What is the recommended approach for determining the size of a temporary landing site?

The recommended approach for determining the size of a temporary landing site is to make it twice the diameter of the rotor. This measure ensures that there is a sufficient safety margin around the helicopter when it lands or takes off, accounting for its movements and wind effects. The larger space allows for safe maneuvering and reduces the risk of collision with obstacles or personnel on the ground.

This sizing approach is particularly important in emergency situations where quick landing might be necessary. Ensuring the landing zone is appropriate in size can enhance safety for both the aircraft and any surrounding individuals.

The other options may not provide adequate space for safe landings and takeoffs. For instance, equal to rotor diameter or 100' x 100' might not account for variations in rotor sizes and maneuvering space required, while having the site dependent on wind conditions could lead to inconsistency and potentially dangerous landing scenarios. Therefore, maintaining a size that is twice the diameter of the rotor is crucial for operational safety.
