Block 3 - EA-18G Airframes Fundamentals Flashcards
State the purpose of the Hydraulic Fluid Contamination Analysis
Aids in determining fluid containment level, ensuring high level of fluid purity on Class 5 aircraft and Class 3 GSE
State the purpose of a tactical paint scheme
Lessen the probability of visual and photographic detection
State the purpose of the pubs listed in NAVAIR 01-1A-509, and NAVAIR A1-F18EF-IETM
NAVAIR 01-1A-509 - Provides info on materials and procedures to prevent, control, and repair corrosion damage to aircraft and avionics on land or on sea
NAVAIR A1-F18EF-IETM - Provides info to support the diagnostics, maintenance and repair of the EA-18G and F/A-19E/F aircraft systems
State the three modes of wheel brake operation
- Normal
- Emergency
- Parking
Discuss the purpose of the composite airframes material
To limit weight, increase strength and decrease effect of corrosion attack
What are the three types of repair?
- Temporary
- One Time Flight
- Permanent
What is Temporary Repair?
Simple and practical as possile, normally restores full load carrying capabilities allowing aircraft to be flown until permanent repair can be made
What is One Time Flight Repair?
Made to restore limited load carrying requirement to allow and aircraft to be flown to a repair station for permanent repairs
What is Permanent Repair?
Meets or exceeds strength of original structure or component with no adverse affects on structural integrity, fatigue life, safety or flying characteristics
What are Ailerons and what do they do?
In flight - Commanded asymmetrically to produce ROLL MOTION;
During takeoff/landing - deflect symmetically with the trailing edge flaps up to 45 degrees
Located on the outboard trailing edge of each wing
What are Leading Edge flaps and what do they do?
In flight - deflect asymmetrically to aid ailerons in producing ROLL MOTION
During takeoff/landing the leading edge flaps deflect symmetrically to change LIFT
Located on the inboard and outboard edge of each wing.
What are the Trailing Edge flaps and what do they do?
In flight - Independently defelect asymmetrically to aid the ailerons in producing roll motion
During takeoff/landing flaps deflect asymmetrically to change lift
Located on trailing edge of each wing
What are Stabilators and what do they do?
Deflect symmetrically to produce PITCH MOTION and asymmetrically to produce ROLL MOTION, also provides pitch compensation during selection of the lex spoilers
Located on either side of the tail of the aircraft
What are Rudders and what do they do?
Toe-in - Increase lift and improve stability (AOA LESS than 8 degrees)
Toe-out - Improve stability (AOA MORE than 8 degrees)
In-flight commanded symmetrically to produce yaw
What are LEX Spoilers and what do they do?
Provides speed brake when commanded at speeds up to Mach 1.5
