Study Notes
Aircraft Systems
Flight Control Systems
- Aircraft motion is defined by translational motion and rotational motion around a fixed set of axes (pitch, roll, and yaw)
- Primary flight control systems consist of ailerons, elevator, and rudder, which are attached to the airframe on hinges or tracks to deflect the air stream and generate an unbalanced force to rotate the plane
- Secondary flight controls improve aircraft performance characteristics or relieve excessive control loading, and include high lift devices, flight spoilers, and trim systems
Engine Control Systems
- Aircraft engine controls allow the pilot to control and monitor the operation of the powerplant
- In fixed-pitch propeller aircraft, propeller rotational speed depends on airspeed and loading, and the pilot adjusts the throttle/power lever to maintain desired constant speed
- In jet aircraft, FADEC (Full Authority Digital Engine Control) employs a digital computer to control all aspects of engine performance
- FADEC replaces analog electronic controls and is used in modern commercial and military aircraft
Fuel Systems
- Modern aircraft fuel management systems may include fuel pressurization, engine feed, fuel transfer, refuel/defuel, fuel storage, vent systems, use of fuel as heat sink, and fuel jettison
- Fuel systems vary from aircraft to aircraft, and the storage and assured supply of fuel during flight are critical issues
- Typical fuel system components include filters, drains, fuel vents, and aerial refueling systems
Hydraulic Systems
- Most aircraft today require hydraulic power for various tasks
- Hydraulic systems are used to power various aircraft functions, including landing gear, brakes, and flight control systems
