AMC1 ACNS.E.TAWS.040 Integrity ED Decision 2022/008/R A functional hazard assessment (FHA) applied to the specific design should be included in the certification dossier of the system. Elsewhere, failure conditions that result in false terrain warning and caution alerts, a non-annunciated loss of function, or the presentation of misleading information, should be considered major failure conditions. Note: In this case, ‘misleading information’ is considered to be an incorrect depiction of the terrain threat relative to the aircraft under alert conditions. [Issue: CS-ACNS/4]
