Study Notes
Electrical System Overview
- Aircraft utilizes a 14-volt direct-current electrical system with a single-wire configuration.
- The system is designed with a negative ground to avoid electrical hazards and ensure proper grounding.
Power Sources
- A 12-volt battery serves dual purposes:
- Starts the engine.
- Provides backup power in case of alternator failure.
- The main power supply in-flight is from an engine-driven alternator, which recharges the battery during operation.
Voltage Regulation
- A voltage regulator is integral to the system, maintaining the battery charge and preventing over-voltage conditions.
External Power Options
- An external power source receptacle is available as optional equipment, facilitating:
- Battery assistance for engine starting.
- Ground operation power without relying on the battery alone.
