Principles Of Flight Quiz: Trivia!

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
