Trim display and restricted sim availability
Two holes in the cheese:
Control surface position can be displayed on many ECAMs, along with flaps, spoilers, gear, etc. But where are trims shown besides on the wheel and knobs?
It may really help to show trim positions on the ECAM - and what is moving it when in motion: MAN, AP, STS, MCAS.
It might have helped the AF447 crew, especially if control stick/wheel disagree was displayed. But that would cost money and certification effort to develop.
A repeating theme in many posts is the expense, and consequential dearth, of sim sessions to explore the corners of the envelope. Crews are being trained to minimum standards because sims, and performance data in the corners of the envelope, cost money.
Now we see an imperative to develop new designs in a way that minimises, or even better eliminates, sim time.
The MBAs have succeeded at pinching carloads of pennies – but airframes are now outwitting the crews.
