Under what conditions are doghouse straps required?

The requirement for doghouse straps is specifically tied to maintaining stability and safety during various environmental conditions. The correct answer indicates that doghouse straps are necessary when afloat at all times and onshore when the wind speeds exceed 15 knots.

When the aircraft is afloat, the dynamic environment presented by water can lead to movement and potential shifting of the aircraft, making the use of doghouse straps essential for securing it in place. This ensures that the aircraft remains stable and secure, preventing any unintended movements that could lead to damage or injury.

Moreover, onshore conditions, specifically when wind speeds exceed 15 knots, create enough force that could also impact the stability of the helicopter. Under these circumstances, the straps provide an extra layer of security to counteract windy conditions that might otherwise compromise the safety and integrity of the aircraft.

Thus, doghouse straps are an integral part of handling practices to ensure that the aircraft is secured under specific environmental conditions, reinforcing safe operational standards both at sea and when docked in potentially windy conditions.
