TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Autopilot, flight director and automatic flight-control functions.
What belongs here
- Flight-control computers
- Flight director functions
- Autopilot servos or flight-control actuators
- Mode-control panel or flight-control unit
- Autothrust or autothrottle functions
- Guidance sensors and data interfaces
What users may see
Mode annunciations, engagement status, flight-director commands, autopilot or autothrust cautions and computer fault messages are central indications.
What technicians commonly evaluate
Correct sensor inputs, mode logic, rigging or actuator condition, data-bus integrity, software/configuration status and post-maintenance operational tests are important boundaries.
