Which factor is NOT listed as a consideration when selecting a Helicopter Landing Zone?

• A. Time of Day
• B. Location
• C. Obstacle clearance
• D. Capacity

Answer: (A)

The main idea here is choosing an HLZ based on its physical feasibility and how it fits the mission, not on when you plan to land. Time of day doesn’t change the inherent features of the landing zone, such as whether the area is near the objective (location), whether there are obstacles in the approach and departure paths (obstacle clearance), or whether the zone can handle the aircraft and number of operations planned (capacity). Those three factors determine safety and practicality of using the zone. Location matters because you want the HLZ close enough to the objective to minimize risk and time on the ground. Obstacle clearance is essential to ensure there are no trees, wires, buildings, or terrain that could intersect the approach or takeoff paths. Capacity ensures the zone is large enough for the aircraft type and the expected number of landings and takeoffs without congestion or unsafe proximity to obstacles. Time of day becomes relevant mainly for operational needs like lighting or visibility requirements during night or poor-light conditions, which influence how you operate after the site is chosen, but it isn’t a fundamental criterion used to select the HLZ itself.
