Avionics – Engine Monitoring Instruments
The 90090004-02 Fuel Pressure Ammeter is a dual-purpose analog instrument that displays fuel pressure and electrical current (amperage) data. This instrument is essential for ensuring safe and efficient fuel delivery and electrical system performance in turbine-powered helicopters. Monitoring these parameters in real time allows pilots and technicians to detect abnormal conditions that could impact engine reliability or flight safety.
Applications:
- Commonly installed in Bell 206, Bell 407, and other light turbine helicopters
- Used across a wide range of mission types including EMS, law enforcement, utility operations, and training aircraft
- Integrated within the engine instrument cluster on the pilot’s main instrument panel
