Aircraft Familiarization

Question 1

Ailerons

Answer 1

Hinged section of the outboard portion of the wings which act in tandem to one another. The movement of the ailerons are allowing the aircraft to turn. By turning the yoke, one aileron on one wingtip will go up and opposite one will go down. This causes one wing to go up and the other one to go down, the aircraft will roll in the direction selected.

Question 2

Control Column (Yoke)

Answer 2

Moving the control column forward and backward, the pilot control the elevators, thereby controlling the pitch. On top of the control column is a wheel connected to the ailerons and spoilers to control roll. At the pilot feet are two pedal controlling the rudder which controls yaw.

Question 3

Drag

Answer 3

Resistance of the aircraft to moving through the air. This resistance increase with the use of flaps and leading edge devices, and increase greatly with the use of spoilers, fine pitch of the propellers ans extension of the landing gear.

Question 4

Elevators

Answer 4

Attached movable surfaces attached to the trailing edge of the horizontal stabilizer which control the aircraft’s pitch, allowing the aircraft to climb or descend.

Question 5

Engines

Answer 5

Develop power by burning fuel to move aircraft forward and reverse thrust for additional breaking effect. They drive generators to provide power to the aircraft electrical system, drive pumps for the hydraulic system, produce bleed air for aircraft pressurization and de-icing system.

Question 6

Flaps

Answer 6

Attached extended surfaces on the trailing edges of the main spar (wings) that extend to increase lift when the aircraft flies at lower speed. An aircraft can land without flaps but the landing will be considered non-normal and occurs at higher speed than normal. Emergency vehicles may attend even if no emergency is declared.

Question 7

Leading edge

Answer 7

The front part of the wing

Question 8

Rudder

Answer 8

Comprised of two attached panel surfaces on the training edge of the vertical stabilizer. The rudder moves left and right to affect the yaw change of the aircraft in the opposite directions (Right rudder pedal, right rudder, tail moves left and nose moves right).

Question 9

Tail skeg

Answer 9

Triangular structural brace where the front edge of the tail meets the top of the fuselage, on the Q400, the fixed ELT is located in the tail skeg.

Question 10

Trailing edge

Answer 10

The back part of the wing.

Question 11

Wing root

Answer 11

Portion of the wing that meets the fuselage of the aircraft.

Question 12

Wing tip

Answer 12

The outer-most part of the wing

Question 13

Winglet

Answer 13

The upwardly formed end at the wing tip which increases the aerodynamic efficiency of the wing and results in reduced fuel burn. On Boeing 737-700 and 800 but not Q400.

Question 14

Wings

Answer 14

Airfoil structures which develop lift to carry the aircraft into the air.
