40s is only enough if you know what to do right away from the start of the situation. A failing sensor may confront the pilots with many (unrelated to a trim runaway) warnings (like unreliable airspeed, stick shaker, alt disagree). That has been the case for Lion Air at least.
- sokoloff 8y agoTake a car analogy. Suppose your car starts drifting into oncoming traffic. Maybe the road crown changed, maybe your alignment changed from a debris strike, maybe you have a tire going down, maybe you have a crosswind. In all those cases, your reaction is the same and instinctive regardless of whether or not you know the root cause. Flying an airplane manually on instruments, the pilot sees the airplane undershooting the pitch target and pulls back on the control column every bit as naturally as the car driver above. When the pitch target is correct and the control force high, use the stab trim to take the force away. This is every bit as much a continual process as the driver lane keeping. If MCAS is trimming against you every time you let go of the trim, you get feedback that this is likely a trim issue. Keep flying the airplane and trimming as needed. This is not a case where the airplane automation fails and an airplane suddenly gets “dumped” onto a pilot who has to regain control and figure things out. It’s obvious that the time and space available was not enough for that Lion Air or that Ethiopian Air flight, so you have real world evidence to support your point. I acknowledge that fact, of course.
