§ 7. Mr. Wigginasked the President of the Board of Trade why greater use is not made of the Decca twin-track procedure promulgated in Notice to Airmen No. 763 issued on 11th November, 1969.
§ Mr. Goronwy RobertsOnly a minority of aircraft are at present fitted with the necessary equipment.
§ Mr. WigginWhat steps is the Minister taking to encourage more airline operators to fit this equipment and thus enable greater use to be made of air space and create more efficient management of air traffic control?
§ Mr. RobertsI assume that the hon. Gentleman is referring to the Decca area navigation system. Decca was among the pioneers in this field. We have in the past given considerable support to its efforts by seeking the international acceptance of this system, and we continue to do so. We advocate its use at every possible opportunity.
