Hi All,Since a couple of days I'm trying to realize a current Airspeed and Altitude Hold function for an older Turboprop Aircraft. Seems that there is no usable code for it. I've also tried to set the Airspeed via (A:Airspeed select indicated or true,knots) s1 and l1 (>K:AP_SPD_VAR_SET) by a mouseclick. It works as far as the current Airspeed was given to the AP. Unfortunately the AP doesn't hold this speed. I've also checked the Aircraft.cfg and Airfile. Everything seeems to be allright there (Autothrottle is available and Arming is not required. Does anybody know an easier way to realize this function?Best RegardsMatthias

Oooops, at the moment I found the mistake in the Aircraft.cfg. The value for autothrottle_max_rpm was much too low so nothing could work of course. Now everything works perfect (could also solve the Altitude hold with another trick).
