FAA AC 150/5335-5BSTANDARD METHOD FOR REPORTINGAIRPORT PAVEMENT STRENGTH (PCN)The standardized method, known as the Aircraft Classification Number –Pavement Classification Number (ACN-PCN) method, has been developed andadopted as an international standard and has facilitated the exchange of pavementstrength rating information.Definition of ACN. ACN is a number that expresses the relative effect of an aircraftat a given configuration on a pavement structure for a specified standard subgradestrength.Definition of PCN. PCN is a number that expresses the load-carrying capacity ofa pavement for unrestricted operations.System Methodology. The ACN-PCN system is structured so a pavement with aparticular PCN value can support an aircraft that has an ACN value equal to orless than the pavement’s PCN value. This is possible because ACN and PCNvalues are computed using the same technical basis.Federal AviationAdministration41

AC 150/5335-5A ―STANDARDIZED METHOD OFREPORTING AIRPORT PAVEMENT STRENGTH –PCN‖• The Pavement Classification Number (PCN) fieldhas been added to FAA Form 5010 and datacollection is underway.• During each airport inspection, the airport ownerwill be asked to provide runway PCN information.• This means the Aircraft Gross Weight fields onthe 5010 will no longer be used to describe loadcarrying capacity of runways.Federal AviationAdministration

AC 150/5335-5A …PCNGross Weight datamay transition.PCN data request now partof all airport inspections• The Master Record is required to be updatedperiodically. PCN is now mandatory and GrossWeight data will possibly be phased out with time.Federal AviationAdministration

FAA Guidance on PCN Calculation• 2005 – The PCN field was re-activated inthe Form 5010 Database.• September, 2006 - AC 150/5335-5A“Standardized Method of ReportingAirport Pavement Strength – PCN” wasreleased to standardize the proceduresfor computing and reporting PCN valuesfor inclusion in the 5010 database.(Complete re-write of AC 150/5335-5.)Federal AviationAdministration

FAA Guidance on PCN Calculation• AC 150/5335-5A was based in large parton the procedures described in BoeingReport D6-82203 “Precise Methods forEstimating Pavement ClassificationNumber,” 1998.• D6-82203 is, in turn, based in large parton recommendations contained in theICAO Aerodrome Pavement DesignManual dated 1983.Federal AviationAdministration

AC 150/5335-5B, Changes from -5A• The procedure for selecting the critical aircraft hasbeen substantially revised.• The procedure used in AC 150/5335-5A forcomputing equivalent departures has been replacedby a procedure based on cumulative damage factor(CDF).• Except for obtaining the structure and aircraftproperties, the procedure has been completelyautomated in a revised version of the computerprogram COMFAA, now version 3.0.• A spreadsheet application has been developed tofacilitate determining the evaluation thickness andorganizing the PCN results.Federal AviationAdministration

ACN-PCN – Technical EvaluationBasic Steps to Determine Pavement Classification Number1) Identify pavement features and properties.2) Determine traffic mixture.3) Convert traffic to equivalent traffic of “critical” aircraft.4) Determine maximum allowable operating weight ofcritical airplane.5) Determine ACN of critical airplane at maximum allowableoperating weight.6) Repeat with each airplane set as the critical airplane.7) Report PCN.Federal AviationAdministration
