TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Provide navigation and surveillance information needed for flight guidance, situational awareness and airspace operation.
What belongs here
- Air-data systems
- Inertial reference systems
- Radio navigation receivers
- Global navigation satellite systems
- Weather radar
- Radio altimeters
- Traffic and terrain awareness
- Transponders and surveillance interfaces
What users may see
Navigation displays, sensor-source flags, position or alignment status, weather and terrain imagery, traffic symbols, altitude or speed disagreement and system fault messages are typical.
What technicians commonly evaluate
Sensor accuracy, antenna and radome condition, alignment, database currency, software/configuration, pitot-static integrity, interference and required operational tests are common concerns.
