Trim switch ergonomics with stick shaker on
We see several trim switch applications.
Why so short and ineffective?
Did the shaker interrupt the switch contact (perhaps not held down with sufficient force)?
Are pilots trained in trimming with shaker on?
Was the pilot used to or schooled in only doing short blips?
How long (or how many blips) would it take to trim out an MCAS excursion – which if recollection is correct moves the stab much faster than the trim switch?
And lastly: how well do pilots perceive stick force when the shaker is on?
