Hovering Autorotation (Hover Auto) Common Mistakes | What You Need To Know

Oct 19, 2023

Autorotation is a crucial skill that every helicopter pilot must master. It's a maneuver that allows a pilot to safely land a helicopter in the event of an engine failure. Among the various autorotation techniques, hovering autorotation, often referred to as "hover auto," is particularly challenging. In this blog and video, we'll delve into some common mistakes pilots make during hovering autorotation and what you need to know to execute it safely.

1. Premature Collective Pull: One of the most common errors during hovering autorotation is pulling the collective too early. In a hover auto, you'll need to maintain a controlled descent while the rotor system keeps spinning. If you pull the collective too soon, the main rotor's RPM could drop too quickly, leading to a hard landing. Timing is critical; the collective should only be raised when you're close to the ground, allowing you to cushion the landing and minimize the risk of damage or injury.

2. Over-Controlling Cyclic: Another mistake pilots often make is over-controlling the cyclic during hovering autorotation. The cyclic controls the helicopter's pitch and roll, and excessive inputs can disrupt the delicate balance required for a smooth autorotation. Maintaining a steady attitude and avoiding abrupt movements is key. Trust the aerodynamics of the autorotation process and make gentle cyclic inputs as needed to maintain control.

3. Neglecting Proper Training: Hovering autorotation is an advanced maneuver that should only be attempted by experienced pilots who have received proper training. Neglecting this crucial aspect of training can lead to serious errors during autorotation attempts. Comprehensive training and regular practice are essential to build the muscle memory and confidence necessary to execute a hover auto safely.

In conclusion, hovering autorotation is a complex and demanding maneuver, but with proper training and attention to detail, pilots can perform it safely and effectively. Avoiding common mistakes like premature collective pulls, over-controlling cyclic inputs, and neglecting training can make all the difference in maintaining control during an engine failure scenario. As always, safety should be the top priority in helicopter operations, and mastering autorotation techniques is a critical step in ensuring the safety of both the pilot and passengers.
