Chapter 3 Jeppesen Private Pilot Test
Guide
The four forces acting on an airplane in flight are - answer lift weight thrust and drag
When are the four forces that act upon an airplane in equilibrium - answer during
uncelebrated flight
(refer to figure 1) the acute angle A is the angle of - answer attack
the term "angle of attack" is defined as the angle between the - answer chord line of the
wing and the relative wind
The angle between the chord line of an airfoil and the relative wind is known as the
angle of - answer attack
what is the relationship of lift drag thrust and weight when the airplane is in straight and
level flight - answerlift equals weight and thrust equals drag
One of the main functions of flaps during approach and landing is to - answerincrease
the angle of descent without increasing the airspeed
what is one purpose of wing flaps? - answerto enable the pilot to make steeper
approaches to a landing without increasing the airspeed
the angle of attack at which an airplane wing stalls - answerremains the same
regardless of gross weight
what is ground effect? - answerthe 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 is most realized during an
approach to land when at - answerless than the length of the wingspan above the
surface
what must a pilot be aware of as a result of ground effect? - answerInduced drag
decreases; therefore, any excess speed at the point of flare may cause considerable
floating
Ground effect is most likely to result in which problem? - answerBecoming airborne
before reaching recommended takeoff speed
