I flew a high-performance aircraft for the first time recently (SR22T) and nearly ground-looped the thing during a touch-and-go because the instructor gave me absolutely zero pre-flight instruction (my brother is taking lessons and I'm certificated with ~100h in a 172, which I made abundantly clear).
There are two contributing factors in my mind:
- I was making copious use of the nose-up trim during final for a zero control-pressure at approach speed. The landing was butter, but as I advanced the throttle the thing literally jumped off the runway and I panicked as I tried to keep it in ground effect without adjusting the trim.
- I advanced the throttle quite aggressively which caused an enormous amount of yaw, where during my panic, instead of rudder, I tried to steer the thing like a car with the obvious result. Luckily we were off the ground and avoided a worse-case result, though I'm pretty certain that the AFCS(a) saved us from stalling out in the chaos.
- (bonus) The instructor quite obviously abdicated his responsibility to the safety of his passengers and the aircraft. Though, I have enough experience that I should not have flown without a briefing.
It was terrifying and it has made me apprehensive about taking the controls of such an aircraft again.
What briefing or process should the instructor have used that would have ameliorated this outcome? How should you handle trim on such an aircraft for a touch-and-go?
(a): The SR22T I flew had a Garmin G1000 with an Automatic Flight Control System, which includes a feature sometimes referred to as "envelope protection" that is active even with the autopilot disconnected. One aspect of this protection is that it will (for example) reduce AoA like the stick pusher in a commercial aircraft to keep it within its safe flight envelope, preventing a stall.
