A Loran-C cycle matching receiver (Decca Model ADL-81) was evaluated in line service to determine its qualification as a potential replacement for Loran-A. The receiver and associated components were installed on an Eastern Air Lines L1011 aircraft and data were collected by a qualified navigator on the routes between the U.S. Mainland and Puerto Rico. Results of the program indicate that cycle matchine Loran-C is a satisfactory substitute for Loran-A where usable signals are available. The equipment under evaluation provided excellent accuracy and required less flight crew attention than is normally demanded by the present Loran-A systems.
