes 3306-7) gives the main version as BCD x 1000: e.g. 0x1998 for 1.998 The LOWORD (bytes 3304-5) gives the Interim build letter: 0=none, 1-26=a-z: e.g. 0x0005 = 'e'
3308	2	FS version, as determined by FSUIPC: Currently only one of these: 1 = FS98 2 = FS2000 3 = CFS2 4 = CFS1 5 = reserved 6 = FS2002 7 = FS2004 “A Century of Flight” (see also bit 1 in offset 3302 above)
330A	2	Fixed read-only pattern, set to 0xFADE. Use this to check that the values in 3304-3308 are valid (Note: the supplied LIB writes its version number here, but this has no effect and is only for assistance when viewing LOG files).
330E	1	Count of external IPC applications seen connecting since the session began. Keeps increasing till it gets to 255 then stays at that value.
330F	17	Reserved area for WideFS KeySend facility (version 4.23 and later)
3320	2	This word is used to activate a facility supported by WideFS to automatically shut down the PCs running WideServer (i.e. this one) and WideClient. The .ini files of each WideFS component which is to activate the shutdown needs the “AllowShutdown=Yes” parameter included. The application performing the shut down action must write 0xABCD to this offset. WideServer automatically resets this word to zero 5 seconds afterwards, before it initiates its own PC’s shutdown if specified. This delay is to ensure the Clients get the message before the host dies, and the clearing to zero is done so that the survivors can continue. Since version 5.30, WideFS also provides the lesser option “AllowShutdown=App” which only closes down the WideClient or, in the case of WideServer, the FS session. Later still the “AppOnly” variation was added, which keeps WideClient running, ready to reload the applications when FS restarts. A hot key facility to invoke this WideFS shutdown from the FS keyboard is added in version 5.301 of WideServer. Since version 6.40 of WideFS the pattern 0xDCBA written here invokes a “close application” action. On all WideFS PCs with any form of shutdown allowed, this pattern closes only those applications loaded by WideFS and leaves WideClient running ready to reload them. On the Server, if it is allowed, it closes FS itself. A hot key facility is provided for this variant, too.
3322	2	WideServer version number, if running and if version 5.00 or later. Otherwise this is zero. This is a BCD value giving the version number x 1000, for example 0x5110 means version 5.110. See also offset 333C.
3324	4	This is the altimeter reading in feet (or metres, if the user is running with the preference for altitudes in metres), as a 32-bit signed integer. Please check offset 0C18 to determine when metres are used (0C18 contains ‘2’). The same value can be calculated from the actual altitude and the difference between the QNH and the altimeter “Kollsman” pressure setting, but this value ensures agreement.
3328	2	Elevator Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
332A	2	Aileron Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
332C	2	Rudder Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
332E	2	Throttle Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A). This is the single throttle, applied to whichever engines are denoted by the bits in offset 0888.
3330	2	Throttle 1 Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
3332	2	Throttle 2 Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
3334	2	Throttle 3 Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
3336	2	Throttle 4 Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
3338	2	Elevator Trim Axis input value, post calibration, just before being applied to the simulation (if allowed to by the byte at offset 310A).
333A	2	Throttle lower limit (FS2002 and later only). This is normally 0 if no reverse is available, otherwise gives the reverse limit such as –4096 (for 25%). For earlier versions than FS2002 this location will be zero.
333C	2	WideFS flags: only set from version 5.50 or later of WideFS. Flags used so far are: 2^0 1 =if TCP is being used, 0 if SPX 2^1 1 if connected at all, 0 is waiting for connections See offset 3322 for WideFS version number, which also confirms that WideServer is installed and running.
333E	2	Weather clear count: This is incremented every time FS’s “clear weather” routine is called, for whatever reason.
3340	36	This area is used for externally signalled “joystick button” control. Each DWORD or 32 bits represents one “joystick” with 32 buttons. If an external program sets or clears a bit in any of these 9 DWORDS the “Buttons” page in FSUIPC will register the change as a button operation on one of Joystick numbers 64 to 73 (corresponding to the 9 DWORDs). So, FSUIPC can be used to program whatever actions the user wants.
3364	1	FS2004 “Ready to Fly” indicator. This is non-zero when FS is loading, or reloading a flight or aircraft or scenery, and becomes zero when flight mode is enabled (even if the simulator is paused or in Slew mode).
3365	1	“In Menu or Dialog” flag. This byte is non-zero when FS is effectively paused because the user accessed the Menu, or is in a dialogue resulting from menu or other selection activity. The non-zero values are: 1 = FS frozen because of menu activity 2 = FS frozen because of modal dialogue Both bits may be set in dialogues accessed through the menu. Note that the 2 bit may flicker a little on exit from the dialogue, due to the way it is detected. In FS2004 the byte at 3364 should also be considered when using this flag—there are some conditions, like reloading scenery or aircraft or flights, which effectively freeze the sim in ways not detectable except by the method used for the “ready to fly” indicator.
3366	1	This byte reflects the FS2004 “Engine on Fire” flags. I’m not sure if FS actually simulates such events, but it appears to have allocated Gauge-accessible variables to indicate them. This byte uses bits 2^0–2^3 as flags for fires in Engines 1 to 4, respectively.
3367	1	This byte shows doors that are open (FS2004 only). At present this only provides bit 2^0 for the main doors.
336C	2	Frame rate calling counter. This is simply a number that is incremented each time FSUIPC is entered from FS using the entry related to frame rates.
336E	2	Toe brake axes have been selected as “Set” in FSUIPC’s joystick pages if this is non-zero. Byte 336E is non-zero for Left Brake, byte 336F for Right Brake. Note that this only means that the user has told FSUIPC to handle the toe braking, by pressing “Set”. It will only actually do so if it sees brake messages.
3370	4	Four single byte PFC driver “alive” counters: 3370 = COM port read thread alive and running 3371 = Elevator trim motor action (0=off, 1=up, 2=dn) 3372 = COM port write thread alive 3373 = Main FS chain alive N.B. without the main FS chain running the other three aren’t maintained in any case, so mean nothing.
3374	4	This is the “live” millisecond count as used in the FSUIPC Log. It is updated on each FS chained call to FSUIPC.
3378	4	This is the millisecond timestamp value of the most recent line in the current FSUIPC Log. It is updated when each line is logged.
337C	1	Propeller de-ice switch, (1 = on, 0 = off), read for state, write to control [FS2002+]. This should operate with aircraft defined to have the facility, but in fact it merely reflects the older Anti-Ice switch. The TOGGLE_PROP_DEICE control does nothing.
337D	1	Structural de-ice switch, (1 = on, 0 = off), read for state, write to control [FS2002+]. Although this is documented in both FS2002 and FS2004 panel SDKs, with a token value and an FS control, it appears to do nothing. Possibly it needs some action in the AIR file or Aircraft.CFG, but there’s nothing in the official documentation.
337E	2	FSUIPC activity count. Simply a number that is incremented every time FSUIPC receives a call or message from Flight Simulator. This can be used through WideFS to check if FS is still active, for example. Note that when FS is loading aircraft or scenery/textures, this value may not change for many seconds as FSUIPC is then not getting any processor time at all.
3380	128	Message text area, used by AdvDisplay.dll for a copy of the ADVenture text display: useful for programs wishing to display the adventure texts on a separate PC, via WideFS. The text is truncated if longer than 127 characters, there always being a zero terminator provided. You can also write messages to this area, always zero terminated, for display on the FS windshield or via AdvDisplay if it is running. After placing the message text, you must write the 16-bit timer value to offset 32FA to make FSUIPC send the message through to FS (see 32FA above).
3470	8	Ambient wind X component, double float (FS2002+)
3478	8	Ambient wind Y component, double float (FS2002+). In FS2004 (only), values written here are sustained by FSUIPC for up to 14 seconds, or until another value is written. This can be used by applications to provide things like lift for glider soaring, or fast varitions to emulate vertical turbulence. The values written here are not subject to FSUIPC’s smoothing, and won’t be reflected in any normal weather read-outs like ATIS.
3480	8	Ambient wind Z component, double float (FS2002+)
3488	8	Ambient wind velocity, double float (FS2002+)
3490	8	Ambient wind direction, double float (FS2002+)
3498	8	Ambient pressure, double float (FS2002+). This is accurate in FS2004, but suspicious in FS2002.
34A0	8	Sea level pressure (QNH), double float (FS2002+)
34A8	8	Ambient temperature, double float (FS2002+)
3542	2	Standby altimeter pressure setting (“Kollsman” window). As millibars (hectoPascals) * 16. [This is used by FSUIPC to maintain offset 3544. It is not used by FS at all]
3544	4	This is the standby altimeter reading in feet (or metres, if the user is running with the preference for altitudes in metres), as a 32-bit signed integer. Please check offset 0C18 to determine when metres are used (0C18 contains ‘2’). This value is maintained by FSUIPC using the pressure setting supplied in offset 3542. It isn’t used in FS itself, but is supplied for additional gauges and external altimeters so that the standby can be kept at the correct (or last notified) QNH whilst the main altimeter is used for Standard settings (for airliners flying Flight Levels).
3548	8	Horizon bars offset, as a percentage of maximum, in floating point double format. (–100.0 down to +100.0 up). On the default Cessnas the maximum offset is 10 degrees. [Read only on FS2004]
3590	4	Engine 1 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]
3594	4	Engine 2 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]
3598	4	Engine 3 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]
359C	4	Engine 4 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]

3BA8	44	Area used only in PFC.DLL. Please see its documentation for details.
3BD2	2	This is a 16-bit counter that is incremented each time a FLT file is saved in FS. This applies to flights saved through FS Flights menu, the shortcut key (;), AutoSave, and via the FSUIPC flight saving facilities. Flight filenames can be read using the path reading facility at offsets 0FF0 ff.
3BD6	18	Panel failure modes (FS2002 and FS2004 only): one byte flag/control for each of the following “partial panel” modes: 3BD6 ADF (both on FS2004) 3BD7 ASI 3BD8 Altimeter 3BD9 Attitude Indicator 3BDA COMM1 3BDB COMM2 3BDC Compass 3BDD ? (unknown) 3BDE Engine (see 0B6B for separate engines) 3BDF Fuel Indicator 3BE0 Heading Indicator 3BE1 NAV1 3BE2 NAV2 3BE3 Pitot heat 3BE4 Transponder 3BE5 Turn Co-ordinator 3BE6 Vacuum 3BE7 VSI
3BE8	8	Attitude Indicator failure timer, as a double floating point value.
3BF0	4	Attitude indicator lock indicator, 32-bit integer but probable only Boolean (0 or 1) [FS2k/CFS2 only]
3BF4	4	Low vacuum indicator, 32-bit integer but probable only Boolean (0 or 1) [FS2k/CFS2 only]
3BFA	2	Flaps dTtente increment. The full range of flap movement is 0–0x3FFF (16383). Each dTtente position or “notch” is spaced equally over this range, no matter what flap angle is represented—a table in the AIR file gives those. To obtain the number of dTtentes, divide this increment value into 16383 and add 1. For example 2047 (0x7FF) would be the increment for 9 positions as on the default FS2K 737.
3BFC	4	Zero Fuel Weight, lbs * 256. This is the aircraft weight plus the payload weight, minus fuel. In FS2004 this changes as the payload is adjusted.
3C00	256	Pathname of the current AIR file, excluding the FS main path (see 3E00), but including everything from “Aircraft\…” to the final “…air”. This is zero padded to fill the 256 bytes available. When this changes the 16-bit counter at 32FC is incremented, so interested programs don’t have to keep on reading the whole 256 bytes to check.
3D00	256	Name of the current aircraft (from the “title” parameter in the AIRCRAFT.CFG file). Valid for FS2K only.
3E00	256	Path of the Flight Simulator installation, down to and including the FS main folder and a following \ character. If the PC is on a Network and the drive or path is shared, then the full UNC (universal naming convention) path is given. Examples are: D:\FS2000\ (non-Network) \\MyMainPC\drived\FS2000\ (Network, named PC and named shared drive))
3F00	2	To load or save a Flight (FS2000/2002) or Situation (FS98) you first set up the pathname (and optional description) at offset 3F04 below, then write here. Write one of these values: 0 to simply load the specified flight/situation. 1 to save the flight/situation with an empty description 257 to save the flight/situation with a description as well This facility works on FS98, FS2000 and FS2002 but not CFS1 nor CFS2. Also note that for Loading you don’t have to have the files in the “Pilots” or “Situatio” folder (or “flights” for FS2002)—any folder within the FS main folder can be used to load Flights/Situations. However, they can only be saved in “Pilots” (FS98/FS2000) or “Flights\MyFlts” (FS2002), and this folder is assumed by default. If you are Loading a file, please allow time for the file to load before expecting any further meaningful response across the FSUIPC interface. FSUIPC will probably not be able to respond for several seconds even on the fastest machines.
3F02	2	FLT/STN file loading counter (incremented by FSUIPC whenever the FLT or STN file, as defined at offset 3F04 changes or is reloaded). This word is read only—attempting to write here will do no harm.
3F04	252	READ: (FS2000/2002/2004 only) Pathname of the currently loaded FLT file, excluding the FS main path (see 3E00), but including everything from “Pilots\…” or “Situatio\…” (or “Flights\” in FS2002), or whatever, to the final “.flt” or “.stn”. This is zero padded to fill the 252 bytes available, or truncated if longer. When this changes (or simply reloaded) the 16-bit counter at 3F02 is incremented, so interested programs don’t have to keep on reading the whole 252 bytes to check. WRITE: (FS2000, FS2002, FS2004 and FS98) Write the file name for the FLT+WX (FS2000/FS2002) or STN (FS98) file you wish to Load or Save. The name can include the final “.flt” or “.stn” but this will be discarded in any case. You can specify a folder (existing within FS’s main folder) such as “Pilots\” or “Situatio\” (“Flights\MyFlts\” in FS2002) for Loading, but files can only be saved to “Pilots\” in FS98/2000, “Flights\MyFlts\” in FS2002 and in your documents folder in FS2004. If you give a path for saving, it is discarded. There must be a zero terminator. If you are writing the file, a description can also be specified, following the pathname and its zero terminator. Obviously this is limited by the space available. It must also be terminated by a zero byte, and indicated in the value written to 3F00 above. See 3F00 above for details of actually Loading or Saving the Flight or Situation so identified.
