Classification of Aerodromes

Classification of Aerodromes The aerodromes in India are classified as follows: I.(a) Central Government aerodromes (b) Privately owned licensed aerodromes II.(a) State Govt. aerodromes normally maintained in a serviceable condition (b) State Govt. aerodromes not necessarily maintained in a serviceable condition III. Air force aerodromes available for limited civil use

Classification of Aerodromes An air force aerodrome is generally not expected to be used for schedules or non-schedules air service nor even for local flights or flying displays. The classification is based on the use by the civil aircrafts and military aircrafts.

ICAO Classification The airports are classified by various agencies, the most popular one being by International Civil Aviation Organization (ICAO). The airport classification aims at achieving the uniformity in the design standards. The classification by ICAO is based in the following two ways:

ICAO Classification The code letters A to E are used, as shown in table 3-1, to indicate basic runway length, width of runway pavement and maximum longitudinal grade. The number 1 to 7 are mentioned, as shown in Table 3-2 to indicate single isolated wheel load and tyre pressure.

Table 3-1 ICAO Airport Classification Airport Type Basic Runway Length (m) Width of Runway Pavement (m) Maximum longitudinal grade (%) Maximum Minimum A Over 2100 2100 45 1.5 B 2099 1500 C 1499 900 30 D 899 750 22.5 2.0 E 749 600 18

Table 3-1 ICAO Airport Classification Code No. Single Isolated Wheel Load (Kg) Tyre Pressure (Kg/cm2) 1 45,000 8.5 2 34,000 7.0 3 27,000 4 20,000 5 13,000 6.0 6 7,000 5.0 7 2,000 2.5

ICAO Classification Thus, an airport classified as B-2 would have basic runway width between 1500 m to 2099 m and would be capable of handling single isolated wheel load of 34,000 Kg with a tyre pressure of 7 Kg/cm2.

Summary The aerodromes in India are classified 3 types An air force aerodrome is generally not expected to be used for schedules or non-schedules air service nor even for local flights or flying displays. The airports are classified by various agencies, the most popular one being by International Civil Aviation Organization (ICAO).

Summary The code letters A to E are used to indicate basic runway length, width of runway pavement and maximum longitudinal grade. The number 1 to 7 are mentioned to indicate single isolated wheel load and tyre pressure.
