Aircraft controls and Structure

Question 1

What does the elevator alter

Answer 1

Aircraft pitch, which the attitude about the horizontal or lateral axis causing the nose to pitch up or down

FAA-8083-31 VOL 1 1-24

Question 2

What does the rudder change

Answer 2

The aircraft rotates on the vertical axis(yaw)

FAA-8083-31 VOL 1 1-24

Question 3

What does pulling or pushing the yoke forward or aft do

Answer 3

Changes the elevator causing nose pitch up or down

FAA-8083-31 VOL 1 1-27

Question 4

What happens when the right pedal is pushed forward

Answer 4

Deflects the rudder to the right which moves the nose of the aircraft to the right along the yaw

FAA-8083-31 VOL 1 1-27

Question 5

The stress that resists a force that tends to pull apart

Answer 5

Tension

FAA-8083-31 VOL 1 4-2

Question 6

The stress that resists a crushing force, tends to shorten or squeeze aircraft parts

Answer 6

Compression

FAA-8083-31 VOL 1 4-2

Question 7

The stress that resists the force tending to cause one layer of material to slide over an adjacent layer

Answer 7

Shear

FAA-8083-31 VOL 1 4-2

Question 8

The stress that resists the force that the rivet or bolt places on the hole.

Answer 8

Bearing

FAA-8083-31 VOL 1 4-2

Question 9

The stress that produces twisting

Answer 9

Torsion

FAA-8083-31 VOL 1 4-3

Question 10

Is a combination of compression and tension

Answer 10

Bending

FAA-8083-31 VOL 1 4-4

Question 11

What axis does the ailerons control

Answer 11

Longitudinal axis
roll

FAA-8083-31 VOL 1 1-24

Question 12

What happens when moving the control column aft

Answer 12

Aft movement of the control column deflects the trailing edge of the elevator surface up. This is usually referred to as the up-elevator position. The up-elevator position decreases the camber of the elevator and creates a downward aerodynamic force, which is greater than the normal tail-down force that exists in straight-and- level flight. The overall effect causes the tail of the aircraft to move down and the nose to pitch up.

FAA 6-5

Question 13

What happens when moving the control column forward

Answer 13

Moving the control column forward has the opposite effect. In this case, elevator camber increases, creating more lift (less tail-down force) on the horizontal stabilizer/elevator. This moves the tail upward and pitches the nose down. Again, the pitching moment occurs about the CG.
