AMC1 ACNS.B.VCS.030 Continuity
ED Decision 2019/011/R
For aircraft that are foreseen to be operated within airspace where continuous air-ground voice communications is required, the continuity of the voice communication system is designed to an allowable qualitative probability of ‘remote’, except for
(a) Class I aircraft, as defined in FAA AC 23-1309-1E, certified to a CS-23 amendment prior to 5, and;
(b) aircraft with type code 1SRXXXXX or 2SRXXXXX as defined in ASTM International Standards F3061/F3061M – 17 and certified to CS-23 Amendment 5 or subsequent amendments
where the continuity of the voice communication system may be designed to an allowable qualitative probability of ‘probable’.
