air_data

AirData interface. Provides an interface for baro absolute and differential pressure as well as airspeed. Subscribes to BARO_ABS, BARO_DIFF and TEMPERATURE ABI messages and calculates QNH and true airspeed from it. Also enables you to fly on “flight levels” using AMSL (AltitudeAboveSeaLevel) calculated from current pressure and QNH. When using this module to provide airspeed you need a differential pressure sensor module publishing the BARO_DIFF ABI message. Make sure to disable other modules which otherwise directly set the airspeed in the state interface. E.g. when using the airspeed_ms45xx.xml module, define USE_AIRSPEED_MS45XX to FALSE.
