What is the F/A-18 structure and surface contain? correct answersgraphic and carbon/epoxy composite materials
What is a safety hazard while dealing with fiber correct answersIt can be embedded into exposed skin and become difficult to remove.
What precautions must be observed when handling these materials? correct answerswearing a respirator and goggles and wearing close weave cotton gloves when handling exposed or damaged material.
What are the areas to avoid stepping on? correct answersLeading edge flaps, trailing edge flaps, horizontal stabilizers, ailerons, and radome surfaces.
Explain the purpose of the landing gear safety pins? correct answerssafety mechanism to prevent the landing gear from retracting.
Before towing an aircraft, what access doors should be installed? correct answersMinimum structural access door must be installed, Radome must be closed and secure, and ensure doors 68L/R are closed or removed.
What are the three types of repair? correct answersTemporary repair
One Time Flight repair
Permanent Repair
Where is the launch bar located and function? correct answersLocated: attached to the nose landing gear.
Function: provides a means of steering the a/c during carrier deck tracking and engages the catapult, applying catapult tow forces to the a/c. What does the Wheel Brake provide? correct answersprovides the pilot the ability to brake the wheels individually.
What does the Arresting Hook do? correct answers-hydraulically controlled arm
-To catch the wire on a carrier landing.
What does the Hydraulic system contain? correct answersAccumulator, Hydraulic reservoir, lines, and multiple valves.
What does the Hydraulic system 1 provide? correct answersto the primary flight controls either as a primary or backup source.
What does the Hydraulic system 2 provide? correct answers-to the primary flight controls either as a primary or backup source. - to all other non-flight control systems.
What do switching valves do? correct answersAllow backup hydraulic pressure to replace the primary hydraulic pressure when primary hydraulic pressure fails. If primary hydraulic is restored, the switching valve shifts to normal operating position.
What type of engines are used on the F/A-18 A-D? correct answersF404-GE-400 or F404-GE-402
low bypass, axial flow, dual-spool, turbofan engine of Modular construction with a afterburner.
What is the Ignition system? correct answersAutomatic, intermittent duty, AC powered, Capacitor discharge system.
How is the Ignition system circuitry? correct answersSelf-contained on the engine, requiring no a/c electrical power for operation. Remains energized until N2 rpm is 54% or greater or the throttle is retarded below idle.
What is the Ignition system made up of? correct answersAlternator, FADEC or ECA, engine fuel control, ignition exciter, main igniter, AB igniter, AB flame sensor, two fan speed transmitters and thermocouple harnesses. How is lubrication accomplished? correct answersThrough a self-contained recirculation, dry sump requiring no external connections or inputs. Provides lubrication/cooling to the required bearings and gears.
What is the Variable Exhaust Nozzle (VEN) system? correct answersIs a cam and link-positioned hinged-
flap, convergent-divergent nozzle, mounted to the aft end of the afterburner case.
How is the VEN operated? correct answersit is hydraulically (fuel) operated, electrically controlled series of actuators, synchronizing shafts, links, flaps, seals, providing a controlled throat area for the exhaust gasses form the turbine and AB.
What does the VEN system provide? correct answersrequired thrust and fuel efficiencies while maintaining exhaust gas temperature (T5)
What does the Anti-Icing system provide? correct answersprevents build-up of ice on air inlet hardware; the pilot manually activated the anti-icing system, signaling the FADEC/ECA to activate the anti-icing valve
What does the Full Authority Digital Engine Control (FADEC) or ECA on F404-GE-400/402 do? correct answersIt receives a/c and engine sensor information and determines the appropriate engine scheduling
to operate the engine in all areas of the flight envelope.
What are the major components of the fuel system? correct answersThe main fuel control, afterburner (AB) fuel control, throttle system, fuel cooling and fuel storage.
What is the main fuel control function? correct answersIs to govern the correct main fuel flow to the combustion section controlling engine starting and operation from IDLE through MIL.
Where is the FADEC/ ECA located and function? correct answersLocation: mounted on each engine.
Function: provides full control of the engines based on throttle lever position.
Where are the fuel storage located? correct answers4 internal tanks
