What should vehicles do when a helicopter is approaching?

When a helicopter is approaching, it is essential for vehicles to remain clear of its flight path. This is crucial for safety reasons, as helicopters have a significant rotor wash and can create turbulence, which can be hazardous to nearby vehicles and personnel. Staying clear also ensures that the helicopter has an unimpeded landing or takeoff, which is vital for the smooth operation of airside activities.

Remaining clear minimizes the risk of accidents and injuries that could occur if a vehicle were to be in the way of a flying helicopter. This action reflects the standard protocols in aviation environments where proximity to aircraft, especially helicopters, must be carefully managed to maintain a safe working atmosphere.

While other actions such as accelerating to exit the area may seem proactive, they can lead to confusion or sudden movements that might compromise safety. Similarly, parking in a safe location without ensuring it is outside the helicopter's flight path might not be sufficient. Lastly, taking off immediately is not a viable option as vehicles cannot take off like aircraft; they need to follow the designated vehicle protocols and ensure they are clear. Thus, remaining clear is the safest and most appropriate response when a helicopter is approaching.
