HOW THE TECHNICAL COVERAGE IS ORGANISED
The systems dossier treats the selected airframe and propulsion configuration before following the electrical, pneumatic, hydraulic, fuel, sensor and control chains. The engineering reference distinguishes the currently offered aircraft from the larger set of certified Airbus variants. Engine model names, wingtip options and additional-tank configuration must agree with the loaded aircraft. The exact inventory is recorded in the dedicated variant discussion rather than inferred from an exterior photograph. [70, Current livery configuration options]
The advanced FMGS section follows the information through entry, validation, trajectory construction, prediction and guidance. A temporary revision, an active route, a secondary plan and a navigation database are separate states. The appropriate recovery action depends on which state is wrong. Work through the related chapter and its readback before attempting to solve the problem with a broader reset. [66, Flight-plan management; temporary and secondary plans]
The operational section then connects the aircraft state with performance, guidance, weather, normal operation, abnormal assessment and the Fenix software environment. The original normal checklists remain the compact sequence. The extended material supports understanding, preparation and debrief, while a current installed procedure supplies the applicable failure sequence.
