What do you know about the principles of flight? As far as this quiz is concerned, you must know about the use of flaps during level turns, the rectangular wing’s job or task compared to other wing platforms, what the wing directly controls, and what affects the speed of an airplane. This quiz will demonstrate your knowledge of the principles of flight. Good luck with the quiz.
The lowering of flaps increases the stall speed
The raising of flaps increases the stall speed
Raising flaps will require added forward pressure on the yoke or stick
Wingtip, with the stall progression toward the wing root
Wing root, with the stall progression toward the wingtip
Center trailing edge, with the stall progression outward toward the wing root and tip
Angle of incidence of the wing
Amount of airflow above and below the wing
Distribution of pressures acting on the wing
Lift, airspeed, and drag
Lift, airspeed and CG
Lift and airspeed, but not drag
Weight, dynamic pressure, bank angle, or pitch attitude
Dynamic pressure, but varies with weight, bank angle, and pitch attitude
Weight and pitch attitude, but varies with dynamic pressure and bank angle
Weight, load factor, and power
Load factor, angle of attack, and power
Angle of attack, weight, and air density
Angle of attack regardless of the attitude with relation to the horizon
Airspeed regardless of the attitude with relation to the horizon
Angle of attack and attitude with relation to the horizon
Changes in air density
Variations in flight altitude
Variations in airplane loading
A decrease in angle of attack will increase pressure below the wing and decrease drag
An increase in angle of attack will increase drag
An increase in angle of attack will decrease pressure below the wing and increase drag
Upward forces is less than the sum of all downward forces
Rearward forces is greater than the sum of all forward forces
Forward forces is equal to the sum of all rearward forces
Is momentarily decreased
Remains the same
Is momentarily increased
At lower airspeeds the angle of attack must be less to generate sufficient lift to maintain altitude
There is a corresponding indicated airspeed required for every angle of attack to generate sufficient lift to maintain altitude
An airfoil will always stall at the same indicated airspeed; therefore, an increase in weight will require an increase in speed to generate sufficient lift to maintain altitude
Twice as great
Half as great
Four times greater
Decreases because of lower parasite drag
Increases because of increased induced drag
Increases because of increased parasite drag
Gain in altitude over a given distance
Range and maximum distance glide
Coefficient of lift and maximum coefficient of drag
The same as at the lower airspeed
Two times greater than at the lower speed
Four times greater than at the lower speed
Negative air pressure below and a vacuum above the wing’s surface
Vacuum below the wing’s surface and greater air pressure above the wing’s surface
Higher air pressure below the wing’s surface and lower air pressure above the wing’s surface
Force acting perpendicular to the relative wind
Differential pressure acting perpendicular to the chord of the wing
Reduced pressure resulting from a laminar flow over the upper camber of an airfoil, which acts perpendicular to the mean camber
Chord line
Flightpath
Longitudinal axis
These forces are equal
Thrust is greater than drag and weight and lift are equal
Thrust is greater than drag and lift is greater than weight
Experience a reduction in ground friction and requires a slight power reduction
Experience an increase in induced drag and required more thrust
Requires a lower angle of attack to maintain the same lift coefficient
A lower angle of attack
The same angle of attack
A greater angle of attack
Increase, and induced drag will decrease
Decrease, and parasite drag will increase
Increase, and induced drag will increase
Rudder
Elevator
Ailerons
And angle of bank must be decreased
Must be increased or angle of bank decreased
Must be decreased or angle of bank increased
