Download or read book Air Force Microwave Landing System written by and published by . This book was released on 1994 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the approach and landing phase of aircraft flights, precision approach landing systems are the primary means of navigation during inclement weather or other adverse conditions that limit visibility. During the early 1980's, the Federal Aviation Administration demonstrated that the Microwave Landing System (Microwave System) could replace the Instrument Landing System. Based on congressional direction, the Federal Aviation Administration stated in a biennial Federal Radionavigation Plan that the Microwave System would be the standard precision landing aid for civilian and military aviation. In January 1983, the Air Force was designated the lead Military Department for Microwave System activities and was tasked to submit a plan, in coordination with the other Military Departments to the Office of the Secretary of Defense. On June 2, 1994, the Federal Aviation Administration decided to halt further development of the Microwave System for categories 2 and 3 precision approach landings and canceled two contracts for that development. Category 2 and 3 precision landing systems can guide an aircraft to a 100 foot and 50 foot or under decision point, respectively. The Federal Aviation Administration indicated that the Global Positioning System can already handle nonprecision approach landings and that the Global Positioning System bas great potential to provide precision approach landings. The Air Force Microwave System program is valued at about $224.5 million. The audit objective was to assess the DoD evaluation of current technologies to satisfy precision landing requirements.

This book was released on 1972 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: With SC-117, national, and USAF plans partially formulated for the design of a new Microwave Landing System (MLS) to meet common civil/military and common CTOL/VSTOL requirements, attention is now focused on technical and operational areas of landing where critical decisions must be made to narrow the competing techniques to a single national standard. The Air Force missions utilize not only conventional, fixed MLS installations, but also mobile MLS units quickly installed at remote or foreign airfields. A design of a very-low-cost MLS is outlined since the number of military aircraft to be equipped with MLS will be determined by the minimum cost (and minimum service configurations) of the national MLS system.

Download or read book Microwave Landing System Integration Study Volume I Summary Report written by Edward Andrews (Jr) and published by . This book was released on 1974 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of the Microwave Landing System (MLS) into a representative selection of United States Air Force aircraft is investigated to identify problems affecting Air Force requirements for MLS. Antenna configurations and signal processing and interface designs are developed for the C-130E, C-5A, FB-111A, and F-15. These configurations and designs provide data for the environmental, cost, and systems effectiveness analyses presented in this report. A comparative analysis of different approach capabilities is carried out, using the C-130E as an illustration. These capabilities include straight, curved, and stepped approach paths as well as approaches into forward operating bases. (Modified author abstract).

This book was released on 1994 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical note describes Microwave Landing System (MLS) and Precision Distance Equipment (DME/P) mathematical modeling performed for runway 19L, Andrews Air Force Base (ADW), Camp Springs, Maryland. This study evaluates the effects of scattering and shadowing from selected buildings, hangars, aircraft, and terrain. Results are provided as plots illustrating the predicted multipath levels, separation angles, and the resulting error plots from the worst case contributors. Scenarios were modeled to determine the effects of the multipath sources in the modeled environment. These resulting errors were analyzed and compared to error tolerance (FAA-STD-022d) to determine if the errors are acceptable. The effects of the ADW environment were analyzed and evaluated. It was determined that the proposed site will perform satisfactorily with no changes.

Available in PDF, EPUB and Kindle. Book excerpt: The study examined the effects of flying different microwave landing system approach profile designs with various types of conventional avionics. All the conventional systems used possessed similar limitations in that they were unable to present course guidance throughout the microwave landing system profiles. The loss of course guidance adversely affected pilot performance and, on occasion, made for unsafe conditions. (Author).

Book excerpt: The integration of the MLS into the avionics subsystems of selected Air Force aircraft was investigated in this study. Antenna configurations and signal processing and interface designs were developed. These designs were the basis for avionics environment, cost, and system effectiveness analysis of the retrofit of MLS into the C-130E, C-5A, FB-111A, and the F-15. The C-130E study was used for the comparative analysis of different approach capabilities and MLS configurations.
Download or read book Flight Test Demonstration of Automatic Landings Based on Microwave Landing System Guidance written by Don Eastman and published by . This book was released on 1976 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the USAF participation in the gathering of data for the United States submission to the International Civil Aviation Organization of a Non-Visual Precision Approach and Landing System for International Aviation. The report contains data on Time Referenced Scanning Beam Microwave Landing System accuracy, as recorded on the test aircraft during automatic approaches and landings. The report contains information on aircraft performance and pilot acceptance for performing automatic MLS instrument approaches and landings. The USAF modified T-39 aircraft was capable of flying fully coupled and automatic curved and segmented approaches through landing using TRSB MLS data. The purpose of the flight testing was to demonstrate an inherent TRSB MLS capability rather than to provide a great amount of MLS accuracy or performance data. (Author).

Book excerpt: " ... This study concludes that high power microwave weapons systems offer the prospect of significant offensive and defensive capabilities for all of the military services. The principal recommendations include the suggestion that the Department of Defense and the Air Force establish a High Power Microwave Systems Program Office for the purpose of developing these weapons and integrating them into the combatant commands. This systems program office should be a joint program office that involves the participation of the Army, Navy, and Marine Corps as well as other agencies. Only then will the U.S. military be able to maximize the development of microwave applications, minimize costs, and facilitate the transition of this unique technology to the military services and other government agencies. Not only should defense contractors be encouraged to develop the technical capabilities that would permit them to participate in microwave weapons programs, but this study also concludes that all U.S. military system should be hardened to protect them against the effects of microwaves."--Page v
