AMC1Â ACNS.E.TAWS.040Â 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,
âmisleading informationâ is considered to be an incorrect depiction of the
terrain threat relative to the aircraft under alert conditions.
