FMC and AP++

FMC and AP++ are extensions created exclusively for GeoFS by Harry Xue and Qantas94Heavy. They give players great control over climb, descent and speed. The FMC primarily assists with full-fledged flights as it will automatically turn the aircraft as needed.

AP++
AP++ is an extension that provides significantly greater control over the default GeoFS autopilot. Airspeed changes from True to Indicated, and an additional Mach number option is available. Apart from that, V/S and waypoint heading are also enabled.

FMC
FMC (Flight Management Computer) primarily assists with IFR flights. By entering navigational aids, the computer will automatically adjust the autopilot system when a NavAid is reached. FMC requires AP++.

Vertical Navigation (VNAV) is available on FMC. Premade routes are also available.
