aerodrome - Aerodrome (Gr. aer, air; dromos, course)
aerodrome - Original term applied to an aviation ground at which aircraft operate and are housed. Up to the beginning of the Second Great War aerodromes usually consisted of flat pasture land of differing acreage. In the early days of flying and during the First Great War they were of the simplest form, being grass-covered areas cleared of obstructions such as trees and hedges and often undrained. Hangars and workshops were primitive structures of wood or of the Besseueau fabric-covered wood-frame type.
The development of military aircraft, particularly the heavy bomber, necessitated marked changes in aerodrome planning and construction. The great all-up weights of these aircraft and their high minimum speeds during take-offs and landings called for a hard surface on the ground and a great increase in ground space available for these operations. Two or more runways built of concrete or tarmac and laid out according to the prevailing winds were therefore incorporated in the layout of service aerodromes. These runways may be thousands of yards long and link with concrete "aprons" adjoining the aircraft hangars. Perimeter tracks, similarly surfaced, are built around the aerodromes for aircraft to taxi to the starting-points before takeoff and to be moved away from the runways after landing. Aerodromes constructed with extensive concrete aprons and runways began to be adopted to a limited extent some years before the war in a few countries where flat grass surfaces are not usually found. These aerodromes were termini for air lines. Coinciding with the development of aerodrome planning were important advances in the design of aerodrome lighting, radio " beam" systems to assist airmen to land safely in darkness and bad visibility, and methods of obtaining fog dispersal (q.v.).
In the early days of flying there were fewer than a dozen aerodromes in Britain, and after more than thirty years some of these, through their long association with flying, carry historical interest. Brook-lands aerodrome at Weybridge, Surrey, for example, was the scene of the pioneer work of such men as A. V. Roe (now Sir Alliott Verdon Roe) and T. O. M. Sopwith. The aerodrome at Hendon was opened in 1910 by Claude Grahame-White, the famous veteran airman.
During the Second Great War the word " aerodrome " tended to be replaced by the word " airfield,'' which is generally used in the United States to describe a flying ground. A terminal aerodrome is usually described as an airport. See Airfield; Airport; Hendon Aerodrome.
