53 Federal Aviation Administration 52 Additional ppts

54 Federal Aviation Administration 53 FAA AC 150/5335-5B STANDARD METHOD FOR REPORTING AIRPORT PAVEMENT STRENGTH (PCN) The standardized method, known as the Aircraft Classification Number – Pavement Classification Number (ACN-PCN) method, has been developed and adopted as an international standard and has facilitated the exchange of pavement strength rating information. Definition of ACN. ACN is a number that expresses the relative effect of an aircraft at a given configuration on a pavement structure for a specified standard subgrade strength. Definition of PCN. PCN is a number that expresses the load-carrying capacity of a pavement for unrestricted operations. System Methodology. The ACN-PCN system is structured so a pavement with a particular PCN value can support an aircraft 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.

55 Federal Aviation Administration AC 150/5335-5A “STANDARDIZED METHOD OF REPORTING AIRPORT PAVEMENT STRENGTH – PCN” The Pavement Classification Number (PCN) field has been added to FAA Form 5010 and data collection is underway. During each airport inspection, the airport owner will be asked to provide runway PCN information. This means the Aircraft Gross Weight fields on the 5010 will no longer be used to describe load carrying capacity of runways.

56 Federal Aviation Administration AC 150/5335-5A …PCN The Master Record is required to be updated periodically. PCN is now mandatory and Gross Weight data will possibly be phased out with time. Gross Weight data may transition. PCN data request now part of all airport inspections

57 Federal Aviation Administration FAA Guidance on PCN Calculation 2005 – The PCN field was re-activated in the Form 5010 Database. September, AC 150/5335-5A “Standardized Method of Reporting Airport Pavement Strength – PCN” was released to standardize the procedures for computing and reporting PCN values for inclusion in the 5010 database. (Complete re-write of AC 150/ )

58 Federal Aviation Administration FAA Guidance on PCN Calculation AC 150/5335-5A was based in large part on the procedures described in Boeing Report D “Precise Methods for Estimating Pavement Classification Number,” D is, in turn, based in large part on recommendations contained in the ICAO Aerodrome Pavement Design Manual dated 1983.

59 Federal Aviation Administration AC 150/5335-5B, Changes from -5A The procedure for selecting the critical aircraft has been substantially revised. The procedure used in AC 150/5335-5A for computing equivalent departures has been replaced by a procedure based on cumulative damage factor (CDF). Except for obtaining the structure and aircraft properties, the procedure has been completely automated in a revised version of the computer program COMFAA, now version 3.0. A spreadsheet application has been developed to facilitate determining the evaluation thickness and organizing the PCN results.

60 Federal Aviation Administration ACN-PCN – Technical Evaluation Basic Steps to Determine Pavement Classification Number 1)Identify pavement features and properties. 2)Determine traffic mixture. 3)Convert traffic to equivalent traffic of “critical” aircraft. 4)Determine maximum allowable operating weight of critical airplane. 5)Determine ACN of critical airplane at maximum allowable operating weight. 6)Repeat with each airplane set as the critical airplane. 7)Report PCN.

61 Federal Aviation Administration 60 FAA AC 150/5335-5B STANDARD METHOD FOR REPORTING AIRPORT PAVEMENT STRENGTH (PCN)

62 Federal Aviation Administration 61 FAA 150/ B USE OF NONDESTRUCTIVE DEVICES IN THE EVALUATION OF AIRPORT PAVEMENTS This advisory circular (AC) focuses on nondestructive testing (NDT) equipment that measures pavement surface deflections after applying a static or dynamic load to the pavement. Principal Changes. Since the previous revision, the FAA has developed and implemented the pavement design program FAARFIELD. Chapter 8 - NDT-BASED EVALUATION AND DESIGN INPUTS is updated to reflect the requirements of FAARFIELD rather than the previous design program LEDFAA.
