The present invention is directed to a system and methods, embodiments of which provide increased situation awareness information in an improved Synthetic Vision System (SVS). According to the present invention, a Primary Flight Display (PFD), a top-down view Multi-Function Display (MFD), and side-view Vertical Profile Display (VPD) are presented on one user interface with an input device, such as a transparent touch screen for quick and easy data entry. The present invention also provides color shading, such as red, to communicate areas where the aircraft may be in conflict with terrain or obstacles at a point in time in the future.

A flight control system includes a primary flight display having a hover display which facilitates operations in DVE conditions. The hover display includes a radar altitude display, heading drift symbology and lateral drift symbology which assists pilots in the detection of drift, which is common in DVE situations and to provide the pilot with a salient cue pertinent to the approach to hover and landing.

A display system for a vehicle includes a navigation database storing navigation data; a terrain sensor configured to gather terrain data; a processor adapted to receive the navigation data and the terrain data and operable to supply one or more image rendering display commands based upon the navigation data and the terrain data; and a display device. The display device is coupled to receive the image rendering display commands and operable, in response thereto, to render (i) a perspective view image representative of the terrain data and the navigation data and including terrain and (ii) at least one line on the perspective view image that extends at least partially across the terrain and represents at least one of a ground-referenced range to a fixed location on the terrain and a vehicle-referenced range from the vehicle to a fixed range away from the vehicle.

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.

A system and method displays a synthetic vision system (SVS) image combined with a primary flight display (PFD) including a compass indicating the aircraft heading. An arc on or near the outer edge of the compass indicates the viewing frustum of the SVS view.

A standby flight display system for use on an aircraft is disclosed herein. The aircraft has a primary flight display system that is configured to display a first image on a primary flight display screen. The standby flight display system includes a subsystem configured to determine a dynamic state of the aircraft. The standby flight display system further includes an image generator. The standby flight display system still further includes a processing unit. The subsystem, the image generator, and the processing unit are each independent of the primary flight display system. The processing unit is communicatively coupled with the subsystem and with the image generator and is configured to receive information from the subsystem relating to the dynamic state of the aircraft and to control the image generator to generate a second image overlaying the first image on the primary flight display screen.

The invention provides a primary flight display instrument in which a symbol—such as a small star or triangle—indicates the bearing to the current waypoint in the flight navigation plan. The display may also show a bearing indication symbol showing a follow-on waypoint in the flight plan. These symbols are preferably located on the horizon line of the primary flight display (or the attitude indicator) providing bearing to the current waypoint in the flight plan and/or to the following waypoint. An image processing unit generates the display, including earth ground and horizon, in a view substantially conformal with a VMC view from the aircraft.

A vehicle attitude display such as a Primary Flight Display presents pitch and bank information by displaying a vehicle avatar as fixed, with respect to a moving artificial horizon whilst displaying a movable symbol at a position along the vehicle avatar that is proportional to the symmetry of the vehicle. Parts of the display are dynamically emphasised or de-emphasised to support rapid assimilation of key data. Display format may be dynamically adjusted depending on vehicle use conditions. Display is intended for use both in-vehicle, and remotely.

Improved systems and methods for dynamic readouts on a primary flight display are provided. The system includes a computer system configured to receive and process aircraft status data and flight plan data to command a display system to overlay on the image, (i) an analog indicator of the airspeed, (ii) an analog indicator of altitude, (iii) a digital airspeed indicator, and (iv) a digital altitude indicator. The system continuously determines whether steady flight conditions are occurring. Steady flight conditions include one or both of: constant airspeed and constant rate of change of airspeed. When the steady flight conditions are occurring, (i) and (ii) are removed from the image. When the steady flight conditions are no longer occurring, (i) and (ii) again overlaid on the image.
