What spacing rule applies when staggering during EOR?

• A. No closer than 1/2 ship length to aircraft in front
• B. Maintain at least 2 ship lengths
• C. Maintain 3 ship lengths
• D. No spacing requirement

Answer: (A)

In EOR operations, the key idea is to keep enough space between aircraft so they can maneuver safely without risking contact or wingtip interference as the lineup shifts. The spacing rule uses a practical, consistent measure: stay at least half a ship length away from the aircraft in front. That provides adequate clearance for wing movement, tail clearance, and smooth taxiing or positioning, even if the lead aircraft slows or adjusts. Choosing more generous spacing—like two or three ship lengths—would slow the operation and waste deck space, while having no spacing at all creates a real collision risk. So, the safest, most efficient rule is to maintain at least half a ship length to the aircraft ahead.
