An aircraft attitude display format which maintains the horizon reference line always in view and which presents the pilot with multiple indications of aircraft attitude differing from level flight. The multiple indications include attitude registration along an angular scale and shape change of the horizon reference line. The display format has the appearance of a fish-eye lens derived optical image and is preferably placed in this form by electronic image processing--which is exemplified by an...

An address generator responsible to input parameters for generating addresses to read out the content of a memory along parallel lines disposed at an angle to the orthogonal rows and columns of storage elements. The address generator has a first pair of registers coupled by an adder to generate line corrected X addresses, a second pair of registers coupled by an adder for generating first address corrections, an adder summing said line corrected X addresses with said first address corrections to...

An artificial horizon display generator determines either sky shading or ground shading in real time as each pixel of a raster display is generated. Transition line parameters are specified by host processor, whereupon the display generator computes whether the raster line currently being generated will intersect the horizon boundary line, and if so, at what X-Y transition point. Pixels generated prior to the transition point are of the initial shading; pixels generated subsequent to the transit...

Systems and methods are provided for determining a final heading of a turning vehicle, such as a rotorcraft. The system may include an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated. The system may also include a device, such as a display, for conveying predicted final heading information to an aircraft controller, such as a pilot.

A primary flight display with three-dimensional capability provides information in an intuitive format for enhanced situational awareness. The display also includes other navigational data such as airspeed, attitude, altitude, and heading. The display may also include three view slices, a pictorial autopilot status indicator, vertical and lateral deviation and deviation history, glide slope and localizer information, airport and runway information, past position history of the aircraft and other...

A process and system are disclosed for representing flight guiding information for an aircraft. A spatial representation of the air space with at least one horizon and the previously calculated flight path of the aircraft is represented by means of video equipment. The representation of the previously calculated flight path includes the previously calculated position and previously calculated attitude of the aircraft at different moments in time. The previously calculated flight path is represen...

An improved system and method are disclosed for facilitating target aiming and aircraft control by flight crews using electronic displays. For example, an aircraft display system is disclosed that includes a database for storing target location and boundary data, a processing unit, a position and direction determination unit for use in determining the position of an aiming symbol on a display, a graphics display generator, and a visual display. The processing unit determines whether or not a sel...

The invention relates to a method device for displaying, in a way that is easy for an operator, such as a pilot in an aircraft, to grasp and understand, the direction to objects (A, B) in the surrounding space. In accordance with the invention the object is projected onto a projection surface (3) comprised of the envelope surface of a conical solid of revolution, where the operator is somewhere vertically (h) on the axis of rotation (2) about which the envelope surface (3) is created. Thereafter...

In a method and an apparatus for displaying flight management information for an aircraft, a three-dimensional display of the flight space with at least one horizon and the predicted flight path of the aircraft is effected by means of an image reproduction device. The predicted flight path is preferably displayed as a series of symbols which assume, within the flight space displayed, the predicted position and the predicted altitude of the aircraft with respect to the flight space at different p...

A head-up display system includes means generating a pitch ladder pattern having pitch bars which are straight lines with a central gap, the pitch bars representing climb angles being solid lines and the pitch bars representing dive angles being dashed lines, the pattern having a scale factor which is unity in a central region and which increases smoothly from the central region towards the extremes of the pattern, characterised in that: a) the central bar representing level flight is considerab...
