THE PRO COMPANION: CONNECT THE AIRCRAFT, THE PROGRAMME AND THE EVIDENCE
This edition develops the original guide into a professional reference for the Fenix A319, A320 and A321. The Frankfurt–Heathrow flight supplies a consistent working case. The systems dossier and advanced FMGS chapters explain the underlying architecture, configuration differences and the consequences of decisions made during that flight.
Use the aircraft and software applicability with each explanation. The source library includes several Airbus generations and FM software standards. A documented real-aircraft capability and a verified Fenix implementation are recorded separately; a historical option is never promoted to a current simulator feature through resemblance alone.
The concise normal checklists remain unchanged. The practical sections retain the established action-and-readback steps, while the advanced chapters extend the reasoning, branch cases and programming detail. Click a numbered citation for the full reference. PDF verification-card ticks can be saved in the PDF; the native EFB edition uses its checklist interface.
