Chapter 1: "Basic Aerodynamics"
Questions and Answers
what is ground effect? the result of the interference of the surface of the Earth with the
airflow patterns about an airplane
floating caused by the phenomenon of ground effect will be most realized during an approach
to land when at less than the length of the wingspan above the surface
what must a pilot be aware of as a result of ground effect? induced drag decreases;
therefore, any excess speed at the point of flare may cause considerable floating
which is a result of the phenomenon of ground effect? the angle of attack generating lift
is increased
the airspeed range to avoid while flying in ground effect is 40 MPH and above
an aircraft leaving ground effect during takeoff will experience an increase in induced
drag and a decrease in engine performance
when landing behind a large aircraft, which procedure should be followed for vortex avoidance?
stay above its final approach flightpath all the way to touchdown
, 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 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
