The report considers several aspects of the use of inertial navigation and guidance in the U. S. Domestic Air Traffic environment. It presents flight test data taken on regular scheduled commercial cargo jet aircraft flights of the Sperry SGN-10 Inertial Navigation system INS. It further presents an operational study of inertial guidance as compared with the present VORTAC system of navigation. The results of the data analysis and the study indicate that it is feasible to use inertial navigation during the enroute portion of the flight and that benefits can thereby be obtained. It also shows that very little use of the system could be realized in the terminal areas under the present standard instrument departures SIDs and approach procedures. A cost-benefit study showed that the cost of operation and ownership exceeded the benefits derived unless the cost of operation was prorated with some other service, such as international guidance.
