BLOCK 1 - AIRFRAME Flashcards
Safety Diamond
Lines connecting the nose, wing tips, and tail extending out 5ft.
Flaps
Moveable flight control surfaces on the wings. Always verify clearance prior to operational flight
Areas of Corrosion
in box seam areas and around plates steel fasteners, unpainted surfaces actuating mechanics, painted surfaces chipped and peeled, skin seams, lap joints, areas where dirt/grime collect, rub strips, access doors, cowling areas and crevices due to moisture and cleansing compounds
What is Fuselage made up of?
Aluminum alloy, alloy steels, and stainless steel
Fuselage structure and what’s inside them?
Nose - radome and flight station
forward section - elec and galley
center midsection - passenger and seating
aft midsection - lavatory and baggage
Tail
What is Nose Radome made out of? Function?
Fiberglass honeycomb and houses avionics and it has conductors that minimizes lightning strikes.
Engine pylons location and function
between the engine nacelle and fuselage. Has cables for engines.
Purpose of Wings and where are they mounted through?
Provide primary lift for AC.
Mounted in the lower fuselage “Wing Box”.
Tail is made up of?
vertical and horizontal stabilizers.
Vertical stabilizer
Provides stability of vertical axis or directional stability. Also base for rudder.
Horizontal stabilizer
Provides stability of lateral axis or longitudinal stability. Also base for elevator
Control columns
Primary means for controlling a/c.
Provides fore and aft movement for longitudinal
lateral control (roll)
Rudder pedals location
Located on floorboard, pilots copilots feet..
Ailerons function and attached to?
Provides lateral control (roll),
attached to outboard trailing edge of the wings
Elevator function and attached to?
Provides longitudinal control (pitch),
attached to edge of horizontal stabilizer
Trim tabs location
They’re on the elevator and aileron surfaces.
Flaps provides what? and reduces what?
(Attached to wing edges) provide extra lift on takeoff and help reduce landing speed
Movable flight control surface on wings
How many Spoilers on each wings? Function?
- (2) flight and (1) ground (for landing) spoilers.
Struts
Absorb shock
How many Struts are there?
3 struts (two main and one nose)
How many nose wheels? Main wheels?
2 nose and 4 main wheels
Where is the brake assembly attached? What are they for?
Each main landing gear has a brake assembly to slow and stop AC.
Also prevent rolling when parked.
How are Landing gear doors operated?
Hydraulically.
How is Nose wheel steering controlled, powered and operated?
Electronically controlled, hydraulically powered and mechanically operated.
E - C
H - P
M - O
Hand wheel/ Rudder pedal can provide how many degrees of turning?
Hand wheel - 78 degrees L or R
Rudder pedal - 7 degrees L or R
Main door
Free falls and retracts hydraulically
Cargo door
Opens outward and upward Inflatable seal helps maintain pressure in cabin.
Baggage door
Opened from inside or outside, inward and upward
Emergency exits
One on each wing and one forward of the cargo door. Baggage and main door also used for emergency.
