  • Performance Improvement Methods for Terrain Database Integrity
    PERFORMANCE IMPROVEMENT METHODS FOR TERRAIN DATABASE INTEGRITY MONITORS AND TERRAIN REFERENCED NAVIGATION A thesis presented to the Faculty of the Fritz J. and Dolores H. Russ College of Engineering and Technology of Ohio University In partial fulfillment of the requirements for the degree Master of Science Ananth Kalyan Vadlamani March 2004 This thesis entitled PERFORMANCE IMPROVEMENT METHODS FOR TERRAIN DATABASE INTEGRITY MONITORS AND TERRAIN REFERENCED NAVIGATION BY ANANTH KALYAN VADLAMANI has been approved for the School of Electrical Engineering and Computer Science and the Russ College of Engineering and Technology by Maarten Uijt de Haag Assistant Professor of Electrical Engineering and Computer Science R. Dennis Irwin Dean, Russ College of Engineering and Technology VADLAMANI, ANANTH K. M.S. March 2004. Electrical Engineering and Computer Science Performance Improvement Methods for Terrain Database Integrity Monitors and Terrain Referenced Navigation (115pp.) Director of Thesis: Maarten Uijt de Haag Terrain database integrity monitors and terrain-referenced navigation systems are based on performing a comparison between stored terrain elevations with data from airborne sensors like radar altimeters, inertial measurement units, GPS receivers etc. This thesis introduces the concept of a spatial terrain database integrity monitor and discusses methods to improve its performance. Furthermore, this thesis discusses an improvement of the terrain-referenced aircraft position estimation for aircraft navigation using only the information from downward-looking sensors and terrain databases, and not the information from the inertial measurement unit. Vertical and horizontal failures of the terrain database are characterized. Time and frequency domain techniques such as the Kalman filter, the autocorrelation function and spectral estimation are designed to evaluate the performance of the proposed integrity monitor and position estimator performance using flight test data from Eagle/Vail, CO, Juneau, AK, Asheville, NC and Albany, OH.

Each has its own operational challenges. And for some, these challenges have grown — as busier airspace and ever-more- demanding flight environments have increased the focus on safety, industry wide. An FAA task force identified three primary areas where operational risks for helicopters need special attention: 1) inadvertent flight into instrument meteorological (IMC) conditions, 2) night operations, and 3) controlled flight into terrain (CFIT). Many ongoing studies have reinforced these findings. And in response, many operators are now asking for technologies that can proactively (and affordably) help address these safety issues. To that end, Garmin is focusing our decades of experience in aviation safety technology on the specialized needs of today’s helicopter community.

It is not the function of the Board to assign fault or determine civil or criminal liability. Aviation Occurrence Report Gear-Up Landing Cougar Helicopters Inc. Eurocopter AS332L Super Puma (Helicopter) C-GQCH St. John=s, Newfoundland 01 July 1997 Report Number A97A0136 Summary The crew of the Super Puma helicopter, serial number 2139, were conducting an instrument landing system (ILS) approach to runway 29 in St. John=s, Newfoundland. As the helicopter was about to touch down, the crew realized that the helicopter was lower than normal and that the landing gear was still retracted. The crew began to bring the helicopter into a hover; however, as collective pitch was applied, the nose of the helicopter contacted the runway surface. Once the hover was established, the landing gear was lowered and the helicopter landed without further incident. Damage was confined to two communications antennae, and the supporting fuselage structure of the aircraft. There were no injuries to the 2 crew members or 11 passengers. 2 Other Factual Information The flight crew were certified and qualified for the flight in accordance to exsisting regulations. The occurrence flight was the second flight of the day for the flight crew. For the first flight of the day, the first crew member arrived at 0700 Newfoundland daylight time (NDT) for the planned morning flight.

The method of increasing the altitude measurement accuracy has been realized in a form of a frequency deviation increase with the help of the carrier frequency increase. In this way, the height measurement precision has been established at the value of ±0.75 m. Modern digital processing of a differential frequency cannot increase the accuracy limitation considerably. It can be seen that further increase of the height measurement precision is possible through the method of innovatory processing of so-called height pulses.
