An Evaluation test on the navigation accuracy of an RNAV (Area Navigation) system, using the Lock-heed L-1011, was carried out by the Electronic Navigation Research Institute in collaboration with All Nippon Airways and the Japan Civil Aviation Bureau in November 1974. This paper deals with the method and the result of this flight test on the evidence of traces obtained with the automatic photographic radar recorder set up on the CRT display of the airport surveillance radar at Tokyo International Airport.
The cross track errors of the aircraft are calculated as a measure of the navigation accuracy on the basis of the data taken by the method mentioned above and we compared them with the FAA RNAV criterion, Advisory Circular AC90-45A. The result with some assumptions shows that the cross track errors are within the tolerance mentioned above.
