2. The Wing There are two types of wing configurations, they are: • Monoplanes • those that have one wing • Biplanes • those with two wings

3. Wing Positioning • High Wing on the top of the fuselage • Mid Wing in the middle of the fuselage • Low Wing on the bottom of the fuselage

4. Internal Construction Of The Wing • Spars • they are the main members of the wings and run the length of the wing from wing root to wing tip. The spars are intended to stiffen the wing against torsion or twisting.

5. Internal Construction Of The Wing • Ribs • they run from the leading to the trailing edge. Their purpose is to give the wing its framework to which the covering is fastened.

6. Internal Construction Of The Wing • Compression Struts • usually steel tubes spaced at regular intervals between the front and rear spars intended to take compression loads.

7. Internal Construction Of The Wing • Drag and Anti Drag Wires • run diagonally from front to the rear spars. These wires take drag loads and anti-drag loads, as their names imply.

8. Internal Construction Of The Wing • Ailerons • a moveable section attached to the trailing edge of the wing located towards the wing tip. As one moves downward, the opposite aileron moves upward.

9. Internal Construction Of The Wing • Flaps • a moveable section located next to the ailerons located towards the wing root. • Wing Span • the maximum distance from wing tip to wing tip

10. Internal Construction Of The Wing • Chord • an imaginary straight line joining the leading edge to the trailing edge of the wing.

11. Struts Extend out from the fuselage and attach to the wing, for support. Engine Cowl A protective housing for the engines. It streamlines the front of the aircraft to reduce drag. It ducts air around the engine for cooling.

23. Undercarriage or Landing Gear The function of the landing gear: • To absorb the shock of landing • To support the weight of the airplane and enable it to move on the ground. Landing gear may be: • Fixed • Retractable (which provides more streamlining)

24. Undercarriage or Landing Gear The landing gear may be: • Tricycle, or • Tail wheel configuration

25. Propulsion System The propulsion system of a modern general aviation airplane is generally a gasoline powered, air cooled, internal combustion engine that drives a 2 or 3 bladed propeller.

26. Equipment, Radios, Instruments • All instruments, radios, and other various equipment are located inside the cockpit. • A radio which enables contact with the ground, ATC, and other aircraft. • Instruments panel (airspeed indicator, altimeter, compass, etc) • ELT (Emergency Locator Transmitter)

38. Theory of Flight Parts of the Airplane Congratulations!! You have now completed the Parts of the Airplane lesson of the Theory of Flight Module. Of course, this lesson is always available to you for future reference if required. You are now ready to move along to the next Theory of Flight lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam. Good Luck!
