In other words, a rate of descent of the aircraft proportional to the lowering of the nose will be obtained.

  • this supplementa ⁇ ry control gives the opposite effect in that a low power setting means, a high rate of descent and a high power setting means a low rate of descent.
  • This arrangement makes it possible to raise the nose of aircraft 15 at the final part of the landing procedure, because the rate of descent will be independ ⁇ ent of the position of maneuver handle 55.
