Which of the following is a standard day signal used by ground personnel during LZ landings?

• A. Proceed
• B. Stop
• C. Wave
• D. Yell

Answer: (B)

Ground personnel guide helicopters into a landing zone using standardized visual signals to communicate clearly with the pilot. The day signal that tells the helicopter to halt and hold position is the Stop signal. It provides an unambiguous instruction to pause movement and wait for further clearance, which is crucial for maintaining a safe approach path and preventing rotor-wash hazards or collisions with obstacles or personnel on the ground.

Procee d would imply continuing without the necessary clearance, which isn’t safe in a landing zone. A wave is too general and not a formal, universally understood command, and yelling can be drowned out by rotor noise and isn’t a reliable signal.
