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
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
The application of inertial navigation and guidance systems to civil air transport operations from the systems engineering viewpoint is developed. The concept of an operational system for navigation and guidance is introduced to facilitate consideration of the relationships which will exist between the inertial system and the operating functions necessary for the conduct of a flight. Inertial system configurations satisfying the requirements implied by these relationships are presented. The general requirements for input data panels and system output displays for all flight phases are discussed. Several basic navigation system mechanizations are analyzed and the general characteristics of a recommended configuration for an integrated navigation and guidance system described. The report also includes an estimate of the system performance required for the various flight phases. (Author).

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. (Author).
