Landing Gear - Aerodrome reference code The purpose of the Aerodrome reference code is to match aerodrome facilities to the A/C. It is a two part code.  The first part relates to the A/C reference field length  The second to the A/C wing span and L/G outer wheel span. The details regarding the aerodrome reference code for L/G outer wheel span can be found in the ICAO aerodrome design manual Part 2 Chapter 1 (Taxiways). The code elements are reproduced as follows;
