Aircraft controls and Structure Flashcards
What does the elevator alter
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
What does the rudder change
The aircraft rotates on the vertical axis(yaw)
FAA-8083-31 VOL 1 1-24
What does pulling or pushing the yoke forward or aft do
Changes the elevator causing nose pitch up or down
FAA-8083-31 VOL 1 1-27
What happens when the right pedal is pushed forward
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
The stress that resists a force that tends to pull apart
Tension
FAA-8083-31 VOL 1 4-2
The stress that resists a crushing force, tends to shorten or squeeze aircraft parts
Compression
FAA-8083-31 VOL 1 4-2
The stress that resists the force tending to cause one layer of material to slide over an adjacent layer
Shear
FAA-8083-31 VOL 1 4-2
The stress that resists the force that the rivet or bolt places on the hole.
Bearing
FAA-8083-31 VOL 1 4-2
The stress that produces twisting
Torsion
FAA-8083-31 VOL 1 4-3
Is a combination of compression and tension
Bending
FAA-8083-31 VOL 1 4-4
What axis does the ailerons control
Longitudinal axis
roll
FAA-8083-31 VOL 1 1-24
What happens when moving the control column aft
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
What happens when moving the control column forward
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.
