Loran-C Nonprecision Approaches in the Northeast Corridor.

Abstract

This report describes a flight test designed to investigate the suitability of Loran-C as a nonprecision approach aid in the Northeast Corridor (NEC). Approaches were flown at six selected airports in the NEC by a CH-53A helicopter using Loran-C for course guidance. Accuracy criteria specified in Advisory Circular (AC) 90-45A were used as the standard for acceptability. Data were recorded for Loran in area calibrated and uncalibrated modes along with very high frequency omnidirectional radio range (VOR)/distance measuring equipment (DME) raw sensor data for comparison. The results show that the group repetition interval (GRI)-9960 Northeast U.S. Loran-C chain met AC 90-45A requirements for nonprecision approaches in all cases when a local area calibration was applied. The uncalibrated mode met AC 95-45A requirements at four of the six airports. It was determined that the Seneca, Nantucket, Carolina Beach triad should be used for navigation throughout the flight test area. (Author)
