Chapter 1: Basic Aerodynamics Flashcards
Ther term “angle of attack” is defined as the angle
between the wing chord line and the relative wind
The angle between the chord line of an airfoil and the relative win is known as the angle of
attack
Angle of attack is defined as the angle between the chord line of an airfoil and the
direction of the relative wind
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
The four forces acting on an airplane in flight are
lift, weight, thrust, and drag
Select the four flight fundamentals involved in maneuvering an aircraft:
straight-and-level flight, turns, climbs, and descents
Ground effect is most likely to result in which problem?
Becoming airborne before reaching recommended takeoff speed.
When landing behind a large aircraft, which procedure should be followed for vortex avoidance?
Stay at or above the large aircraft’s final approach path.
How does the wake turbulence vortex circulate around each wingtip?
Outward, upward, and around each tip
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
sink into the flightpath of aircraft operating below the aircraft generating the turbulence
Wingtip vortices are created only when an aircraft is
developing lift
The greatest vortex strength occurs when the generating aircraft is
heavy, clean, and slow
Wingtip vortices created by large aircraft tend to
sink below the aircraft generating turbulence
The wind condition that requires maximum caution when avoiding wake turbulence on landing is a
light, quartering tailwind
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying
above the large aircraft’s final approach path and landing beyond the large aircraft’s touchdown point
