Aerodynamics 3 – Load Factor

  1.     The aircraft is in a glide. The pilot decides to slow down. Once again in equilibrium at the new, lower speed, the aircraft’s _______ will be _______ .
    1.  Attitude; more nose-up
    2.  Angle of Attack; smaller
    3.  Angle of Attack; larger
    4.  a) and c)
  2.    Angle of Attack could be defined as the angle between:
    1.  The wing and the oncoming air
    2.  The effective wing chord and the flow direction at the leading edge
    3.  Where the airplane is pointing and where it is going
    4.  Any of the above
  3.    A body that is described as ballistic is:
    1.  in equilibrium and weightless
    2.  in orbit and weightless
    3.  accelerating toward the center of the earth at zero G’s
    4.  accelerating toward the center of the earth at 1 G
  4.    The aircraft weighs 3000 pounds at takeoff. Its stalling speed is 100 knots. The pilot weighs 160 pounds. Holding altitude in a co-ordinated turn at 60° bank, the Load Factor is _______ , the wing is producing ________ pounds of lift, the stalling speed is _________ knots, and the pilot feels like he weighs _________ pounds.
    1.  2, 4140; 141; 414
    2.  1.4, 6000; 200; 320
    3.  2, 6000; 141, 320
    4.  1.4, 3000, 100, 226
  5.    The airplane wing can be said to be stalled only at:
    1.  A speed slower than the stalling speed.
    2.  A high nose-up attitude
    3.  An Angle of Attack greater than the critical angle
    4.  A Load Factor of zero
  6.    At the maneuvering speed, VA, an airplane encountering vertical gusts will:
    1.  Stall before structural damage occurs
    2.  Experience high G loadings
    3.  Experience strong turbulence
    4.  All of the above
