Book excerpt: A flight test program was flown within the coverage area of the West Coast Loran-C chain during June and July 1979. The purpose of the test was to add to the growing statistical data base that will be used to assess Loran-C as a supplement to, or replacement for, the present VOR/DME navigation system. The test objectives were to: (1) Evaluate the West Coast Loran-C chain by quantifying navigation and position errors within its coverage area; (2) Test Loran-C as a non-precision approach aid in mountainous conditions, using a commercially available Loran-C receiver/navigator, in this case a Teledyne TDL-711; (3) Record the effects of bias shifts and station outages on overall accuracy and approach procedures, especially near a baseline extension; (4) Calculate the absolute flight technical error (FTE) during Loran-C approaches using a typical general aviation aircraft. The main conclusions of the test were: The West Coast Loran-C chain appears stable and dependable. Time difference errors were consistent and related to signal propagation differences over land and over water; TDL-711 was found to be easy to operate, giving stable and repeatable course guidance, although susceptible to random loss of track, a problem which may be software related. The system did not accurately calculate cross track deviation and distance to waypoint. Without needed hardware, software, and/or procedural changes, Loran-C may not meet the RNAV non-precision approach requirements of AC 90-45A.
Download or read book Flight Test Investigation of Area Calibrated Loran C for En Route Navigation in the Gulf of Mexico written by John G. Morrow and published by . This book was released on 1982 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight tests of two Loran-C airborne navigators were conducted in the Gulf of Mexico oil/gas exploration and production area. Two systems were installed in a Federal Aviation Administration (FAA) CV-580 aircraft to examine simultaneously the performance of a Loran-C receiver operated in an area-calibrated mode and one operated in an uncalibrated model. Two separate test routes were flown over a period of 2 days. These routes covered the central and western test areas of the Gulf of Mexico and an overland route from Palacios, Texas, to Lafayette, Louisiana. An Inertial Navigation System (INS) was used as a position reference standard. The INS data were updated to correct for drift. Accuracy of the position reference from the corrected INS data was + or - 0.3 nautical mile. The flight tests indicated that the use of area calibration greatly increased the area of compliance with Advisory Circular 90-45A en route accuracy requirements in the flight test. This report is a followup of report No. FAA-RD-80-47 (FAA-CT-80-18), 'Flight Test Investigation of Loran-C for En Route Navigation in the Gulf of Mexico.'

Book excerpt: This report contains the description and results of a Loran-C flight test program conducted in the State of Alaska. The testing period was from August 1982 to September 1982. The purpose of the flight test was to identify applicable Loran-C accuracy data for the Alaskan air taxi and light aircraft operators so that a Supplemental Type Certificate (STC) can be issued in the Alaska Region for the Loran-C system tested (Teledyne TDL-711). Navigation system errors were quantified for the Loran-C unit tested. The errors were computed from knowledge of position calculated from ground truth data and the indicated position of the navigator. Signal coverage, bias and flight technical error data were also obtained. Multilateration ground truth, photographic ground truth, and data acquisition systems were carried aboard the test aircraft. The tests were concentrated in the southwest part of the Alaskan mainland. An interconnecting network of routes west of Anchorage and south of a line from Fairbanks to Kotzebue were flown for data collection.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a comprehensive flight test evaluation of a production airborne Loran-C navigator. The test were performed on a FAA approved helicopter route in the Northeast Corridor, at NAFEC in Atlantic City, New Jersey and in the Gulf of Mexico. The test aircraft used were United States Coast Guard HH52 and HH53 helicopters. The test period was from June 1978 to January 1979. The test plan and test objectives were developed jointly by the United States Coast Guard and the Federal Aviation Administration and Systems Control, Inc. (Vt), Champlain Technology Industries Division. The flight test profiles and procedures were developed for the following reasons: (1) to assess the ACceptability of Loran-C navigation in the operational ATC environment of the Northeast Corridor; (2) to determine the system use accuracy for Loran-C for enroute, terminal and non-precision approach flight; (3) to evaluate the Loran-C navigator performance in several offshore missions. The primary conclusions of this flight test evaluation were: the navigator was acceptable in the operational environment of the Northeast Corridor for both enroute and point-in-space approaches; the navigator satisfied AC 90-45A crosstrack accuracy requirements for enroute, terminal area and non-precision approaches; the production navigator satisfied alongtrack AC 90-45A accuracy requirements for enroute and terminal area, but not for non-precision approaches; the navigator performed acceptably during all phases of offshore testing.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an operational test and evaluation of a Loran-C navigation system. The tests were performed in a Coast Guard HH-52A helicopter from 21 September to 19 October 1976. The flight test profiles, procedures and test objectives were developed to determine the applicability of the prototype Loran-C navigator to Coast Guard operations as well as to assess the functional and accuracy performance of the Loran-C navigator operating as an area navigation system in the National Airspace System. The operational testing reported in this document includes search and rescue missions as well as surveillance and enforcement missions. The former consisted of evaluating the Loran-C navigator during creeping line, sector, and expanding square search patterns. The latter involved performing low altitude hovers over fixed and movable objects and documenting Loran-C accuracy and repeatability. This latter data is also directly applicable to the operations of the off-shore oil industry.

Book excerpt: This report contains the description and results of a Loran-C flight test program conducted in the continental United States (CONUS). The data collection period was during July 1983. The purpose of the program was to collect Loran-C signal coverage and accuracy data representative of low altitude, low speed operations typical of helicopters and general aviation aircraft. The test aircraft use a Beechcraft Queen Air, Model 65. The aircraft was configured with a data collection palate and multipin electrical connectors located in the aircraft cabin. A Teledyne TDL-711 navigation receiver was used in the test, utilizing an E-field antenna mounted on the top of the fuselage. A microprocessor controlled data collection system, utilizing a scanning DME and other aircraft navigation instruments, was used to record data and establish aircraft reference position. Route segments, totaling over 9500 nm covering much of CONUS, were flown during the project. Data were recorded on all route segments. Over 12,000 data points were used in the accuracy analysis. Calibration procedures, used at five locations, reduced errors throughout an area within a 75 nm radius of the calibration point. (Author).

Book excerpt: This report lists a data base for bench simulation testing aviation Loran C receivers for en route and terminal position accuracy. A set of data points was selected from Loran C stability flight tests conducted over the continental U.S. in 1984-1985 at 400 locations, 100 points in each of four Loran C chains. It may someday be used as a substitute for some of the flight testing required in an Advisory Circular or Technical Standard Order to obtain a Supplemental Type Certificate for Loran C equipment for en route and terminal aircraft operations. The report also discusses the procedures used to collect and select the data base. Keywords: Test equipment, Test methods, Radio navigation. (kr).
Download or read book Alaska Loran C Probe Test Results written by Robert Erikson and published by . This book was released on 1987 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a flight test probe into Alaska to determine the extent of usable signals in space from Loran C stations Port Clarence, Narrow Cape, and Tok, Alaska. Flight measurements indicated adequate signal strength exists from the three Loran C stations over the routes flown. Therefore, it is feasible to dual rate Port Clarence as a new secondary in the Gulf of Alaska Loran C chain. Dual rating Port Clarence will increase the area where Loran C navigation is possible by providing proper chain structure. This largely increased area will be located in the middle to southern interior of Alaska. The tests were conducted in the summer of 1985 and in the winter of 1985/86.
