AMC1 ACNS.E.LAD.420 Position accuracy for survivable accidents

ED Decision 2021/008/R

ACCEPTABLE MEANS OF COMPLIANCE APPLICABLE TO ALL SOLUTIONS

(a)     Compliance with CS ACNS.E.LAD.420 should be demonstrated through the assumptions on the performance of the communication infrastructure that are provided in accordance with CS ACNS.E.LAD.320.

(b)     Compliance with CS ACNS.E.LAD.420 should be demonstrated under nominal GNSS satellite constellation conditions.

(c)      If an ELT is used to comply with CS ACNS.E.LAD.420, that ELT should:

(1)     be a second-generation automatic ELT or an ELT(DT);

(2)     transmit an encoded position and use a message-coding protocol that is compatible with the position accuracy objective of CS ACNS.E.LAD.420;

(3)     have capabilities G (internal/integral GNSS receiver) and C (crash survivability); and

(4)     be automatically activated upon detection of a crash impact.
