Where has it been verified that the STS was trimming the wrong way, (meaning 'reversed operation', counter to pilot intention)
It wasnt...it was trimming as designed...but to the pilot it appeared to be trimming the wrong way..... makes sense as he had corrupted CAS data.
What should Captain have done to get Stab Trim looking at B?
He cant as far as I know.FCC A commands the signal from power up.After landing,the squat switch on the gear will change it to FCC B for the next flight.The pilot must disengage AP stab trim to stop the unwanted trim.Using electrical trim overrides it but wont disable it.After 5 seconds,STS will trim again.Pulling on the stick will stop the trim but again it will start trimming if stick pressure is released.It has to be disabled in a UAS(or rather this particular UAS scenario).Ive never encountered this problem during UAS in simulator.However,this doesnt mean it cant happen.Too many variables.....ie type of UAS,which FCC is controlling etc.
