Letters

In the Sept. 9 “Cockpit Viewpoint” (p. 51) Capt. Robson criticized the Airlines Electronic Engineering Committee for developing an Airline ADF Equipment Characteristic based on a “decade” or “digital” tuning concept. Since the publication of this column the “Letters to the Editor” have indicated some degree of support for the views expressed by Capt. Robson, however, as Capt. Robson knows, the strong objections to his viewpoint by many airline people have been expressed to us, rather than to your office.
