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)

 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

A protective housing for the engines. It streamlines the front of the aircraft to reduce drag. It ducts air around the engine for cooling.

Engine Cowl

Extend out from the fuselage and attach to the wing, for support.

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)

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!
