Which mechanism causes a helicopter's tail rotor to lose effectiveness during landing in strong crosswinds?

💡 Explanation

Vortex ring state ingestion reduces tail rotor thrust because the tail rotor operates within its own turbulent downwash, therefore decreasing its ability to counteract main rotor torque, rather than other aerodynamic phenomena influencing stability.
