Title says it all really- for planning and better understanding I am just trying to get my head around how things work to help with planning approaches, especially down wind approaches. I know that the native Copter firmware used groundspeed and that Plane uses airspeed but where do we stand in VTOLs? Thanks everyone.
Hi Angus,
That’s a good question!
The Q Flight Modes in a VTOL are derived from copter code and I believe it has no knowledge of an external AS sensor.
Perhaps we can get some dev help to answer this question properly. @hwurzburg @iampete
Q modes use ground speed and forward flight modes use airspeed.

Awesome, thank you for that.
Sorry to be a pain but one other related question, does this remain the same for WPNAV in both modes ie WPNAV is windspeed based in plane?
Angus,
WPNAV is a copter parameter. In Plane (or VTOLs), it’s Q_WP_ACCEL. I would assume that Q_WP_ACCEL uses ground speed when you are in a copter flight mode of the VTOL…but the description doesn’t really say.
For VTOL and Plane forward flying, TECS is used along with an AS sensor.
Cheers!
