AMC1 ACNS.C.PBN.280 Deviation display

ED Decision 2019/011/R

An acceptable means of compliance is to provide a non-numeric deviation display. The full-scale deflection of the non-numeric lateral deviation display should be:

(a)     comparable with the applicable RNP value; and

(b)     made available to the flight crew.

Alternatively, subject to EASA’s agreement, a moving map display with appropriate map scales, and which provides a sufficiently equivalent functionality to a non-numeric lateral deviation display, may be accepted. EASA’s agreement will be based on a human factor and workload assessment performed by the applicant.
