Abstract: On October 9, 1981, a Supplemental Type Certificate for airborne, en route, IFR use of Loran-C was awarded to the State of Vermont following completion of a flight test program by the Transportation Systems Center, Research and Special Programs Administration of the U.S. Department of Transportation. The certification of a Beechcraft E50 aircraft equipped with a Loran-C navigator, is the fist ever granted for use of Loran-C in the National Airspace System and culminates a four-year federal-state evaluation program. This paper describes the systematic approach leading to the award. It includes a thorough examination of the certification process, the accuracy requirements described in the Federal Aviation Administration’s Advisory Circular 90-45A “Approval of Area Navigation Systems for Use in the U.S. National Aerospace System,” the organization of the program, the preparation of a flight test plan, the collection of the data base, the analysis of the data, and resulting conclusions.
