Airbus A318 A319 A320 A321 Chapter 22 Auto Flight Aircraft Maintenance Manual
The Airbus A318 A319 A320 A321 Chapter 22 Auto Flight Aircraft Maintenance Manual – Revision 40 2012 is a detailed technical reference devoted to ATA Chapter 22 Auto Flight systems on the A318, A319, A320 and A321. Across 1278 pages, it documents system architecture, control laws, cockpit controls and indications, computer interfaces, component arrangements, operational logic, servicing, removal and installation tasks, adjustment and operational tests, and fault-isolation functions associated with the aircraft automatic flight systems.
The material extends well beyond a basic description of autopilot operation. It follows the interaction between the Automatic Flight System, Flight Management and Guidance Computers, Flight Augmentation Computers, Flight Control Unit, Multipurpose Control and Display Units, aircraft displays, engine interfaces and related control functions. Numerous figures, block diagrams, architecture drawings, control-law diagrams and component illustrations support the technical explanations and maintenance procedures.

Automatic Flight System Architecture and Guidance
A substantial part of this Airbus A318 A319 A320 A321 Auto Flight maintenance manual explains how the Automatic Flight System is arranged and interconnected. The general Auto Flight section includes AFS component layouts, computer locations, overall architecture, cockpit controls and indications, engine interconnections, FAC information displayed on the Primary Flight Display, flight-director symbols, flight-mode annunciation, navaid selection and flight-management information displays.
The Autopilot/Flight Director material develops this further with descriptions of AP/FD components and cockpit controls, flight-director orders, level-change operation and interfaces with the flight-control system. Separate illustrations and explanations address rudder, pitch, aileron, spoiler and nose-wheel control, while the manual also traces AP/FD information transmitted to the PFDs and the relationship between the FMGCs and display systems.

Taken as a whole, the manual gives maintenance personnel a system-level view of how automatic guidance, autothrust, flight augmentation and flight management functions are generated, monitored, displayed and tested. The descriptive sections explain the operating logic and interfaces, while the maintenance portions bring that information into practical use through component access, removal and installation, servicing, functional checks, AFS diagnostic routines and system operational testing.
Flight Management, Navigation and Performance Functions
The Flight Management System coverage is especially extensive. It documents general FMS architecture together with navigation, radio-navigation, lateral-guidance, weight and prediction/vertical-guidance architecture. The manual describes how lateral and vertical flight plans underpin navigation, guidance and performance calculations, and it follows the relationship between the FMGCs, MCDUs, PFDs, NDs, FCU and other aircraft systems.
Flight-plan and database material covers departure, arrival, approach and go-around segments; flight-plan initialization; secondary and temporary flight plans; lateral and vertical revision pages; wind entry; stored and new navaids, waypoints, runways and routes; holding patterns; and numerous MCDU page functions. Navigation material includes radio positions, FMGC position computation, localizer and position updating, navigation mode selection, IR alignment, coordinate entry, leg-transition types and lateral-path-error calculations.

Vertical and performance functions include flight phases, takeoff parameters, climb and descent predictions, altitude constraints, step climb, theoretical descent and approach profiles, speed-selection effects, fuel and weight displays, engine-out display functions and fuel predictions. This gives the A318 A319 A320 A321 Chapter 22 Auto Flight manual strong value for technicians who need to understand not merely an individual component but the information flow and functional relationships throughout the FMGS.
Maintenance, Component Replacement and System Testing
The manual contains practical component-maintenance tasks as well as descriptive material. Removal and installation procedures are provided for components including the rudder-trim control switch, RUD TRIM/RESET pushbutton switch, rudder-trim indicator, Flight Augmentation Computer, Flight Control Unit, Multipurpose Control and Display Unit and Flight Management and Guidance Computer. The MCDU section also includes a cleaning procedure.
Operational and adjustment/test material addresses numerous Auto Flight functions. Examples include tests of takeover and priority pushbuttons, autopilot disengagement and locking devices, vertical-speed and heading-hold modes, FCU lighting, FCU indicators and displays, altitude alert warning, FAC functions, rudder travel limiting, rudder trim, yaw damper and MCDU functions. The AFS test chapter explains computer safety-test information, discrete and ARINC input checks, plausibility testing, MCDU test reporting and troubleshooting information. LAND CAT III capability testing is also included as a dedicated section.
Fault Isolation and BITE Information
For troubleshooting work, Chapter 22 includes dedicated fault-isolation material rather than limiting the technician to system theory. The Fault Isolation Function section describes detection and analysis principles, FAC and FMGC BITE levels, report pages, LRU identification, ground scanning and examples of report utilization. The separate AFS Fault Isolation and AFS Test sections extend that workflow with system integrity testing after LRU replacement and test-result analysis through the MCDU.
This combination of functional diagrams, system logic and diagnostic information is particularly useful when a maintenance action requires understanding which computer or interface participates in a function before a component is removed or a test is run.
Instant PDF Maintenance Reference
The Airbus A318 A319 A320 A321 Chapter 22 Auto Flight Aircraft Maintenance Manual – Revision 40 2012 supports detailed work on autopilot and flight-director functions, autothrust, FAC-controlled augmentation functions, flight management and guidance, FCU and MCDU equipment, FMGC installations, system interfaces, operational tests and AFS fault-isolation tasks. Using the documented architecture, procedures, tests and control-system information helps technicians follow the specific Chapter 22 maintenance sequence rather than relying on generalized system descriptions. The manual is delivered as an instant PDF after purchase, with no physical shipping required; it can be opened on compatible computers, tablets or phones and printed as needed for workshop or reference use.
