Hello i'm using 3.0.2 v. Drone Kit and I discovered bug with GroundSpeed and AirSpeed, because i have always this same values (ground speed values is correct), so take a closer look.

In class Speed we can set airSpeed, only one method using this ArduPilot.setAltitudeGroundAndAirSpeeds, but here we have problem.

• first function where we used is from ArduPilot.processVfHud (here we have corrected values)
• second function where we used is ArduPlane.processGlobalPositionInt , in my opinion we don't should calculate speeds (because we have in processVfHud) but bigger problem is transmissions value groundSpeed to groundSpeed and airSpeed. Look my link https://github.com/dronekit/dronekit-android/blob/develop/ClientLib/src/main/java/org/droidplanner/services/android/impl/core/drone/autopilot/apm/ArduPlane.java#L67

The parameters which take: altitude, groundSpeed, airSpeed, climb

Ok now i know why doesn't work properly. Class ArduPlane:

@Override
protected void processVfrHud(msg_vfr_hud vfrHud){
   //Nothing to do. Plane used GLOBAL_POSITION_INT to set altitude and speeds unlike copter
 } 

Can anyone add me to contributors, please ?
