Define the safety diamond area
Lines connecting the aircrafts nose, wingtips, and aft of the tail
Primary material used for the nose radome
Mostly fiberglass
Primary material used for the tail fin
Mostly aluminum
Elevators are a graphite composite
What are the primary flight controls?
Ailerons
Elevators
Rudder
Aileron
Controls flight attitude around the longitudinal axis (Roll).
Elevators
Made of a graphite composite. Controls pitch attitude around the lateral axis (Pitch).
Rudder
Made of a graphite composite. Controls flight attitude around the vertical axis (Yaw).
What are the secondary flight controls?
Leading edge devices
Trailing edge flaps
Spoiler and speed brakes
Horizontal stab
Leading edge devices
Flaps and slats increase wing area and wing camber. Increase lift for takeoff and landing.
Trailing edge flaps
Increase wing area and camber. Increase lift for takeoff and landing.
Spoiler and speed brake
Help ailerons control roll. supply speed brakes to reduce lift and increase drag during landing.
How many spoilers are there?
6 on each wing
1 inboard of each engine strut
5 outboard of each engine strut
Horizontal stab
Made of mostly aluminum. Controls pitch trim of aircraft about the lateral axis.
What indication is given by the Stall Warning System?
Shakes control column when the aircraft is close to a stall.
What is the purpose of the Antiskid/Auto brake system?
-Controls brake system to prevent wheel skids
-Supplies metered brake pressure to stop after landing or rejected takeoff (RTO)
What method is used to de-ice the Raked Wingtips?
-Uses electro mechanical expulsive de-icing system which uses electronically powered actuators which gives a pulse to the leading edge and shatter the accrued ice.
Purpose of the Flight Deck Window Heat
Prevents
-Ice formation on windows
-Fog of windows
-Improves window impact strength
Purpose of the Section 48 Access and Blowout Door
-Access to 48 components
-Has spring-loaded latch system
-Protects empennage structure if aft pressure bulkhead fails
-Door latch will open if a load of 52-68 lbs is put on the inside of the door
