GM2 ACNS.E.LAD.240 Automatic activation ED Decision 2021/008/R GUIDANCE FOR SOLUTIONS BASED ON AN ELT(DT) AND FOR SOLUTIONS BASED ON HRT The purpose of point (c) of [AMC2 ACNS.E.LAD.240](#_DxCrossRefBm573002923) is to activate the system when a condition occurs during the flight that: (a) is unlikely during normal aircraft operation (e.g. the simultaneous loss of independent data sources that are used by the automatic triggering function), but possible in some accident scenarios during which the aircraft is severely damaged (such as in-flight fire, uncontained engine failure, explosive decompression, etc.); and (b) disables the automatic triggering function before the activation criteria used by that function are met. Equipment failures that occur during normal aircraft operation are not within the scope of [AMC2 ACNS.E.LAD.240](#_DxCrossRefBm573002923). They are addressed by integrity requirements (refer to [CS ACNS.E.LAD.620](#_DxCrossRefBm573002926)). [Issue: CS-ACNS/3]
