The Aircraft Classification Number (ACN) – Pavement Classification Number (PCN) method is a standardized international airport pavement rating system promulgated by the ICAO in 1981. The method has been the official ICAO pavement rating system for pavements intended for aircraft of apron (ramp) mass greater than 5700 kg from 1981 to 2020. [ 1 ]
The method uses similar concepts as the ACN-PCN method, however, the ACR-PCR method is based on layered elastic analysis, uses standard subgrade categories for both flexible and rigid pavement, and eliminates the use of alpha factor and layer equivalency factors. [2] The method relies on the comparison of two numbers:
The pCN algorithm is well-defined, with non-degenerate acceptance probability, even for target distributions on infinite-dimensional Hilbert spaces. As a consequence, when pCN is implemented on a real-world computer in large but finite dimension N , i.e. on an N -dimensional subspace of the original Hilbert space, the convergence properties ...

Polychlorinated naphthalene (PCN) are the products obtained upon treatment of naphthalene with chlorine. The generic chemical formula is C 10 H 8−(m+n) Cl (m+n) . Commercial PCNs are mixtures of up to 75 components and byproducts. [ 1 ]

BINDT maintains PCN (Personnel Certification in Non-Destructive Testing). PCN is a personnel certification scheme in NDT methods, welding inspection and condition monitoring, which is accredited by UKAS according to ISO 17024. [3] PCN certification schemes for the major NDT methods conform to BS EN ISO 9712 (2012). [4]
