In the course of developing flight navigation equipment (FNE) for the existing and advanced aircraft major importance in attached to flight research and testing, the main goal lying in determining the accuracy characteristics of the systems and devices making up PNE. A successful solution of such tasks depends on the choice of a reliable and effective method of evaluating accuracy characteris- tics. For the last 30 years the photogrammetric method (PG) has been considered one of the most reliable ways of evaluating system accuracy characteristics during flight testing. The paper contains a summary information about the use of the PG - method in aviation equipment flight testing. A variety of different ways are discussed with respect to the specific flight experiment conditions, their special features, advantages, drawbacks and accuracy characteris- tics. There are given results of the PG - method repeated use for evaluating the accuracy characteristics of various navigation sys- tems and sensors, based upon different physical principles. The ef- ficiency of using the PG - method in PNE flight testing is also shown.
