Flight demonstration of 3D perspective synthetic vision and ADS-B for closely spaced parallel approaches

Abstract

Airports lose significant capacity during instnunent conditions. Several plans are afoot to expand the nations' airports to achieve sufficient runway spacing for independent IFR approaches. The projected cost of the ten largest projects in the United States is $8 -16 Billion. The ability to conduct Closely Spaced Parallel Approaches (CSPA) in Instrument Meteorological Conditions (IMC) could reduce the requisite runway separation and significantly lower that national expense. In addition the environmental impact of airport capacity increases would be significantly reduced. This paper presents a synthetic vision display and ~ the supporting flight system to attempt to achieve this goal. The display presents the pilot with the information necessary to aviate, navigate and monitor traflic on the parallel approach. This paper also documents the first series of flight experiments to test the applicability of synthetic vision displays to CSPA Operations (Figure 1).

Computing Danger Zones for Provably Safe Closely Spaced Parallel Approaches

“…To display the danger zones to the pilot, Jennings et al 15 developed a cockpit display, as shown in Fig. 8, in which the algorithm was implemented in C using OpenGL and Open GVS (Quantum3D) graphics libraries on an 800-MHz Intel processor with nVidia GeForce3 graphics card.…”

ADS‐B aided robust relay selection for cooperative communications in aircraft approach

“…In SVS, data link technology is adopted for the signal transmission from the control tower to the approaching aircraft. However, because of the high speed and low elevation of the approaching aircraft, the performance of point-to-point data link suffers from serious multipath fading in the flight test [3,4].…”

The ground-to-air communications in the aircraft approach stage suffer from multipath fading. However, because of the high speed and low elevation of the approaching aircraft, the performance of point-to-point data link suffers from serious multipath fading in the flight test [3,4].In the last decade, cooperative communication technique has received much attention in the communication society [5][6][7], which is proved to be effective in combating multipath fading by exploiting the spatial diversity of the relay nodes. The relay selection problem is formulated to minimize the spectrum cost while preserving the signal-to-noise-ratio (SNR) outage requirement of the approaching aircraft.

Evaluating Visualization Modes for Closely-Spaced Parallel Approaches

“…Jennings, et al (2002) used a synthetic vision system with a "3D tunnel in the sky" to demonstrate paired approaches with actual aircraft. However, this was not conducted as a controlled experiment.…”
