Which factor is listed as a HLZ requirement affecting entry and exit routes?

• A. Areas of approach
• B. Wind direction/velocity
• C. Elevation/size
• D. Obstacles

Answer: (A)

The key idea is that HLZ entry and exit routes are defined by designated areas of approach. These areas create clear, protected corridors the helicopter uses to come in and depart, kept free of hazards and aligned with safe approach angles. They set the paths for entering and leaving the HLZ, which is why this factor directly affects entry and exit routes.

Wind direction or velocity, elevation/size, and obstacles all influence how a landing is conducted, but they don’t define the specific entry/exit corridors themselves. Wind can alter the preferred approach, obstacles shape the overall feasibility, and elevation/size affects the landing area, yet the explicit requirement that governs the routes the aircraft uses to approach and depart is the areas of approach.
