Abstract:
Improved flight display systems and methods that selectively deemphasize terrain are provided. The method includes receiving and processing navigation reference point data, terrain data, and aircraft status data. Next, the method (a) renders on a display system, in real-time, a viewing segment defined as at least a navigation reference point for the aircraft, the viewing segment having terrain rendered in a first level of terrain contrast; and (b) determines that the aircraft is in a terrain deemphasis scenario when an altitude is certain low altitude operations. When the aircraft is in the terrain deemphasis scenario, the method deemphasizes terrain within a determined boundary in the viewing segment. Deemphasizing includes decreasing terrain contrast to a second level of terrain contrast within the boundary. Terrain contrast within the boundary is restored to the first level responsive to receiving a restore trigger.
Abstract:
Methods are provided for adjusting any correlation between a perspective of an onboard visual display and a current orientation of an inflight aircraft. The method comprises determining the current orientation of the inflight aircraft and determining the perspective of the visual display. The visual display is shown to a pilot of the inflight aircraft on a display element located onboard the inflight aircraft. The current orientation of the aircraft is compared with the perspective of the visual display to determine if the perspective of the visual display needs to transition to reflect the current orientation of the aircraft. If the display does need to be changed, a rate of transition of the visual display's perspective is selected based on current aircraft performance parameters. The perspective of the visual display is then transitioned to reflect the current orientation of the aircraft at the selected rate.
Abstract:
Technologically improved vision systems and methods that provide enhanced water encoding are provided. The vision system receives terrain data from a terrain database and aircraft state data from a navigation system. The vision system commands a display system to display a map image that is reflective of a view from a current location of the platform. The vision system processes terrain data and aircraft state data to identify a water feature, determine a distance between the platform and the water feature, and determine a textural representation for the water feature. The textural representation comprises a symbol and an associated symbol pattern. The vision system commands a display system to overlay, on the map image, the water feature with the textural representation.
Abstract:
Methods are provided for adjusting any correlation between a visual display perspective and a default display view of an aircraft. The method comprises determining the default display view for an inflight aircraft and determining the orientation of the visual display for the crew of the aircraft. The default display view is compared with the orientation of the visual display to determine if the visual display's perspective needs to be transitioned to reflect the default display view. If the display does need to be changed, the rate of transition of the visual display's perspective is selected based on current aircraft performance parameters.
Abstract:
Cockpit display systems and methods are provided for performing Glide Slope (G/S) validation processes during Instrument Landing System (ILS) approaches. In one embodiment, the cockpit display system utilizes validated G/S signals to selectively correct the viewpoint of a Synthetic Vision System (SVS) scene generated on a Synthetic Vision Primary Flight Display (SV-FPD). In such an embodiment, the cockpit display system may include an ILS receiver, a cockpit display device on which the SV-PFD is generated, and a controller operably coupled to the cockpit display device and to the ILS receiver. During an ILS approach, the controller selectively performs a G/S validation algorithm to determine the validity of the G/S signals received during the ILS approach. If determining that the G/S signals are valid, the controller then repeatedly updates the SVS viewpoint during the ILS approach based, at least in part, on the validated G/S signals.
Abstract:
A method for providing alerts or indications to an aircrew of an aircraft that is in-flight and approaching a destination airport includes receiving an aircrew runway selection from the aircrew of the aircraft, automatically generating a probable runway selection by the aircraft, and determining a position of the in-flight aircraft with reference to a threshold point. If the aircraft is prior to the threshold point, the method includes generating alerts and indications to the aircrew based solely on the received runway selection into the FMS from the aircrew of the aircraft and not on the automatically-generated probable runway selection from the aircraft. Alternatively, if the aircraft is past the threshold point, the method includes generating alerts and indications to the aircrew based solely on the automatically-generated probable runway selection from the aircraft and not on the received runway selection into the FMS from the aircrew of the aircraft.
Abstract:
Flight deck display systems and methods for generating cockpit displays including dynamically-adjustable runway length symbology are provided. In one embodiment, the flight deck display system includes a display device to which a controller is operably coupled. A cockpit display, such as a primary fight display, is generated on the display device. The cockpit display is generated to include a runway graphic and a usable runway end marker. During operation of the display system, the controller receives runway usage restriction data identifying any currently restricted sections of a runway approached for usage by the aircraft. The controller further determines a dynamically-adjusted usable runway length as a function of the runway usage restriction data and then adjusts the position of the usable runway end marker, as generated on the cockpit display, along the length of the runway graphic in accordance with the dynamically-adjusted usable runway length.
Abstract:
A display system for an aircraft includes a processing unit configured to determine runway lighting information for runway lighting associated with a selected runway and to generate display commands based on the runway lighting information. The runway lighting is located at a first location relative to the selected runway. The display system further includes a display device coupled the processing unit for receiving the display commands and operable to selectively render first symbology representing the runway lighting information at a second location relative to the selected runway.
Abstract:
A system and method are disclosed for indicating to an aircrew of an aircraft a normalized runway icon to ensure visualization of a predicted touchdown point, runway length, stopping distance, energy state marking, and threat conditions, where normalization is referenced to typically available length for landing. Indications of present aircraft locations relative to the icons as well as alerts when thresholds are exceeded are provided.

Systems and methods for enhanced display of obstacles in a combined vision display are provided. The system comprises a display unit and an enhanced vision system configured to generate first signals representative of enhanced vision images. Data storage device contains obstacle data representative of obstacles. Synthetic vision system is configured to selectively retrieve obstacle data from data storage device and generate second signals representative of synthetic vision images of one or more obstacles. Processor is in operable communication with display unit and coupled to receive first and second signals and configured, in response thereto, to: overlay the synthetic vision images of the one or more obstacles over the enhanced vision images and command display unit to display the synthetic vision images of the one or more obstacles overlaid over the enhanced vision images. The overlaid synthetic vision images of the one or more obstacles may be visually highlighted.
