Nota Adicional1
During an approach to hover or running landing, the helicopter is flying first in undisturbed air and reaches a speed of approximately 16 to 12 knots where the helicopter enters its vortices and loses translational lift. At this point, the helicopter will increase its descent rate unless power is increased to compensate for the loss of translational lift. Tail rotor thrust must be increased to compensate for operation in disturbed air and the increase in main rotor thrust.
Contexto
HALLOW APPROACH AND RUNNING/ROLL-ON LANDING: Use a shallow approach and running landing when a high-density altitude or a high gross weight condition, or some combination thereof, is such that a normal or steep approach cannot be made because of insufficient power to hover. To compensate for this lack of power, a shallow approach and running landing makes use of translational lift until surface contact is made. If flying a wheeled helicopter, you can also use a roll-on landing to minimize the effect of downwash. The glide angle for a shallow approach is approximately 5°. Since the helicopter will be sliding or rolling to a stop during this maneuver, the landing area must be smooth and long enough to accomplish this task.
