What is the primary objective of runway incursion prevention in the control tower?

• A. Prevent unauthorized or inadvertent entry onto an active runway and maintain safe separation between traffic.
• B. Minimize noise by delaying departures.
• C. Route all traffic through the same taxiway.
• D. Prioritize arrivals over departures at all times.

Answer: (A)

Runway incursion prevention focuses on keeping an active runway clear of unauthorized or inadvertent entry and ensuring safe separation between all traffic operating near or on the runway. In the control tower, the goal is to issue and verify clearances, monitor positions, and coordinate movements so no aircraft or vehicle enters a runway without proper authorization, reducing the risk of collisions during takeoffs and landings. This emphasis on preventing incursions and maintaining separation directly supports safety in runway operations. Other choices miss this safety priority: delaying departures for noise reduction isn’t about safety on the runway; routing all traffic through a single taxiway is impractical and unsafe; and always prioritizing arrivals over departures ignores safe sequencing and overall risk management.
