Sudden uncommanded max pitch demand during auto

[Naterater (Nathan E)]

Running 3.8.5 beta 3 (this was just before the 3.8.5 release) on a Cube. Pretty much everything is standard setup. Running RFD900’s. Believer twin-engine foamie.

Plane is in the middle of an auto mission flight line and suddenly pitches up, loses speed, and stalls. I have no idea why the Desired Pitch jumps to 30-degrees in the middle of a flight line. There is no altitude demand increase nor any increase in channel2_in. This has happened more than once. @tridge @MagicRuB

Your Gps speed and Airspeed are quite different .

The most interesting to me is why plane took a lot of altitude without apparent reason , TECS.hdem was flat and no elevator command .
