What should be done if the engines are running while chocking the aircraft?

When chocking an aircraft, ensuring safety is paramount, especially when the engines are running. The best practice is to wait until the engines are spooled down before proceeding with chocking. This is because running engines generate significant thrust and can create dangerous conditions such as a possible engine failure or unintended aircraft movement. The noise, vibration, and potential for foreign object damage also make it essential for ground crew members to operate in a safe environment.

Chocking the aircraft while the engines are still running increases the risk of accidents, as the possibility of unexpected engine thrust can lead to severe injuries or accidents. This protocol not only protects the ground crew but also ensures the safety of the aircraft and its crew.

While proceeding with caution might seem reasonable, it does not adequately mitigate the risk associated with working around active engines. Likewise, waiting for specific wind conditions or chocking only a section of the aircraft would not address the inherent dangers of running engines effectively. Therefore, allowing the engines to spool down before taking any action is the safest and most prudent approach to manage the situation.
