3. AERODROME CODE
A system of code numbers and letters selected for aerodrome planning purposes in accordance with the characteristics of the airplane
Aerodrome reference code number depend on Approach speeds and also on the wind span of Aircraft.
Four categories designated as A,B,C, D, E bassed on approach speeds in Knots with a wing span of 48 to 260’
