When determining the Take-Off Distance for Performance Class A aeroplanes, assuming an engine failure on a wet or contaminated runway, the screen height is...
  • A
    35 ft.
  • B
    15 ft.
  • C
    20 ft.
  • D
    50 ft.

Class A Net Take-off Distance Required

The take-off distance required is the greatest of the following three distances:

  • All engines operating. The horizontal distance travelled, with all engines operating, to reach a screen height of 35 ft multiplied by 1.15
  • One engine inoperative (dry runway). The horizontal distance from BRP to the point at which the airplane attains 35 ft, assuming the critical power unit fails at VEF on a dry, hard surface.
One engine inoperative (wet runway). The horizontal distance from BRP to the point at which the airplane attains 15 ft, assuming the critical power unit fails at VEF on a wet or contaminated hard surface, achieved in a manner consistent with the achievement of V2 by 35 ft.
