This report describes an extensive evaluation of Loran-C for use by general aviation. Flight, ground, and antenna tests were done. Flight tests measured the accuracy and the ability to make approaches. Receiver reliability and susceptibility to atmospheric noise were also studied. Ground tests looked into grid stability and grid war page. Antenna tests were done to evaluate three antenna configurations -- ADF, vertical whip, and trailing wire antennas. The measured accuracy met FAA AC 90-45A requirements for all phases of flight. Loran-C was found to be satisfactory for approaches within AC 90-45A specifications. Reliability was 99.7%, the receiver was insensitive to atmospheric noise. The time difference grid was stable in the long run. Antenna tests showed the ADF and vertical whip antennas to be suitable for airborne use. It is concluded that Loran-C is suitable for navigation as an alternative to VHF RNAV. This navigation system is suitable for use in general aviation aircraft.
