Purpose

The purpose of this Request for Support message (RFS) is to gather instances of operator errors relating to Precision Area Navigation (P-RNAV) STARs, transitions and SIDs that can inform the hazard analyses needed to support the development of local Safety Cases for the introduction of P-RNAV operations. This will ensure the appropriate mitigations are put in place.

Synopsis

Evidence considered so far has shown that operator errors (such as aircraft flying the wrong P-RNAV SID) dominate the occurrence reports within National and European (e.g. EVAIR) databases. This RFS seeks further experiences (e.g. identified hazards, reported/recorded deviations, corrective actions, mitigations, best practices etc.) from ANSPs and Aircraft Operators.

Regulatory Requirements & Guidance

Overall, it is expected that P-RNAV operations will be acceptably safe subject to the implementation being undertaken with due reference to the following:
