F-35 Phase 3 EAWSDiscuss the hydraulic system of the F-35C. - ANS-Not centralized due to Electro
Hydrostatic Actuating System
Explain the use of arresting hook. - ANS-Used in flight deck operations and in
emergency situations.
Explain how the MLG brakes are operated. - ANS-Independently with dual redundant
brake position sensors.
Discuss the purpose of the nose wheel steering. - ANS-Assist in giving the aircraft
directional control during taxiing and takeoff procedure.
Describe what the nose landing gear strut assembly provides. - ANS-Landing, take-off,
taxi energy absorption and tire/runway compliance.
Discuss the design of the landing gear subsystem. - ANS-Tricycle design consists of
main and nose landing gear extension & retraction, wheel & brakes, nose wheel
steering, position & warning and arresting gear.
Discuss what flight control surface is the primary means of controlling the yaw. -
ANS-Rudder

Explain the purpose of the launch bar. - ANS-Engages the catapult, applying tow forces
to the aircraft for launchj.
Describe the location of the launch bar. - ANS-Forward side of NLG shock strut.
Define LEF. - ANS-Leading Edge Flap.
Explain the purpose of the landing gear safety pins. - ANS-Secure the nose and the
main landing gear in a down position preventing gear retraction while on deck.
Define FCS. - ANS-Flight Control System.
Explain the pilot control movement of the rudders. - ANS-Controlled by the pedals
instead of at the stick
How many chamber does the NLG shock strut have? - ANS-Dual Chamber.
Explain why the hydraulic systems are decentralized. - ANS-Due to EHAS.
What PPE is used when handling broken composite materials? - ANS--Respirator

2122, 2332, 2336, 2348, 2351
Describe the flight control surfaces that shorten take-off and landing distances. -
ANS-Leading Edge flaps lower the stall speeds and increase the drag.
, Describe the location of the brakes on the F-35C. - ANS-located in the MLG
Explain why the anti-skid system is combined with the normal system? - ANS-To
prevent wheel skid.
Explain the function of the wings and their purpose for the aircraft. - ANS-Provide lift for
the aircraft, store fuel, house leading edge flap, trailing edge flap and ailerons.
The LO weapon system gives the aircraft the ability to reduce what 4 characteristics? -
ANS-Radar, thermal, acoustic, visual detection.

defect data, maintainer log information, aircraft tail number defect description, location &
orientation, repair information.
Define LO3M. - ANS-Low Observable Maintenance Management Module.
Describe the purpose of LO3M. - ANS-Support flight operations by displaying the
aircraft health/status and recommending LO maintenance tasks be performed based on
a/c signature status and mission requirements.
Describe what maintenance facilities/hangars are required to perform Lo repairs. -
ANS-None.
Define MFE. - ANS-Maintainer Fabricated Enclosure.
