This method is structured so a pavement with a particular PCN value can support, without weight restrictions, an airplane that has an ACN value equal to or less than the pavement's PCN value. This is possible because ACN and PCN values are computed using the same technical basis. Applies only to pavements with bearing strengths of 12,500 pounds or greater.
