Aircraft Systems

Engine Starting System

Propulsion

Pneumatic or electric system that spins the engine core to self-sustaining RPM, typically using APU bleed air, ground air cart, or electric starter-generators.

Thrust Reverser System

Propulsion

Mechanism that redirects engine exhaust forward upon landing to assist with deceleration, available as cascade, clamshell, or target-door types.

Engine Bleed Air System

Propulsion

System that extracts compressed air from engine compressor stages for cabin pressurization, anti-icing, engine start, and hydraulic reservoir pressurization.

FADEC System

Propulsion

Full Authority Digital Engine Control — computerized system managing all aspects of engine performance from start to shutdown with no manual override required.

Aircraft Fuel System

Propulsion

Integrated system of tanks, pumps, valves, and crossfeed lines that stores and delivers fuel while managing center of gravity through fuel sequencing.

Engine Oil System

Propulsion

Lubrication and cooling circuit circulating synthetic oil through engine bearings, gearboxes, and accessory drives while filtering contaminants.

Engine Fire Detection and Suppression

Propulsion

Dual-loop sensing system using continuous element detectors in engine nacelle and APU bays, paired with Halon/HFC fire extinguisher bottles.

Nacelle and Inlet System

Propulsion

Aerodynamic structure housing the engine that conditions airflow, provides acoustic treatment, and houses thrust reversers and fire protection.

Auxiliary Power Unit (APU)

Propulsion

Small turbine engine in the tail section providing electrical power and pneumatic air for engine starting and ground operations without main engines running.

Engine Vibration Monitoring System

Propulsion

Real-time monitoring using accelerometers to detect abnormal vibration indicating bearing wear, blade damage, or rotor imbalance.
