Q
  1. What are the wind regions
A
  • Weather cock
    • (120-240 degrees) the aircraft will attempt to weathervane into the wind, causing a gradual left and right yaw rate.
  • Vortex ring state
    • (210-330 degrees) Causing inboard vortices to develop on the tail rotor. The aircraft will have Pitch, Roll, and Yaw excursions, causing heading impossible to maintain and increasing pilot work load.
  • Disk vortex
    • (280-330) Vortices caused by the main rotor are directed over the tail rotor at airspeeds between 10 – 30 knots. Aircraft will experience an uncommented rapid right yaw.
