Rumor has it that MPO is not implemented yet, which would make sense since the FM is still in development. I don't know whether it is or isn't though.
I would also expect user to exploit systems, like MPO, in dogfights or other regimes of flight. Players use overrides designed for safety to get performance gains where they would probably damage the jet or cause it to depart. I hope they implement, or update, how the MPO works to what you show if what you show is accurate.
