What does the Pavement Classification Number (PCN) indicate to pilots and operators?

• A. The maximum pavement bearing strength for unrestricted aircraft operations.
• B. The average maintenance cost of the runway.
• C. The recommended taxiway lighting configuration.
• D. The total pavement thickness.

Answer: (A)

The main idea is that the Pavement Classification Number measures how much load a pavement can safely carry. It represents the maximum bearing strength of the pavement for aircraft operations, indicating the structural capacity to support aircraft loads without sustaining damage. Pilots and operators use PCN to decide if a given aircraft can operate on a runway by comparing it with the aircraft’s own load classification; if the aircraft’s classification is within the pavement’s bearing strength (ACN ≤ PCN), operations can proceed with standard conditions. If not, restrictions or pavement work may be required. The other choices don’t fit because PCN isn’t about cost, lighting configurations, or pavement thickness. It’s specifically about the structural capacity of the pavement to bear aircraft loads.
