To provide an altimeter and a speed indicator by which the correlation of a plurality of displayed values can be judged instantaneously and the work load of a pilot be also reduced.

A symbol SA comprised of a long pointer and a short pointer, a symbol SB provided with a triangular recessed part, and a band-like symbol SC are arranged on an altitude indicating screen. The symbol SA indicates present altitude of an aircraft outputted from an ADC 12, by a rotary angle, the symbol SB indicates present altitude target value instructed by an FMC 13, by a rotary angle, and the symbol SC indicates a difference between the altitude of the aircraft and the altitude target value, by a thin line, from the long pointer indicating position of the symbol SA to the edge of the symbol SB in an anticlockwise direction.
