TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Generation, conversion, distribution and protection of electrical power.
What belongs here
- Engine or APU generators
- External power interface
- Batteries and chargers
- Transformer rectifier units
- Inverters and converters
- Busbars, contactors and relays
