    remain the same regardless of gross weight.

  • 2

    The amount of excess load that can be imposed on the wing of an airplane depends upon the

    speed of the airplane.

  • 3

    Which V-speed represents best-rate-of-climb speed?

    VY

  • 4

    What force makes an airplane turn?

    The horizontal component of lift.

  • 5

    How does the wake turbulence vortex circulate around each wingtip?

    Outward, upward, and around each tip.

  • 6

    Wingtip vortices are created only when an aircraft is

    developing lift.

  • 7

    What is the best indicator to the pilot of the load factor on the airplane?

    How firmly the pilot is pressed into the seat during a maneuver.

  • 8

    What is one purpose of wing flaps?

    To enable the pilot to make steeper approaches to a landing without increasing the airspeed.

  • 9

    The greatest vortex strength occurs when the generating aircraft is

    heavy, clean, and slow.

  • 10

    What is the purpose of the rudder on an airplane?

    To control yaw.

  • 11

    One of the main functions of flaps during approach and landing is to

    increase the angle of descent without increasing the airspeed.

  • 12

    VS0 is defined as the

    stalling speed or minimum steady flight speed in the landing configuration.

  • 13

    What must a pilot be aware of as a result of ground effect?

    Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.

  • 14

    Which statement relates to Bernoulli's principle?

    Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface.

  • 15

    The wind condition that requires maximum caution when avoiding wake turbulence on landing is a

    light, quartering tailwind.

  • 16

    Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?

    Turns

  • 17

    The term "angle of attack" is defined as the angle

    between the wing chord line and the relative wind.

  • 18

    When does P-factor cause the airplane to yaw to the left?

    When at high angles of attack.

  • 19

    The term "angle of attack" is defined as the angle between the

    chord line of the wing and the relative wind.

  • 20

    The left turning tendency of an airplane caused by P-factor is the result of the

    propeller blade descending on the right, producing more thrust than the ascending blade on the left.

  • 21

    Angle of attack is defined as the angle between the chord line of an airfoil and the

    direction of the relative wind.

  • 22

    Which would provide the greatest gain in altitude in the shortest distance during climb after takeoff?

    VX

  • 23

    What is ground effect?

    The result of the interference of the surface of the Earth with the airflow patterns about an aircraft.

  • 24

    The rate of turn at any airspeed is dependent upon

    the horizontal lift component.

  • 25

    As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will

    remain the same as at low altitude.

  • 26

    How will frost on the wings of an airplane affect takeoff performance?

    Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.

  • 27

    When are the four forces that act on an airplane in equilibrium?

    During unaccelerated flight.

  • 28

    During an approach to a stall, an increased load factor will cause the aircraft to

    stall at a higher airspeed.

  • 29

    In what flight condition is torque effect the greatest in a single-engine airplane?

    Low airspeed, high power, high angle of attack.

  • 30

    Which V-speed represents maximum landing gear extended speed?

    VLE.

  • 31

    During a spin to the left, which wing(s) is/are stalled?

    Both wings are stalled.

  • 32

    Ground effect is most likely to result in which problem?

    Becoming airborne before reaching recommended takeoff speed.

  • 33

    A propeller rotating clockwise, as seen from the rear, creates a spiraling slipstream that tends to rotate the aircraft to the

    left around the vertical axis, and to the left around the longitudinal axis.

  • 34

    In what flight condition must an aircraft be placed in order to spin?

    Stalled.

  • 35

    The angle of attack for a propeller is defined as

    The angle between the propeller chord line and the relative wind.

  • 36

    Upon encountering severe turbulence, which flight condition should the pilot attempt to maintain?

    Level flight attitude.

  • 37

    Which V-speed represents maximum flap extended speed?

    VFE.

  • 38

    VNO is defined as the

    maximum structural cruising speed.

  • 39

    What type of stability does the horizontal stabilizer provide during flight?

    Longitudinal.

  • 40

    Which V-speed represents maneuvering speed?

    VA

  • 41

    An airplane said to be inherently stable will

    require less effort to control.

  • 42

    The four forces acting on an aircraft in forward flight are

    lift, weight, thrust, and drag.

  • 43

    After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time?

    VY.

  • 44

    Wingtip vortices created by large aircraft tend to

    sink below the aircraft generating turbulence.

  • 45

    Recovery from a stall requires

    decreasing angle of attack.

  • 46

    What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?

    Lift equals weight and thrust equals drag.

  • 47

    Which V-speed represents best-angle-of-climb speed?

    VX.

  • 48

    Airflow from two adjacent surfaces that merge and contain eddy currents, turbulence or restrict airflow is called

    interference drag.

  • 49

    In what flight condition are torque effects more pronounced in a single-engine airplane?

    Low airspeed, high power, high angle of attack.

  • 50

    What is one purpose of wing flaps?

    To enable the pilot to make steeper approaches to a landing without increasing the airspeed.

  • 51

    Changes in the center of pressure of a wing affect the aircraft's

    aerodynamic balance and controllability.

  • 52

    Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at

    less than the length of the wingspan above the surface.

  • 53

    What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?

    The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.

  • 54

    The angle between the chord line of an airfoil and the relative wind is known as the angle of

    attack.

  • 55

    When flying from one airport to another with calm wind, the airspeed closest to the ground speed will be

    True Airspeed (TAS).

  • 56

    An aircraft airfoil is designed to produce lift resulting from a difference in the

    higher air pressure below the airfoil's surface and lower air pressure above the airfoil's surface.

    The greatest vortex strength occurs when the generating aircraft is

    heavy, clean, and slow.

  • 10

    What is the purpose of the rudder on an airplane?

    To control yaw.

  • 11

    One of the main functions of flaps during approach and landing is to

    VS0 is defined as the

    stalling speed or minimum steady flight speed in the landing configuration.

  • 13

    What must a pilot be aware of as a result of ground effect?

    Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.

  • 14

    Which statement relates to Bernoulli's principle?

    Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface.

  • 15

    The wind condition that requires maximum caution when avoiding wake turbulence on landing is a

    light, quartering tailwind.

  • 16

    Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?

    Turns

  • 17

    The term "angle of attack" is defined as the angle

    between the wing chord line and the relative wind.

  • 18

    When does P-factor cause the airplane to yaw to the left?

    When at high angles of attack.

  • 19

    The term "angle of attack" is defined as the angle between the

    chord line of the wing and the relative wind.

  • 20

    The left turning tendency of an airplane caused by P-factor is the result of the

    propeller blade descending on the right, producing more thrust than the ascending blade on the left.

  • 21

    Angle of attack is defined as the angle between the chord line of an airfoil and the

    direction of the relative wind.

  • 22

    Which would provide the greatest gain in altitude in the shortest distance during climb after takeoff?

    VX

  • 23

    What is ground effect?

    The result of the interference of the surface of the Earth with the airflow patterns about an aircraft.

  • 24

    The rate of turn at any airspeed is dependent upon

    the horizontal lift component.

  • 25

    As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will

    remain the same as at low altitude.

  • 26

    How will frost on the wings of an airplane affect takeoff performance?

    Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.

  • 27

    When are the four forces that act on an airplane in equilibrium?

    During unaccelerated flight.

  • 28

    During an approach to a stall, an increased load factor will cause the aircraft to

    stall at a higher airspeed.

  • 29

    In what flight condition is torque effect the greatest in a single-engine airplane?

    Low airspeed, high power, high angle of attack.

  • 30

    Which V-speed represents maximum landing gear extended speed?

    VLE.

  • 31

    During a spin to the left, which wing(s) is/are stalled?

    Both wings are stalled.

  • 32

    Ground effect is most likely to result in which problem?

    Becoming airborne before reaching recommended takeoff speed.

  • 33

    A propeller rotating clockwise, as seen from the rear, creates a spiraling slipstream that tends to rotate the aircraft to the

    left around the vertical axis, and to the left around the longitudinal axis.

  • 34

    In what flight condition must an aircraft be placed in order to spin?

    Stalled.

  • 35

    The angle of attack for a propeller is defined as

    The angle between the propeller chord line and the relative wind.

  • 36

  • 50

    What is one purpose of wing flaps?

    To enable the pilot to make steeper approaches to a landing without increasing the airspeed.
