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.
