Add standard ICAO sim variables

Please add the following aircraft.cfg parameters as variables to SimConnect:

  • icao_type_designator
  • icao_manufacturer
  • icao_model
  • icao_engine_type
  • icao_engine_count
  • icao_wtc
  • icao_airline

These are important general parameters that describe aircraft and its capabilities in a standardized way used throughout the aviation sector.

Prior to FS2024, we could at least scan through the filesystem to read values directly from aircraft.cfg files, but with the simulator now locked down more than before and many files streamed on demand, this not a viable solution anymore.

Knowing these parameters is very important for all kinds of applications that depend on aircraft type. For example, our VDGS module uses ICAO type designator to select proper guidance method and show aircraft type on interactive docking devices.
