What is the difference between PCN and ACN?
PCN is an International Civil Aviation Organisation (ICAO) standard used in combination with the Aircraft Classification Number (ACN) to indicate the strength of a runway, taxiway or apron. The PCN is actually expressed as a five-part code, separated by forward-slashes, describing the piece of pavement concerned.
Can ACN exceed PCN?
An aircraft having an ACN (at a given weight) equal to or less than the PCN can operate without restriction on the pavement, provided that its tire pressure does not exceed the PCN limitation.
What does ACN mean in aviation?
Aircraft Classification Number
Aircraft Classification Number (ACN) is a number that expresses the relative effect of an aircraft at a given configuration on a pavement structure for a specified standard subgrade strength.
How do I find my ACN?
ACNs must be calculated using a prescribed technical method, which is clearly defined. An aircraft’s ACN is calculated from its weight, its wheel layout, its tire pressure, and to the ICAO strength category. ACN’s are calculated according to the computer listings given in the ICAO Airport Pavement Design Manual.
