Presently VOR transmitters must be routinely checked by special flight inspection aircraft every 120 to 150 days. This project was conducted to see if the routine checks could be replaced by recording performance data of user aircraft along an airway. With sufficient samples, a statistical analysis might then show VOR radial performance to a degree of accuracy such that Special Flight Inspections would only be required at occasional intervals on those navaids shown to be out of tolerance. Special calibrations were made of the SIE 0.059 degree radial and compared with the User performance. Detailed analysis of the latter was made with respect to the effects of aircraft operators, aircraft type, and wind. It is concluded that flight checking of navaids by User aircraft is technically, operationally, and economically feasible.
