# Chapter 1: Basic Aerodynamics Flashcards

1
Q

Ther term “angle of attack” is defined as the angle

A

between the wing chord line and the relative wind

2
Q

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

A

attack

3
Q

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

A

direction of the relative wind

4
Q

Which statement relates to Bernoulli’s principle?

A

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

5
Q

The four forces acting on an airplane in flight are

A

lift, weight, thrust, and drag

6
Q

Select the four flight fundamentals involved in maneuvering an aircraft:

A

straight-and-level flight, turns, climbs, and descents

7
Q

Ground effect is most likely to result in which problem?

A

Becoming airborne before reaching recommended takeoff speed.

8
Q

When landing behind a large aircraft, which procedure should be followed for vortex avoidance?

A

Stay at or above the large aircraft’s final approach path.

9
Q

How does the wake turbulence vortex circulate around each wingtip?

A

Outward, upward, and around each tip

10
Q

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

A

sink into the flightpath of aircraft operating below the aircraft generating the turbulence

11
Q

Wingtip vortices are created only when an aircraft is

A

developing lift

12
Q

The greatest vortex strength occurs when the generating aircraft is

A

heavy, clean, and slow

13
Q

Wingtip vortices created by large aircraft tend to

A

sink below the aircraft generating turbulence

14
Q

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

A

light, quartering tailwind

15
Q

When landing behind a large aircraft, the pilot should avoid wake turbulence by staying

A

above the large aircraft’s final approach path and landing beyond the large aircraft’s touchdown point

16
Q

When departing behind a heavy aircraft, the pilot should avoid wake turbulenc by maneuvering the aircraft

A

above and upwind from the heavy aircraft
