What does PCN stand for?

• A. Pavement Classification Number.
• B. Pavement Condition Number.
• C. Pavement Calibration Number.
• D. Pavement Coefficient Number.

Answer: (A)

PCN stands for Pavement Classification Number, a standard value used to express an airfield pavement’s bearing strength. This number (often shown with additional letters that describe the pavement type and subgrade) is the fixed capacity a runway or taxiway pavement can support under typical loads. In practice, operators compare an aircraft’s Aircraft Classification Number (ACN) to the pavement’s PCN: if the ACN is less than or equal to the PCN, the aircraft is generally permitted to operate on that surface without restrictions; if the ACN exceeds the PCN, restrictions, weight limits, or pavement strengthening may be required. The PCN is a structural, not a condition-based, assessment and is part of international aviation standards to help ensure safe and consistent pavement usage. Other terms like Pavement Condition Number, Pavement Calibration Number, or Pavement Coefficient Number aren’t standard concepts for describing pavement strength in this context. They don’t convey the bearing capacity used for evaluating aircraft compatibility with airfield surfaces.
