The regular maintenance pattern for runways 5 and 23 includes which of the following dimensions?

• A. Half-length of runway
• B. Full length of runway
• C. Average length of runway
• D. Shortened length due to construction

Answer: (B)

The correct choice is full length of runway, which indicates that regular maintenance for runways is conducted over their entire length. This practice ensures that the entire surface of the runway is kept in optimal condition to provide safe and reliable operations for aircraft. Regular maintenance across the full length allows for thorough inspections, repairs, and any necessary cleaning to mitigate potential hazards such as debris or surface deterioration.

Addressing the context for the other options, the half-length of runway would not be sufficient to cover all potential issues that could arise over the entire surface area that an aircraft utilizes during takeoff and landing. The average length of runway is not a specific measurement that applies consistently, as runways can vary significantly in size and capacity. Lastly, a shortened length due to construction implies that sections of the runway would be closed off, only applying to temporary scenarios rather than the routine maintenance that is standard for maintaining the safety and integrity of the entire runway.
