  • The Automatic Direction Finder is a primary radio navigational aid, providing a pilot or operator with a direct indication of the relative bearing of any radio transmitter to which the equipment is tuned, normally in the band 150 to 1,800 Kc/s

    Using a single transmitter the co-ordinates of which are known, a simple homing can be obtained and with the use of two or more transmitters it is possible to obtain a position fix

    To this end small beacon transmitters are often installed at airfields Most homing procedures terminate with the passage of the aircraft over the top of the beacon and this is indicated by a reversal of the bearing indicator needle

Problems Relating to the Installation and Operation of Radio Equipment in Helicopters

  • Decca Navigator Installations

  • G Hinchliffe
  • Published online by Cambridge University Press:
    26 October 2023, pp. 20-22

  • The Decca Company has great faith in the future of the helicopter and we firmly believe that co-operation between our Company and the helicopter industry—both the manufacturing and operating sides of the industry is of the utmost importance We welcome therefore, the opportunity to discuss in the most general, non-technical terms, the problems associated with the installation of Decca equipment on helicopters

    I shall refer to the equipment under three headings (1) The aerial, (2) The black boxes, (3) The controls and display, and shall consider the problems associated with each section separately

    Before proceeding, however, I must point out that there are a vast number of different combinations of Decca Navigator equipment ranging from a simple single chain receiver with flight log display only at a total installed weight of 40 lb to a nine chain receiver with decometers, lane identification and flight log weighing 100 lb
