A method for providing off-path guidance during a descent comprises the steps of determining a current altitude (H) and a corresponding current horizontal distance (X) of the aircraft from a selected bottom of descent point (B/D). A simulation of a Basic Descent Path (BDP) is performed, and a plurality of corresponding altitude (H.sub.i) and horizontal distance (X.sub.i) points is stored in a BDP array. A horizontal distance (X.sub.B) is determined from the B/D point to a bottom point of the BDP...

A process for aqueous biphasic extraction of metallic oxides and the like from substances containing silica. Control of media pH enables efficient and effective partition of mixture components. The inventive method may be employed to remove excess silica from kaolin clay.

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...

A device to control an aircraft system in manual pilot mode, using notably a head-up display, is constituted by a display screen located at the position of a piece of equipment of the right-hand part of the instrument panel, the screen displaying information elements delivered by the replaced equipment and information elements to control the piloting task. Application for the controlling of a manual pilot phase by a co-pilot in an aircraft using a head-up display.

Systems and methods for generating navigation signals for a vehicle in an auto-avoidance situation. In one embodiment the method includes analyzing two or more paths with respect to information about obstructions stored in a database. The method disclosed then selects a path and generates navigation signals, if an auto avoidance situation exists.

An improved flight control system with an enhanced unified graphic mistrim indicator where the flight control computer provides signals to a single mistrim indicator wherein the signals represent the status of the control surfaces of the aircraft and the mistrim indicator displays a single movable reference marker, which is caused to be translated vertically in the event of pitch mistrim, is caused to be rotated right or left in the case of roll mistrim conditions, is caused to be translated rig...

An integrated vertical situation display (IVSD) for an aircraft, and method of displaying vertical situation information, are disclosed herein. The IVSD includes an electronic display for displaying the vertical situation of the aircraft, input interfaces for receiving vertical profile information signals, and a processing circuit for reading the information signals and generating display signals applied to the display therefrom. The display has a vertical profile view area to display the vertic...

An aircraft instrument for providing a pictorial display of a vertical plane position of an aircraft, helicopter or other space operated vehicle in flight in relation to radio navigation aids or other selected reference points on the ground or in space. The instrument utilizes a computing device to establish the location of the references with respect to the vehicle in flight and the vertical pictorial display portrays the vehicle as a moving symbol, such as a red dot of light or other indicator...

A flight information display for the flight deck of an aircraft showing a pictorial side view of the flight path or the area directly in front of the aircraft area having a selected distance of at least 0.5 nautical miles, comprising (a) a pictorial representation to scale of the profile of the highest elevations of a swath of terrain along said path or area, (b) an icon positioned on the left or right side of the display representing the aircraft, the altitude of which is to scale with the heig...

A method for temperature compensating a position indicator which includes a sensor for producing an output signal whose magnitude corresponds to the position of an element that is linearly movable between first and second positions and which is subject to changes in temperature within a given temperature range and wherein the output signal of the sensor contains a temperature variable offset component and the rate of increase of the output signal as the element moves from the first to the second...
