What best describes the difference between a landing zone (LZ) and a pickup zone (PZ) in rotary-wing operations?

• A. An LZ is for aircraft takeoff only; a PZ is for landing and unloading.
• B. An LZ is where aircraft land and offload; a PZ is where personnel or loads are picked up or loaded during or after flight; zones can be co-located or separate.
• C. LZ and PZ are identical and interchangeable.
• D. LZ is for medical evacuation.

Answer: (B)

The main idea here is that rotary-wing operations use distinct zones for different phases of the mission. A landing zone is the area where the helicopter touches down and offloads personnel or equipment. A pickup zone is the area designated for loading or picking up personnel or loads during or after flight, and it can be used separately from the landing zone or at the same location if the situation allows. This separation helps control rotor wash, approach and departure paths, and safety when crews are loading or unloading.

The other descriptions don’t fit because the landing zone is not limited to takeoff, and the pickup zone is not simply a landing area for unloading. LZ and PZ are not identical or interchangeable. And while a landing zone can be used for medical evacuation, that’s just one possible mission, not the fundamental difference between LZ and PZ.
