Also, a very simple modification is to clock all mechanical gauges so that the needle position for normal readings all point the same direction. Left. Right. Up. Down. Doesn't really matter. Just all the same direction. Screws up the look of the panel while on the ground at airshows, as the scales are all over the place. But, in the air a scan becomes just verifying that all the needles are pointing in the same direction.

Some predict that most of the ‘systems’ will eventually change back to previous ‘control’ methods away from ‘touch’ screens.
Years ago the control by deviation allowed hundreds of process controllers to be monitored by just a few people. Basically a red pointer showing from behind the green area on the controller display was reason for an employee’s attention.
A study by the military (led by my Son [FAA employee]) determined the control by exception was preferred rather than reading number digits requiring the mind to decide if that was normal or not.
This retired GE process control tech (over 30+ yrs experience) has not welcomed touch screens and their digital displays from the beginning. I hope that the change back comes sooner rather than later.. Earl Schroeder.
