Symptômes A/P en vol — pitch mort, hardover aileron, pas de capture LOC. Capacité : dual Autoland ; ≥1 A/P RVSM.In-flight A/P symptoms — dead pitch, aileron hardover, no LOC capture. Capability: dual Autoland; ≥1 A/P RVSM.
ObjectifObjective
Diagnostiquer setup vs Pitch Transducer vs ARINC/FCC ; changer de canal avant d’insister — Urgence = hub QRH.Diagnose setup vs Pitch Transducer vs ARINC/FCC; change channel before insisting — Emergency = QRH hub.

Si A/P se déconnecte en approche : NNC existe — ouvrir hub Urgence. Ici = diagnostic teaching.If A/P disconnects on approach: NNC exists — open Emergency hub. Here = diagnostic teaching.
