Likewise, the… …   Aviation dictionary, aircraft load rating — Number expressing the relative structural loading effect of an aircraft on a pavement.

In the ACN of flexible pavement, the alpha factor or pavement reduction factor, is used to take into account the effect of gear geometry in computing pavement design curves for flexible pavements. consistent. Hence, if The ACN is a single unique number that expresses the relative effect of an airplane of a given weight on a pavement structure for a specified standard subgrade strength.

The rigid pavements have four subgrade categories: Aircraft: A320-200.

group developed and ICAO adopted the Aircraft Classification Number - Pavement Classification Number (ACN-PCN) method. The pavement classification number (PCN) is an International Civil Aviation Organization (ICAO) standard used in combination with the aircraft classification number (ACN) to indicate the strength of a runway, taxiway or airport ramp. A for high strength : characterized by K = 150 MN/m^3 and representing all K values above 120 MN/m^3 for rigid pavements, and by CBR = 15 and representing all CBR values above 13 for flexible pavements. The main goal of the Aircraft Classification Number and Pavement Classification Number method is protecting the runway, apron, and taxiway from excessive wear and tear. The result is then multiplied by 100 and given as percentage.

This information is published in a standardized format following the guidelines provided in the Annex 14 of ICAO Regulations.

D. Ultra Low Strength – CBR 3 (For CBR below 4%). About ATR For any given PCN value, the aircraft should meet this value, which is assigned by calculating the Aircraft Classification Number (ACN). To obtain a classification number for a multi-wheel undercarriage an ESWL has to be calculated and to do this, a pavement thickness must be defined. The PCN is a five-part code associated to any section of the airport pavements (runway, taxiways, aprons or ramps) and indicates its mechanical resistance with respect to excessive wear and tear. This paper introduces a method to obtain the PCN of airport pavement.

All Type 2 and Type 3 runways must have a LCN and the aircraft undercarriage design must comply with it.

This number is the Aircraft Classification Number … A typical ACN for a given aircraft is normally provided as follows: The actual ACN of a given aircraft of weight M and corresponding to a pavement with known characteristics can be calculated as follows: ACNmin and ACNmax are the ACN corresponding to Mmin and Mmax respectively. U indicates usage – a physical testing regime, ICAO Documentation Annex 14 - Aerodromes - Volume I - Aerodrome Design and Operation - 8th Edition July 2018 - Chapter 2.6. Four subgrade categories are defined (high, medium, low, and ultra low) for each pavement type (flexible or rigid). An exhaustive list of the ACN for most of the existing aircraft can be found in IVAO HQ documentation. All the human activity which surrounds aircraft is… …   Wikipedia, Pennant number — In the modern Royal Navy, and other navies of Europe and the Commonwealth, ships are identified by pennant numbers (sometimes referred to as pendant numbers). This study is helpful for the health and safe operation of airport pavement.

In the meantime, an interim alpha factor of 0.72 for six wheels per landing gear would be used by aircraft manufacturers, until such time the results of the test were available.

To obtain a classification number for a multi-wheel undercarriage an ESWL has to be calculated and to do this, a pavement thickness must be defined. This… …   Wikipedia, pavement classification number — A number expressing the bearing strength of a pavement for unrestricted operation (ICAO).

ACNs must be calculated using a prescribed technical method, which is clearly defined. Finally, the PCN and the strength grade of airport pavement are determined. The ACN expresses the effect of individual aircraft on different pavements by a single unique number, which varies according to pavement type and subgrade strength, without specifying a particular pavement thickness. The number is obtained by making plate bearing tests on the pavement. http://mediawiki.ivao.aero/index.php?title=ACN_-_PCN&oldid=10846, About IVAO - International Virtual Aviation Organisation.

ACN values are published for both flexible and rigid pavements and at four (4) subgrade categories that span the range of subgrade and bearing support values normally encountered. The calculated ACN is then compared to the PCN of the foreseen airport pavements to assess the feasibility of the aircraft manoeuvre and operations.
