AMC1 ACNS.C.PBN.2130 Alerting
associated with degradation of navigation
ED Decision 2019/011/R
The alerting requirement is satisfied by installation of equipment with an ETSO authorisation against ETSO-C115d or ETSO-C146c, provided that the applicant ensures that the alert is appropriately indicated in the flight crew’s optimum field of view, and assess any processing delays caused by the aircraft flight deck alerting system.
Subject to EASA’s agreement, display of the alert in the flight crew’s maximum field of view may be accepted. The applicant should support the deviation by providing a human factor and workload assessment.
Note: The alleviation provided above is intended to address particular concerns on smaller aircraft, for example, CS-23, Level 1, 2, and 3 aircraft.
