An auditory attitude indicator for aircraft that includes an audio source providing an audible signal, a' stereo headset with a left side and a right side, an aircraft avionics system that provides at least aircraft pitch data and roll data to an audio processor unit. The audio processor unit includes at least one lookup table of coefficients corresponding to a plurality of possible aircraft pitch and roll orientations and at least two selectable multipoint finite impulse response filters. The f...

Methods and apparatus are provided for airspace navigation. Airspace navigation information for an aircraft is displayed in a first mode, such as, in a horizontal mode. One or more navigation events may then be detected, such as, proximity to a terrain feature, weather, traffic etc. The airspace navigation information for the aircraft is then displayed using dual modes, e.g., a horizontal mode and a vertical mode. Display parameters, such as colors, resolution, distance, scale, etc. may be set a...

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...

A gyroscopic artificial horizon comprises a gyroscope suspended in a gimbal ount which has an inner frame and an outer frame pivoted, one within the other, about two orthogonal axes. It also comprises a device for sensing the spatial position of the axis of the gyroscope and for displaying this position in the form of an artificial horizon. To simplify the mechanical structure and to increase the reliability of the gyroscopic artificial horizon, the device for sensing and displaying the spatial ...

A method is disclosed for checking model planes entering into a dive, as well as an anti-dive method and apparatus. The method of checking planes includes installation of a first optical sensor in the upper part of the plane, with installation angle upwardly intersecting with the front of the plane at .alpha. degrees, that checks light intensity and outputs a first checked optical signal; installation of a second optical sensor in the bottom part of the plane, with its installation angle downwar...

A data processing system and method of operation thereof detect when a situation occurs in which a window displayed on a display device should be brought to a user's attention. That window is then surfaced at the top of a window system z-order of the data processing system without modifying a current activation state of the window. Thus, while the window is guaranteed to be visible or unobscured by any other windows, the current activation state is not changed and any user input is still in cont...

The specification discloses an arrangement for synchronizing the speeds of and controlling the phase of engines and, in particular, the engines of twin engine airplanes. In the arrangement, one engine is a master engine and the other is a slave engine, and the speeds and phase of the engines are compared and signals are provided in conformity with the results of the comparison to speed up or slow down the slave engine to bring the speed and phase thereof into conformity with that of the master e...

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...

A method for displaying flight information includes displaying a first characteristic sign illustrating a speed vector of an aircraft. The method also includes determining a first longitudinal margin of maneuver of the aircraft as a load factor, and displaying a second characteristic sign such that a position of the second characteristic sign relative to the first characteristic sign illustrates the first longitudinal margin of maneuver.

A graphical display of a vertical speed indicator showing "fly-to" and "no-fly" commands on the periphery of a vertical speed indicator during TCAS traffic or resolution advisory conditions.
