|
1. Forward section- includes the flight station.
2. Mid body section- the midsection of the aircraft. 3. Aft fuselage section- includes the tail cone. |
|
|
Describe the center wing
|
built as an integral part of the fuselage. It consists of a box-type beam, which is an assembly of the front and rear spar, top and bottom skin panel, and ribs. The spar is130 inches form BL56L to BL56R. After the structure assembly is completed, the box beam is sealed to form auxiliary fuel tanks.
|
|
|
Describe the left/right wing outer panel
|
consists of wings flaps, leading and trailing edge, wingtips, ailerons, and engine nacelles.
|
|
|
What is the function of the horizontal stabilizer?
|
(Longitudinal Stability) Provides stability of the aircraft about the lateral axis. This is the base in which the elevators are attached.
|
|
|
What is the function of the vertical stabilizer?
|
(Directional stability) maintains the stability of the aircraft about its vertical axis. Serves as a base to which the rudder is attached.
|
|
|
What is the function of the flaps?
|
Powered by the combined No.1 and No. 2 hydraulic systems, the wings are of a high- lift fowler type. This type of flap uses a combination of aft movement to increase the wing area, and a drooping (downward) movement to change the airfoil section.
|
|
|
What is the function of the ailerons?
|
Controls roll.
The ailerons are interconnected in the control system and work simultaneously, but in opposite directions to one another. As one aileron moves downward to increase lift on its side of the fuselage, the ailerons on the opposite side of the fuselage move upward to decrease lift. This opposing action allows more lift to be produced by the wing on one side of the fuselage than on the other side. |
|
|
What is the function of the rudder?
|
Used to move the aircraft about the vertical axis.
If the pilot moves the rudder to the right, the aircraft turns to the right; if the rudder is moved to the left, the aircraft turns to the left. |
|
|
What is the function of the elevators?
|
Controls pitch.
Raising the elevators causes the aircraft to climb. Lowering the elevators causes it to dive or descend. |
|
|
What is the function of the trim tabs?
|
enable the pilot to neutralize any unbalanced condition that might exist during flight, without exerting any pressure on the control stick or rudder pedals.
Each trim tab is hinged to its parent control surface, but is operated independently by a separate control. |
|
|
What is the function of the landing gear struts?
|
Absorbs the shock that otherwise would be sustained by the aircraft structure during takeoff and taxiing, and landing.

Hydraulic pressure from this pump is used to assist in operation of the wing flaps, bomb bay doors, ailerons, rudder, and elevators booster units, all of which receive pressure from both systems. This system must be refilled if it falls below one quart. |

|
|
What is the function of the engine driver compressors (EDC)?
|
The normal mode of operation of the air conditioning and pressurization system employs two engine driven compressors mounted on engine No.2 and 3. Heated, compressed air from the EDCis ducted through two-air cycle cooling units in the nose wheel well and then into the flight station and cabin. Air is drawn through the aircraft by the cabin exhaust fan and ducted overboard through the outflow valve, which controls pressurization.
