ACN stands for?

ACN stands for?

• A. Air Current Number.
• B. Annual Congestion Number.
• C. Asphalt Cure Number.
• D. Aircraft Classification Number.

Answer: (D)

ACN stands for Aircraft Classification Number, a rating used in airfield pavement management to express the relative loading effect an aircraft’s landing gear has on pavement. It isn’t simply the aircraft’s weight; it accounts for how the load is distributed by the gear—tire size and count, number of axles, suspension, and the way loads are delivered during landing and taxi. This number lets engineers compare different aircraft’s impact on a given pavement surface without tying the assessment to a specific operational condition. Pavement strength is described separately by PCN (Pavement Classification Number). You compare the two: if the aircraft’s ACN is less than or equal to the pavement’s PCN, operation is acceptable; if ACN exceeds PCN, restrictions or pavement strengthening may be needed. The other terms aren’t used to describe how aircraft load affects pavements: they don’t represent the loading relationship used for determining compatibility.
