Description/Instructions Date
FAARFIELD 1.305 (9/30/2010) FAARFIELD 1.305 became the FAA standard for airfield pavement design upon publication of AC 150/5320-6E, which required the use of the FAARFIELD program.  
COMFAA 3.0 (Updated 8/14/2014) COMFAA 3.0, as introduced in version B of AC 150/5335-5, is the recommended method to determine airport runway, taxiway, and apron pavement strength with the Aircraft Classification Number - Pavement Classification Number (ACN-PCN) method. The software is capable of calculating Aircraft Classifications Numbers in accordance with the International Civil Aviation Organization (ICAO) procedure. August 2011
