Abstract:
An aircraft hover system for enabling an aircraft to hover at a target spatial location represented by GPS location coordinates. The hover system includes a display screen rendering a display including live video feed of the terrain below the airborne aircraft, a first mark overlaying the video feed, the first mark representing the current position of the aircraft relative to the terrain, and a perimeter surrounding the first mark, the portion of the terrain within the perimeter being substantially magnified compared to that of the terrain outside of the perimeter. The hover system is configured such that, as the aircraft approaches the target spatial location, the distance between the first mark and a second mark on the display gradually decreases until and finally the first and second marks coincide; the second mark representing the target spatial location.

Abstract:
Systems and methods are disclosed for a path guidance panel. The path guidance panel provides separate display screens for showing the lateral and vertical guidance information. Each screen shows the current state of the respective guidance system, and shows what, if anything, the respective guidance system will do next. This provides a convenient display for the pilot to see the current and future states of the guidance systems of the aircraft.
Abstract:
An aircraft terrain awareness warning system is disclosed that includes an interface for entering flight plan details of an aircraft including at least one waypoint. The terrain awareness warning system is configured such that potential-terrain-collision alerts are suppressed in the aircraft during landing operations performed at waypoints associated with landing zones.
Abstract:
A flight management system for controlling navigation of an aircraft includes a path guidance panel having at least one mode selector for allowing user selection of guidance mode in which the aircraft is to operate. The system also includes at least one display device having rendered thereon a navigational map. A computer module receives aircraft data from one or more aircraft components, at least one of the aircraft components being a guidance system. The computer module is configured to use information obtained from the guidance system to cause the display device to render on the navigational map a current flight plan path that is the aircraft is following.
Abstract:
A method and apparatus is provided for determining the altitude of an aircraft. In accordance with the method, Global Positioning Satellite (GPS) data is received from a plurality of GPS satellites and a GPS altitude value is determined from the GPS data. In addition, a pressure altitude value is determined. An altitude difference is determined between the GPS altitude value and the pressure altitude value. At least one of the GPS altitude value and the pressure altitude value is adjusted using the altitude difference.

Abstract:
Embodiments provide a method and apparatus for indicating aircraft (12) 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 feature from an aircraft, height and flight path of the aircraft, calculating (208) a projected height of the aircraft at the location of the obstruction using the data, generating a result signal (222), and displaying (224) 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. The apparatus includes employing the signals to calculate an effective height of the aircraft relative to the terrain, and a screen display for graphically displaying the results of the calculation.
Abstract:
Systems and methods according to present principles provide a test architecture which is designed to support software and hardware testing in an automated environment. Systems and methods are described which include a functional definition and architecture of the test system including the host environment, host-user interface, test scripts, host-to-target communications, target test module, target test shell, target commands and other supporting aspects.
