Overview of Engine Instrument System

The engine instrument system provides critical information about the operational status of an aircraft engine.
It enables pilots and maintenance crews to monitor engine performance and detect malfunctions early.

Key Components

Indicators:
- Tachometer: Measures engine speed (RPM).
- Oil Pressure Gauge: Monitors oil pressure in the engine.
- Oil Temperature Gauge: Indicates oil temperature.
- Fuel Flow Indicator: Shows fuel consumption rate.
- Exhaust Gas Temperature (EGT) Gauge: Measures temperature of exhaust gases as an indicator of engine performance.
- Manifold Pressure Gauge: Indicates the pressure of the air-fuel mixture in the engine's intake manifold.
Warning Lights and Alarms:
- Alerts pilots to critical conditions (e.g., high temperature, low oil pressure).
- Ensures immediate attention to potential engine issues.
Data Processing Unit:
- Collects and processes data from various sensors.
- Displays real-time engine performance data on cockpit displays.

Types of Engine Instrument Systems

Analog Systems: Utilize traditional gauges with needle indicators.
