Autothrottle reduces power in turns !!

Recommended Posts

During climbs with autothrottles engaged, engine power is often close to max possible power. When the aircraft turns, the autothrottle system always reduces the power, even if the current airspeed is lower than the requested airspeed !!This is very annoying because a loss of speed occurs, and it can induce a stall. Anyway, the aircraft often has a lot of difficulties to reach a correct airspeed after that.Is there a way to avoid this?Is it possible to configure FS2002 or the aircraft to prevent this "slowing" effect?Thanks,Eric

Yes, I have noticed this effect. It will also do it during cruise, when making large turns toward a waypoint. This is especially evident when the aircraft is off track due to winds and tries, at the last moment, to make the waypoint. The aircraft will then roll back to the outbound heading. It usually results in an underspeed condition or overspeed condition, due to the winds.For climbs, I usually set the aircraft speed to 260kt vice 250 when below 10000ft, above 10000ft - 283kt. I also set the vsi to 2800fpm and then adjust downward during the climb to keep N2 at about 83%.

MS decided to fix nothing in FS2K2, no telling what will be messed up in the next version.RAF
