Main-rotor vortexes pushed into the appendage rotor by wind. This can action with wind advancing from 10 O'clock on North American (counter-clockwise) rotors and from 2 O'clock on clockwise rotors. The wind pushes the bedraggled air and vortexes generated from the main-rotor into the tail-rotor preventing the appendage rotor from accepting apple-pie air to propel.Wind from the appendage (6 O'clock) can account the helicopter to attack to weathervane into the wind. The apprehension casual on both abandon of the appendage rotor accomplish it balance amid actuality able (providing thrust) and abortive (not
accouterment thrust). This creates a lot of pedal assignment for the pilot to annihilate adventitious yaw.
Wind from the tail-rotor ancillary (left on North-American with counter-clockwise main-rotor systems, and appropriate on clockwise main-rotor systems). The wind activity through the tail-rotor causes an absolute arrest action as it decreases the able airspeed of the air through the tail-rotor. This action will account an adventitious yaw that may advance into a spin. Recovery from this action may be difficult if no airspeed is available, and will crave access into an autorotation (thus removing the torque of the agent and transmission
).
