Embodiment Construction

[0029] see figure 2 , the present invention may include a display device 100 of a terrain sensing (TAWS) system shown in the figure. Display device 100 employs a screen display 102, which may be an LCD rear-projection screen of the type disclosed in U.S. Patent 6,259,378 (owned by the assignee of the present invention), which is incorporated herein by reference in its entirety . The display device 100 further includes a plurality of buttons and interfaces surrounding the perimeter.

[0030] An exemplary layout of the display device will now be described. However, it is obvious that the specific button and functional arrangement described below is only an example, and the present invention is not limited thereto.

[0031] When the trigger button 104 is pressed, the screen display can be toggled between a terrain display and a relative altitude display. When the Predicted Altitude Display ("PRED") button 106 is pressed, the screen display 102 becomes a PRED display, as will ...

Abstract

Embodiments provide a method and apparatus for indicating aircraft height relative to an obstruction in a terrain awareness warning system. The method includes receiving data indicative of geographic features of an obstruction, lateral distance of the geographic features from an aircraft, height and flight path of the aircraft, calculating a projected height of the aircraft at the location of the obstruction using the data, generating a result signal, and displaying a colored indication on a display screen based on the result signal. The apparatus includes inputs for signals from instruments measuring height, flight path, and location of an aircraft, as well as an input for an instrument providing information about geographic features of terrain surrounding the aircraft.

Description

[0001] This application is a continuation-in-part of U.S. Provisional Patent Application Serial No. 60 / 239,319, filed October 10, 2000, and entitled "Terrain Sensing and Warning System (TAWS)," which is incorporated herein by reference in its entirety way to combine. technical field [0002] The present invention relates to avionics, and more particularly to altitude displays and terrain detection and warning systems. Background technique [0003] Traditional altitude displays used in Terrain Awareness Warning Systems (TAWS) on existing aircraft provide the pilot with a visual display of terrain that is above the aircraft and within a certain distance (typically 2000' below the aircraft) of the aircraft. terrain. [0004] Referring to Figure 1 of the prior art, the importance of conventional height displays is shown. In case 1, the aircraft 12 is flying along a directional course 16 at an altitude X. In case II, the aircraft 12' is flying at altitude X' along a directiona...
