Book Description
This report describes the results of a jet-flight evaluation of Inertial Navigation System (INS) performance in the commercial-airline operational environment, both domestic and overwater. A description of the program and a discussion of the results are presented in Volume I. Volume II presents the raw data associated with twelve typical data flights and computed values of INS 1 and INS 2 along-track and across-track error.

Book Description
This report describes the results of a jet-flight evaluation of Inertial Navigation System (INS) performance in the commercial-airline operational environment, both domestic and overwater. Evaluation objectives included (1) assessment of the compatibility of inertial techniques with the present Air Traffic Control (ATC) System, (2) determination of the relative accuracy of inertial navigation as compared with VOR/DME navigation, (3) assessment of inertial-system updating requirements, (4) evaluation of pilot-workload effects, and (5) investigation of several other aspects of the use of an inertial system in the commercial-airline environment.

Book Description
The report summarizes the work performed to evaluate the first autopilot coupled Inertial Navigation System installed in a commercial jet aircraft engaged in regular scheduled passenger operations. Contractual provisions are listed and reviewed. Modifications to the Bendix AN/ASN-46 Navigational Computer used in this program are recorded. Preflight test programs are described. Data taken during 185 flight legs of 43 flights is analyzed for BANC-461 Steering Computer Performance. Calculations are made of cross-track and along-track errors with respect to both the original flight plan and the actual coordinates used in setting up the flight legs. Predicted errors from an earlier report (RD-65-126 dated August 31, 1965) are compared with flight results. (Author).

Book Description
A Litton LN-12 Inertial Navigation System, with a Bendix Corporation Inertial Navigation Steering Computer, was flown in a Pan American World Airways DC-8 aircraft for 55 scheduled transatlantic crossings and 32 other short flights, domestic and foreign. Performance data were collected on inertial accuracy, steering behavior, track holding, maintenance, reliability, in-flight operation, position checks and azimuth drift. Eighty percent of the flights exhibited terminal errors of 10 miles or less in either latitude or longitude coordinates. The LN-12 inertial system operated 424 hours in the navigation mode, during 233 hours of which the aircraft was guided by autopilot controlled by inertial steering commands. Two transatlantic flights are examined in detail for doppler comparison in cross track miles to go, ground speed, and drift angle. These flights are also analyzed for comparison with aircraft compass heading, measured track, drift angle, miles to go, track heading, and waypoint misses, Reliability and maintenance factors were not significant during conduct of the program. Prior to commencement of the data flights, two demonstration flights of dual LN-12 inertial systems were performed. (Author).

Book Description
An evaluation is presented of the approach and landing performance of a Kalman filter aided inertial navigation system using flight data obtained from a series of approaches and landings of the CV-340 aircraft at an instrumented test area. A description of the flight test is given, in which data recorded included: (1) accelerometer signals from the platform of an INS; (2) three ranges from the Ames-Cubic Precision Ranging System; and (3) radar and barometric altimeter signals. The method of system evaluation employed was postflight processing of the recorded data using a Kalman filter which was designed for use on the XDS920 computer onboard the CV-340 aircraft. Results shown include comparisons between the trajectories as estimated by the Kalman filter aided system and as determined from cinetheodolite data. Data start initialization of the Kalman filter, operation at a practical data rate, postflight modeling of sensor errors and operation under the adverse condition of bad data are illustrated.

Book Description
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.
