ED Decision 2013/031/R

(See AMC1 ACNS.E.RVSM.030)

(a)     The automatic altitude control system controls the altitude within ±20 m (65 ft) about the selected altitude, when the aircraft is operated in straight and level flight under non-turbulent non-gust conditions.

(b)     The tolerance of the alert issued when the altitude displayed to the flight crew deviates from the selected altitude by a value of ±60 m (±200 ft) or greater is no greater than ±15 m (±50 ft).

(c)      Where an altitude select/acquire function is provided, the altitude select/acquire control panel is configured such that an error of no more than ±8 m (±25 ft) exists between the value selected by, and displayed to, the flight crew, and the corresponding output to the control system.
