    The method is scheduled to replace the ACN-PCN method as the official ICAO pavement rating system by November 28, 2024. [1] The method uses similar concepts as the ACN-PCN method, however, the ACR-PCR method is based on layered elastic analysis, uses standard subgrade categories for both flexible and rigid pavement, and eliminates the use of ...

    ICAO: Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.

    The Aircraft Classification Number (ACN) – Pavement Classification Number (PCN) method is a standardized international airport pavement rating system promulgated by the ICAO in 1981. The method has been the official ICAO pavement rating system for pavements intended for aircraft of apron (ramp) mass greater than 5700 kg from 1981 to 2020. [1]

    Flag of the ICAO. An aircraft type designator is a two-, three- or four-character alphanumeric code designating every aircraft type (and some sub-types) that may appear in flight planning. These codes are defined by both the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA).

    [5] [6] The ICAO 24-bit address can be represented in three digital formats: hexadecimal, octal, and binary. These addresses are used to provide a unique identity normally allocated to an individual aircraft or registration. As an example, following is the ICAO 24-bit address assigned to the Shuttle Carrier Aircraft with the registration N905NA ...

    Add a DME to the panel and the ICAO code becomes SDG/C while the FAA code remains /G. Then, if the ADF stops receiving the ICAO code becomes DGLOV/C while the FAA code remains /G. More letters with the ICAO format mean more information about the aircraft's radio navigation capability is available to the ATS controller than with the older FAA ...
