Fundamentals of Flight

Question 1

The four forces of flight acting on an airplane are…

Answer 1

Lift, weight, thrust, and drag

Question 2

Bernoulli’s principle in flight

Answer 2

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

Question 3

if an emergency situation requires a downwind landing, pilots should expect a faster…

Answer 3

ground speed at touchdown, a longer ground roll, and the likelihood of overshooting the desired touchdown point

Question 3

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

Answer 3

during unaccelerated flight

Question 3

The term ‘angle of attack’ is defined as

Answer 3

Between the wing cord line and the relative wind

Question 3

An airplane said to be inherently stable will

Answer 3

require less effort to control

Question 4

What determines the longitudinal stability of an airplane

Answer 4

the location of the CG(center of gravity) with respect to the center of lift

Question 5

What is the purpose of the rudder on an airplane

Answer 5

to control yaw

Question 6

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

Answer 6

remain the same regardless of altitude

Question 7

An airplane has been loaded in such a matter that CG (Center of Gravity) is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be…

A) A longer takeoff run
B) Difficulty in recovering from a stalled condition
C) Remain the same regardless of gross weight

Answer 7

B

Question 8

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

Answer 8

Stalled

Question 9

The angle of attack at which an airplane wing stalls will…

A) Increase if the CG(Center of Gravity) is moved forward
B) Change with an increase in gross weight
C) remain the same regardless of gross weight

Answer 9

C)

Question 10

What is ground effect?

Answer 10

The result of interference of the surface of the earth with the airflow patterns about the airplane

Question 11

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

A) Wingtip vortices increase creating wake turbulence problems for arriving and departing aircraft
B) Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating
C) A full stall landing will require less up elevator deflection than would a full stall when done free of ground effect

Answer 11

B

Question 12

Wingtip vortices are created only when aircraft is

Answer 12

Developing lift

Question 13

The greatest vortex strength occurs when the generating aircraft is

Answer 13

heavy, clean, and slow

Question 14

When taking off or landing at an airport where heavy aircraft are operating, one should be particularly alert to the hazards of wingtip vortices because this turbulence tends to

Answer 14

Sink into the flight path of aircraft operating below the aircraft generating turbulence

Question 15

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

A) Light, quartering headwind
B) Light, quartering tailwind
C) Strong headwind

Answer 15

B

Question 16

How does wake turbulence vortex circulate around each wingtip?

Answer 16

Outward, upward, and around each tip

Question 17

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

A) Lift equals weight, and thrust equals drag
B) Lift equals drag, and weight equals thrust
C) Lift and weight equals thrust and drag

Answer 17

A

Question 18

What is one purpose of wing flaps?

A) To enable the pilot to make steeper approaches to a landing without increasing the airspeed
B) To relieve the pilot of maintaining continuous pressure on the controls
C) To decrease the wing area to vary the lift

Answer 18

A

Question 19

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

A) Less than the length of the wingspan above the surface
B) twice the length of the wingspan above the surface
C) A higher-than-normal angle of attack

Answer 19

A

Question 20

When departing behind heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft…

Answer 20

Above and upwind from the heavy aircraft
