Which of the following is NOT a technical selection factor for HLZ?

Operational Costs is not considered a technical selection factor for a Helicopter Landing Zone (HLZ). Technical selection factors primarily focus on the physical and environmental parameters that influence the feasibility and safety of landing and taking off from a specific location. These include elements such as landing formations, atmospheric conditions, and surface conditions, as they directly impact the helicopter's performance.

Landing formations relate to how helicopters are arranged during operations, impacting their safety and efficiency. Atmospheric conditions refer to weather factors such as wind speed, visibility, and temperature, which can affect maneuverability. Surface conditions pertain to the actual make-up of the landing area, including terrain type and obstacles, which are critical for ensuring a safe landing and take-off.

In contrast, operational costs are more related to the budgetary and logistical considerations of the mission rather than the technical aspects of the HLZ. While understanding costs is vital for planning and resource allocation, it does not play a direct role in the technical safety or feasibility of utilizing a landing zone for helicopter operations.
