2783.Many altimeters contain linkages that rotate a numerical counter in addition to moving pointers around the dial.A quick reference window allows the pilot to simply read the numerical altitude in feet.The motion of the rotating digits or drum-type counter during rapid climb or descent makes it difficult or impossible to read the numbers.Reference can then be directed to the classic clock-style indication.
