What is the required size for a landing zone during the day?

The required size for a landing zone during the day is 100 x 100 feet. This dimension provides a sufficient area for helicopters to safely land and take off in various conditions while allowing for a safe perimeter. A landing zone of this size ensures that there is enough space for the rotor wash to dissipate and minimizes the risk of obstacles that could interfere with the aircraft's operation. Generally, this size is considered standard for helicopter operations during daylight hours to enhance safety and operational efficiency.

Larger sizes such as 150 x 150 feet or 200 x 200 feet may be recommended for nighttime operations or for larger helicopters, where increased safety margins are necessary due to reduced visibility. However, for daytime landing, 100 x 100 feet is typically adequate, enabling quick access for emergency services while maintaining safety protocols.
