Until the computer fails, that is.

Mechanics are not failure-free either. In fact, during my brief aviator
career I've already experienced two (2) creeping altimeters and one (1)
stuck VSI. The worst, however, was an airspeed indicator that did not move
until the airplane was up to 35 knots. Makes for interesting decision
situations during take-off. I still don't know if the fault was in the
instrument or if there was water or a bug in the pitot line.
