摘要： An identification system and method are provided for aircraft equipped with electric taxi systems for autonomous ground movement that enables airport ground personnel and others outside the aircraft to safely and easily identify the aircraft moving on ground surfaces at an airport as equipped with a pilot-controlled electric taxi system and to distinguish these aircraft from aircraft not moved by electric taxi systems. The identification system may be mounted with nose or main landing gear drive wheels supporting the electric taxi system. The identification system includes an identifying lighting system with lighting elements of a selected number, shape, color, or arrangement positioned on at least a visible face of one or more landing gear wheels. Automatic or manual controls may actuate the identification system to identify electric taxi system-equipped aircraft when the aircraft are moved with the electric taxi system or are stopped.

摘要： An emergency landing control system for an aircraft includes a landing site data source, a performance margin data source, an engine health data source, an aircraft health data source, and a processor. The landing site data source determines, continuously and in real-time, available landing sites. The performance margin data source conducts, continuously and in real-time, continuous performance analysis of an engine. The engine health data source determines, continuously and in real-time, available engine power as a function of time. The aircraft health data source determines, continuously and in real-time, available aircraft life as a function of time. The processor receives data from these data sources and, based on these data, continuously generates landing paths to one or more of the available landing sites, and selectively and continuously adjusts maximum available engine power up to emergency power limits, as needed, during execution of a landing maneuver to a landing site.

摘要： Methods and systems for a go/no-go Landing Decision Point (LDP) are disclosed. The methods and systems provide a graphical LDP on a cockpit display that pilots can use to determine whether to continue the landing or execute a go-around. The methods and systems may be implemented in embodiments having an onboard portion, an off-board portion, or both operatively coupled to provide an LDP in a preview/planning mode and real time mode.

摘要： A processor calculates a safe landing zone for an aircraft. The processor executes the following steps: (a) converting 4D point cloud data into Cartesian coordinates to form a height map of a region; (b) segmenting the height map to form boundaries of an object in the region; and (c) determining maximum height within the boundaries of the object. Also included are (d) determining if the maximum height is greater than a predetermined height to form a vertical obstruction (VO) in the region; and (e) determining if the VO is in the line of sight (LOS) of the aircraft to classify the landing zone as safe or unsafe. The processor further includes the step of: (f) forming a slope map over the height map.

摘要： Images are provided to a pilot in an aircraft overflying the earth by means of a helmet mounted display system. The position and attitude of the aircraft with respect to the earth and the attitude of the helmet with respect to the aircraft are monitored in order to convert a plurality of stored earth position signals into helmet coordinates. Earth points which are viewable by the pilot are displayed using symbolic images thereof such that the symbolic images coincide, from the pilot's point of view, with the actual positions of the viewable points on the earth.

摘要： A display source emits light. A first hologram receives the light from the display source and diffracts the received light. The light from the display source is applied to the first hologram at an incident angle A1 and moves from the first hologram at an outgoing angle B1. A second hologram receives the light from the first hologram and diffractively reflects the received light. The light diffractively reflected by the second hologram forms an image of the display source in viewer's field of view. The light from the first hologram is applied to the second hologram at an incident angle A2 and moves from the second hologram at an outgoing angle B2. The first and second holograms are nonparallel to remove a ghost image of the display source which would result from at least one of surface reflections at the first and second holograms. The first hologram has an angle .theta. relative to the second hologram. The angles A1, B1, A2, B2, and .theta. are in a fixed relationship to remove chromatic aberration which would result from the nonparallel arrangement of the first and second holograms.

摘要： A visor for mounting on a helmet adapted to be worn by an individual, includes a substantially transparent visor having an inner concave surface, and, with reference to an orthogonal, right-handed xyz Cartesian coordinate system of spatial reference having its origin located on the inner concave surface and its z-axis parallel to the line of sight of the individual wearing the helmet, the inner concave surface being defined by a cross-section of the visor in the x-axis of reference, which is symmetrical about both the origin and the y-z plane of reference, having one-half of the cross-section of the visor in the x-axis of reference being a first circular segment containing the origin at one end and connected to its opposite end to one end of a first paraboloid segment which is connected at its opposite end to one end of an elliptic segment whose opposite end forms a side boundary of the visor, and by a cross-section of the visor in the y-axis of reference having a second circular segment, one end of which forms an upper boundary of the visor and an opposite end connected to one end of a third circular segment having its opposite end connected to one end of a second paraboloid segment whose opposite end forms a lower boundary of the visor.

摘要： A head-up visual approach instrument having a display of flight guidance information for a two-segment approach to touchdown. The display includes flight path indicia which the pilot aligns with an outside world aiming point, as the touchdown zone of a runway. During the first segment the flight path indicia is positioned as a function of aircraft altitude to define the changing sight angle to the target.

摘要： A device for indicating the direction to a remote object comprises at least one disc-like unit consisting of a plurality of elongated light guides, arranged in parallel, mechanically interconnected but optically insulated from each other. The end surfaces of the light guides located in one end surface of the unit face the object and their opposite end surfaces are facing the observer who sees a light area, or spot, composed by light passing through those guides which are right before his eyes. When the light spot is in level with his line of sight to the object the longitudinal axes of the light guides indicate the direction to the object. In a preferred embodiment two units are used one of which is rigidly mounted in a vehicle whereas the other one is pivotable around an axis perpendicular to the longitudinal axes and to the end surfaces of the light guides. The pivoting movement is controlled by one or more variables representative of the spatial situation of the vehicle.
