In the case of losing tail rotor thrust while hovering, what is the recommended action?

Losing tail rotor thrust while hovering can lead to a severe yawing motion, as the helicopter will begin to spin uncontrollably in the direction of the main rotor. The recommended action in such a situation is to power off and allow the helicopter to settle. This approach minimizes the risk of further destabilizing the aircraft and allows for a controlled descent to the ground. By reducing power, you minimize the helicopter's horizontal speed and give yourself the best chance to manage the yawing motion safely without adding more complexity to the situation.

Allowing the helicopter to settle down can help to bring the aircraft back under control as it descends and is transitioning back to ground level, where it can be safely managed. For pilots, understanding this critical response is essential for ensuring safety during emergencies related to tail rotor failure, especially when hovering, which is often a low-speed, low-altitude situation with reduced margin for error.

The other options, while they might seem viable in a different context, are not recommended due to the increased risk they present. For instance, increasing collective and yawing left could worsen control of the helicopter during an already critical situation, while engaging the emergency rotor brake could lead to additional and unpredictable complications, and attempting to rotate and ascend might
