COMFAA 3.0 accompanies Advisory Circular AC 150/5335-5C, “Standardized Method of Reporting Airport Pavement Strength – PCN,” and is designed to work with the COMFAA 3.0 support spreadsheet. The current version is dated August 14, 2014. COMFAA 3.0 differs from the previous version, COMFAA 2.0, in that external file manipulation is fully supported and the procedure for computing flexible and rigid pavement PCNs, as described in AC 150/5335-5C, is fully automated. The procedure for computing PCNs requires only that the user enter the aircraft traffic mix, pavement foundation strength, pavement thickness, and (for rigid pavements) the concrete strength. See the advisory circular for more information on using COMFAA 3.0.
