Configuration:BasicTuning:Throttle Cruise vs Airspeed Cruise

Can some explain the relationship of these parameters?

I think Airspeed Cruise is:
Target airspeed (ArduPlane:TRIM_ARSPD_CM): Airspeed in cm/s to aim for when airspeed is enabled in auto mode. This is a calibrated (apparent) airspeed.

I think Throttle Cruise is:
Throttle cruise percentage (ArduPlane:TRIM_THROTTLE): The target percentage of throttle to apply for normal flight
:black_medium_small_square:Range: 0 100
:black_medium_small_square:Increment: 1
:black_medium_small_square:Units: Percent

How do these relate? It would seem to me they can’t be set independently. I have Airspeed Cruise set to 8 m/s (800 cm/s). I was hoping that in Auto, while flying between waypoints, I’d be doing so at 8 m/s. In fact telemetry indicates about double that.

are you using an airspeed sensor?

trim_throttle is for no airspeed
TRIM_ARSPD_CM is for with airspeed sensor

Hi,
Can u recommend settings to each with n without airspeed sensor, as an example.
Thanks
