Dectra (Decca Track/Range) is one of two British systems recommended at the March 1954. meeting of Com. Division of I.C.A.O. in Montreal for evaluation by interested States. Arrangements are now being made to commence proving trials of Dectra at the end of this year or possibly the beginning of 1957. The trials will be made under the auspices of the Ministry of Supply and Ministry of Transport and Civil Aviation in this country and with the support of the Department of Transport in Newfoundland. The system is primarily designed for the navigation of fast jet aircraft across the North Atlantic, a problem intensified by air traffic control when more than 100 aircraft are in the air at the same time on those routes. It is, however, likely to prove valuable for other similar applications. The trials installation will cover the main route Prestwick–Gander.
