Which statement about elevators is correct?
Select one:
a.The elevator is used only to trim an aeroplane and is normally operated by a dedicated control wheel, which is usually situated close to the throttle.
b.The elevator is the primary control surface for control about the lateral axis and is operated by a forward or backward movement of the control wheel or stick.
c.The elevator is the primary control surface for control about the longitudinal axis and is operated by a forward or backward movement of the control wheel or stick.
d.The elevator is the primary control surface for control about the longitudinal axis and is operated by a left or right rotation of the control wheel.
b.The elevator is the primary control surface for control about the lateral axis and is operated by a forward or backward movement of the control wheel or stick.
When the rudder pedals are moved to cause a yaw to the left:
Select one
a.the right pedal is moved forward and the rudder moves to the right.
b.the left pedal is moved forward and the rudder moves to the right.
c.the left pedal is moved forward and the rudder moves to the left.
d.the right pedal is moved forward and the rudder moves to the left
c.the left pedal is moved forward and the rudder moves to the left.
If the nose of an aeroplane yaws left, this causes:
Select one
a.a roll to the left.
b.an increase in lift on the left wing.
c.a decrease in relative airspeed on the right wing.
d.a roll to the right.
a.a roll to the left.
Which of the following devices is used to provide aerodynamic balance?
Select one:
a.Mass balance fitted forward of the hinge line.
b.Trim tab.
c.Anti-balance tab.
d.Frise ailerons.
c.Anti-balance tab.
Left rudder pedal input will cause a:
Select one
a.yaw to the right and a roll to the left.
b.yaw to the left and a roll to the right.
c.yaw to the right and a roll to the right.
d.yaw to the left and a roll to the left.
d.yaw to the left and a roll to the left.
If the nose of an aeroplane yaws to the left, this causes:
Select one
a.an increase in lift on the left wing.
b.a roll to the right.
c.a roll to the left.
d.a decrease in relative airspeed on the right wing.
c.a roll to the left.
Yaw is followed by roll because the:
Select one
a.rolling motion generated by rudder deflection causes a speed increase of the outer wing which increases the lift on that wing so the aeroplane starts to roll in the direction of the turn.
b.rudder is located above the longitudinal axis and when it is deflected, it causes a rolling moment in the same direction as the yaw.
c.yawing motion generated by rudder deflection causes a speed increase of the outer wing, which increases the lift on that wing so that the aeroplane starts to roll in the same direction as the yaw.
d.yawing motion generated by rudder deflection causes a speed increase of the inner wing, which increase the lift on that wing so that the aeroplane starts to roll in the same direction as the yaw.
c.yawing motion generated by rudder deflection causes a speed increase of the outer wing, which increases the lift on that wing so that the aeroplane starts to roll in the same direction as the yaw.
When a turn is initiated, adverse yaw is:
Select one
a.the tendency of an aeroplane to yaw in the opposite direction of turn mainly due to the difference in aileron form drag.
b.the tendency of an aeroplane to yaw in the same direction of turn due to the different wing speeds.
c.the tendency of an aeroplane to yaw in the opposite direction of turn mainly due to the difference in induced drag on each wing.
d.a momentary yawing motion opposite to the turn due to an incorrect differential aileron movement.
c.the tendency of an aeroplane to yaw in the opposite direction of turn mainly due to the difference in induced drag on each wing.
Adverse yaw during a turn entry is caused by:
Select one
a.increased parasite drag on the raised wing and decreased parasite drag on the lowered wing.
b.decreased induced drag on the lowered wing and increased induced drag on the raised wing.
c.decreased induced drag on the raised wing and decreased induced drag on the lowered wing.
d.increased induced drag on the lowered wing and decreased induced drag on the raised wing.
b.decreased induced drag on the lowered wing and increased induced drag on the raised wing.
Directional control is achieved by:
Select one
a.the elevator, resulting in a motion around the lateral axis.
b.the rudder, resulting in a motion around the longitudinal axis.
c.the rudder, resulting in a motion around the normal axis.
d.the ailerons, resulting in a motion around the longitudinal axis.
c.the rudder, resulting in a motion around the normal axis.
The vertical fin of an aircraft is a symmetrical aerofoil. From the following, select a correct statement:
Select one
a.It can not provide lift, only drag.
b.It could stall if the fin angle of attack is too great.
c.It will provide an aerodynamic force only when the rudder is moved.
d.It will produce drag, but no lift because it is a symmetrical aerofoil.
b.It could stall if the fin angle of attack is too great.
Rudder controls:
Select one
a.pitch
b.yaw
c.turn
d.roll
b.yaw
The pilot uses the rudder to provide control around the:
Select one
a.lateral axis.
b.turn axis.
c.normal axis.
d.longitudinal axis.
c.normal axis.
If the right rudder pedal is pushed forward:
Select one
a.the rudder moves to the left and the aircraft yaws to the left.
b.the rudder moves to the right and the aircraft yaws to the right.
c.the rudder moves to the right and the aircraft yaws to the left.
d.the rudder moves to the left and the aircraft yaws to the right.
b.the rudder moves to the right and the aircraft yaws to the right.
