Flying is a right hand brain activity. At least the handling portion is.
The right hand side of the brain dosn't do abstractions like numbers, at
least not until the left hand side (which can't fly worth a ****) sends
it over to the right side in a readily digestable form which enables the
right brain to chew it into a picture.

An analogue display cuts the left hand side out of the loop and enables
the calcualtion rate to increase the right sides "frame rate" so that
corrections can be made more frequently thus enabling the pilot to fly
the airplane more smooothly and with more authority.

Most of this is pure speculation, although it is interesting.

People who prefer the numbers usualy don't fly very well at all.

Unless, of course, they are flying an airliner in which systems are more
important than hand-flying. In that case, they may be a lot better at it.

You don't do trig while you're shooting pool and expect to win the game.

Some people do (cf. card counters).
