Decision 2021/008/R
COMMON GUIDANCE APPLICABLE TO ALL SOLUTIONS
(a) The failure condition of point (a) of AMC1 ACNS.E.LAD.620 for the case of erroneous automatic activation is intended to prevent that a large number of false alerts are caused by erroneous automatic activation of the system and have a significant and worldwide impact on SAR authorities.
(b) A piece of equipment that is part of the system and that contributes to the failure condition of point (a) of AMC1 ACNS.E.LAD.620 could be inactive when the system is not activated, including when the system is armed. This piece of equipment could be, for example, a processor in sleep mode or an ELT. If errors in the design of the software or of the electronic hardware of such piece of equipment do not cause undesirable automatic activation of the system when that piece of equipment is inactive, that software and electronic hardware may be developed in accordance with design assurance level (DAL) D.
