Front 5

e.What is a Wing?

Back 5

Provides lift for the A/C, stores fuel, houses LEF's, TEF's and Ailerons, outboard section folds for carrier operation, allows for attachment of non jettison able pylons for weapons/fuel stores.

Front 6

f.What is a Leading Edge Extension?

Back 6

Provides added lift at high angles of attack.
"Mounted on either side of the Forward Fuselage they are an extension of the wing leading edge."

Front 7

"Flight Control Surfaces"
a.Ailerons?

Back 7

During flight, the ailerons are commanded asymmetrically to produce roll motion, during takeoff and landing (with flaps switch set to half or full) they deflect symmetrically with the trailing edge flaps up to 42 degrees, trailing edge flap down to change lift.
"The ailerons are located on the outboard trailing edge of each wing."

Front 8

b.Leading Edge Flaps?

Back 8

When taking off or landing the leading edge flaps deflect symmetrically to change lift. During flight they deflect asymmetrically to aid the ailerons in producing roll motion. The leading edge flaps are located on the inboard and outboard leading edge of each wing.

Front 9

c. Trailing Edge Flaps?

Back 9

When taking off or landing the leading edge flaps deflect symmetrically to change lift. During flight they independently deflect asymmetrically to aid the the ailerons in producing roll motion. The trailing edge flaps are located on the trailing edge of each wing.

Front 10

d. Stabilizers?

Back 10

The stabilizers deflect symmetrically to produce pitch motion and asymmetrically to produce roll motion. The stabilizers are located on either side of the tail of the A/C.

Front 11

e. Rudders?

Back 11

During takeoff or landing when the AOA is less than 8 degrees the rudders toe-in to increase lift and improve stability, when AOA is more than 8 degrees the rudders toe-out to improve stability.
In flight the rudders are commanded symmetrically to produce yaw motion.
"The rudders are located on the rear of each vertical stabilizer."

Front 12

f. Speed Brake?

Back 12

Under certain conditions the speed brake may be extended into the air stream creating drag and slowing the A/C's airspeed.
"The speed brake is located on top of the Aft Fuselage between the vertical stabilizers."

Front 13

"Hydraulics"
a.Hydraulic System 1?

Back 13

Provides hydraulic fluid pressure to the primary flight controls either as a primary or back-up source.
System contains pump manifold, pump reservoir, filter unit, case drain filter, oil fuel heat exchange, and related indicators.

Front 14

b.Hydraulic System 2?

Back 14

Same as 1.
The system also supplies pressure to all other non-flight control systems.

Front 15

c. Auxilliary Power Unit Accumulator?

Back 15

Gas charge cylinder provides required fluid pressure to the APU start motor and emergency hydraulic systems.

Front 16

d. Switching Valves?

Back 16

Each switching valve allows backup hydraulic pressure to replace the primary hydraulic pressure, if the primary hydraulic pressure fails.
If primary hydraulic is restored, the switching valve shifts to normal operating position.

Front 17

"Landing Gear"
a. Nose Landing Gear?

Back 17

Nose landing gear strut assembly provides landing, takeoff and taxi energy absorption, and tire/runway compliance. Located on the underside of the Forward Fuselage. Dual chamber design provides a smooth long strike during landing and catapult operations.

Front 18

b. Main Landing Gear?

Back 18

A lever design with a shock absorber.
Provides a stable platform for A/C carrier and shore based operations. Also absorbs the energy from ground loads during landing and taxi operations. Located on the underside of the Center Fuselage.

Front 19

c. Wheel Brakes?

Back 19

Located on the main landing gear wheels.
Provides pilot modulated individual wheel-controlled braking. An anti skid system is combined with the normal system to prevent wheel skid.

Front 20

d. Launch Bar?

Back 20

"Located on the forward side of the nose landing gear shock strut."
Provides a means of steering the A/C during carrier deck tracking and engages the catapult, applying catapult tow forces to the A/C.

Front 21

e. Arresting Hook?

Back 21

"Located on the underside of the aft fuselage."
A hydraulically controlled arm attached to the underside of the aft fuselage. A hook point is attached to the end of the arm. Provides a means of stopping the A/C where normal runway landings are not available.

Front 22

"Environmental Control Systems"
a. Bleed Air System?

Back 22

Engine bleed is extracted from the last compressor stage of both engines, regulated and routed to the air cycle air.

Front 23

b. Air Cycle Air Conditioning System?

Back 23

Cools and conditions hot bleed air for use in various A/C systems, such as fuel pressurization, canopy seal, anit-g, throttle boost, anti ice, rain removal, avionics and cabin cooling.

Front 24

c. Anti-Gravity System?

Back 24

Automatically regulates the air to the pilot's anti-g suit to increase pilot tolerance to high acceleration levels.
