Evaluation of a Perspective-View Cockpit Display for General Aviation Using GPS

Abstract

A display that effectively utilizes 3-D differential GPS (DGPS) positioning was tested in piloted simulation and on a general aviation aircraft. This glass-cockpit instrument provides a natural, "out the window" view of the world, making the horizon, runway, and desired flight path visible to the pilot in instrument flight conditions. The flight path is depicted as a series of symbols through which the pilot flies the airplane. Altitude, heading, and airspeed are presented, along with lateral and vertical glidepath deviations. The budget, power, and form-factor constraints of light aircraft were addressed.Simulator tests and flight trials on a Piper Dakota aircraft were used to evaluate flight technical error on straight-in approaches flown with the tunnel display and with a typical Instrument Landing System (ILS) needle display. Additionally, the tunnel display provided lateral and vertical guidance on curved missed-approach procedures, for which ILS cannot provide positive course guidance.

Airdrop Guidance Display Format for Precision Airdrop Application on an Auxiliary Display Equipped Aircraft

“…Tunnel-in-the-sky is a design concept implemented in a variety of forms. Because flight takes place in three dimensions, this display format provides a perspective presentation of the outside world (Barrows, Enge, Parkinson, & Powell, 1995;Mulder, Mulder, & Stassen, 1999;Mulder & Van Der Vaart, 2006). It shows a path or tunnel through which the pilot flies the ownship symbol.…”

A proposal of handling qualities shaping for general aviation aircraft

“…For this purpose, efforts are undertaken to design aircraft exhibiting required handling qualities, and automate many navigating and piloting activities (Acree, 1994; Anon, 2000). Specialized systems of handling and navigation data visualization, which facilitate interpretation of instrument readings (for example, tunnel display), have been designed (Anon, 2000; Barrows et al , 1996; Steward, 1994). Integrated navigation systems, based on satellite systems are used; global aircraft Automatic Depended Surveillance (ADS) systems are designed (Barrows et al , 1996; Blomenhofer, 1996).…”

As far as piloting technique is concerned, limits are set by aircraft characteristics, which result from aerodynamics laws, and flight mechanics and dynamics.…”

Collision Detection System Based on Differential Carrier-Phase Global Positioning System Broadcasts

“…Collision detection algorithms using GPS have been studied, but they are based only on GPS code information [3,4]. The GPS code estimates of position can be used for level-flight airplanes, but carrier-phase (CP)-based navigation systems are essential to meet the category III accuracy requirements in a precision approach for autolanding guidance in the terminal area [1].…”
