Analysis of Helicopter Position Determination Methods

Noise measurement flight tests were performed by the Federal Aviation Administration (FAA) and the Volpe Center at Dulles International Airport during June and July, 1983. These tests were originally conducted to address a series of objectives including the propagation and environmental impact of helicopter noise. Data collected from the following four selected helicopter noise measurement tests are the subject of the current analysis: Aerospatiale SA365N Dauphin 2, the Boeing Vertol 234/CH47D, the Bell 222 Twin Jet, and the Sikorsky S76A. The current analysis focuses on a proposed simplification of aircraft position determination. Currently available means of determining exact aircraft position are: radar tracking; video tape recordings of the aircraft; and the use of global positioning system. These methods can be costly and laborious. Three alternative methods for determining aircraft position were evaluated: three-point position determination, two-point position determination, and one-point position determination. In these three methods, the altitude at each position is determined by photographic technique, thus greatly reducing the cost and effort required to determine aircraft position.
