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
04C2	2	>fs2k adventure weather: This provides the cloud_thunder_base in metres AMSL

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
04D2	2	Precipitation control: write hi-byte=type 0–2 (see above), low byte=rate 0–5. Write 0xFFFF to release control back to FS2k/CFS2.
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.
04DA	2	Surface layer wind direction, *360/65536 to get degrees MAGNETIC (FS2k/CFS2). This may be different to the current wind direction at the aircraft—see offset 0E92. This also provides wind_surf_dir 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]

05DE	2	Slew control: write non-zero value here at same time as changing 05DC above, and the Slew mode change includes the swapping of the assigned joystick axes. [ignored in FS2004 – the axes are swapped in any case. See offset 310B for control of axis connection in slew mode]
05E4	2	Slew roll rate: 0=static, –ve = right roll, +ve=left roll, rate is such that 192 gives a complete 360 roll in about one minute.
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.

062C	4	Instant replay: time left to run, in seconds. Whilst this is non-zero, the flag in offset 0628 controls the playback.

088E	2	Engine 1 Prop lever, –4096 to +16384
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.

08B8	2	Engine 1 Oil temperature, 16384 = 140 C.

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.
08D8	4	Engine 1 Hydraulic pressure: appears to be 4*psi
08DC	4	Engine 1 Hydraulic quantity: 16384 = 100%
