In the run-up area, the wings SHALL NOT ______.

• A. Taxi in formation
• B. Overlap
• C. Enter without clearance
• D. Lift off

Answer: (B)

In the run-up area, it is critical for the wings not to overlap to maintain safety and operational efficiency. Overlapping can lead to confusion and potential collisions, as it reduces the effective separation between aircraft. Each aircraft needs a defined space to perform pre-takeoff checks safely and without interference from adjacent planes. By ensuring that the wings do not overlap, pilots can focus on their checks without the risk of inadvertent contact or miscommunication with nearby aircraft.

The other options, while they might have their restrictions in certain contexts, do not define a fundamental safety procedure as clearly as the requirement of maintaining distinct separation between wings in the run-up area. This separation is essential to avoid accidents during critical phases of ground operations.
