Which two practices help reduce runway incursions during busy periods?

• A. Long-winded surface instructions and vague hold-short procedures
• B. Clear, concise surface instructions and the use of hold-short lines with positive read-back or confirmation
• C. Relying on pilot discretion and informal phrases
• D. Minimizing radio transmissions and moving traffic quickly.

Answer: (B)

Clear, concise surface instructions reduce ambiguity about taxi routes, hold points, and when to stop, which is crucial when airport traffic is busy. Using hold-short lines with positive read-back or confirmation gives pilots a definite point to stop and a verifiable understanding of the clearance, so any mishearing or confusion is caught before an aircraft enters or crosses a runway. Together, these practices minimize miscommunication and timing errors that can lead to runway incursions. In contrast, long-winded or vague instructions, reliance on pilot discretion and informal phrases, or rushing transmissions and movement increases the risk of misreads and missed hold points.
