Which statement about an alternate LZ is NOT true?

• A. The alternate LZ is the backup ready if the primary cannot be used
• B. Conditions determine when to switch to the alternate
• C. The alternate should be prepared in advance
• D. The primary and alternate are always used simultaneously

Answer: (D)

Redundancy and the ability to switch quickly define LZ planning. The alternate landing zone exists as a ready backup if the primary cannot be used due to weather, smoke, debris, obstacles, or threats. It should be prepared in advance so the crew can shift to it without delay. The decision to switch is driven by current conditions and risk assessment—if the primary becomes unsafe, you move to the alternate. Because the goal is a clear, coordinated retreat to a safer option, the primary and alternate aren’t intended to be used at the same time for the same operation. That’s why the statement about both being used simultaneously isn’t true.
