VTOL parameters VT_MC_ARSPD_MIN & TRIM

Next week, we want to perform the first test flights with our tiltrotor in coptermode.
But two VTOL parameters are still unclear to me:
VT_MC_ARSPD_MIN (minimum airspeed in multicopter mode) and VT_MC_ARSPD_TRIM (trim airspeed when in multicopter mode). What is the sense of these parameters ?

@tumbili Please respond.

Hi,

this is not used for tiltrotors. It was only related to the tailsitters.
