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.

A landing aid method and device for an aircraft including a unit for calculating automatically in a repetitive manner, during a final approach of the aircraft with a view to landing on a landing runway, using at least a ground speed of the aircraft, a height of the aircraft in relation to the ground, and a target vertical speed representing a vertical speed required on contact with the landing runway, a slope angle of a flight path allowing the aircraft to perform a flare, checking at least the target vertical speed on contact with the landing runway, and a unit for displaying automatically, on at least one screen of the flight deck of the aircraft, a first symbol illustrating the current slope angle of the aircraft and a second symbol illustrating the calculated slope angle.
摘要:
A method for aiding the landing of an aircraft on a landing runway comprising the following steps implemented in an automatic manner by a processing unit: a) acquiring information relating to the landing runway; b) acquiring information relating to a current situation of the aircraft; f) determining a maximum roll angle, in absolute value, necessary to allow a flight of the aircraft along a trajectory between a current position and a target landing position on the landing runway; g) comparing this maximum roll angle with a predetermined limit; and h) as a function of the result of the comparison carried out in step g), commanding, if appropriate, the signaling of an alert by means of a signaling system of the aircraft.
摘要:
A rotorcraft and an automatic landing system and method thereof are provided in the present disclosure. The automatic landing system of the rotorcraft includes a controller, a laser emitter, a camera, an electronic governor and a motor configured to drive a propeller of the rotorcraft to rotate. The laser emitter and the camera are both locate in a bottom portion of an airframe of the rotorcraft. The laser emitter has two emission heads, laser beams emitted from the two emission heads respectively are symmetrical about a central axis, the central axis is perpendicular to a horizontal plane of a ground, and an angle between each laser beam and the central axis is an acute angle. Simply with an operation of the laser emitter, the camera and the controller, the flight speed and displacement of the rotorcraft can be controlled to realize automatic landing in the present disclosure.

One aspect of the present invention includes artificial vision system. The system includes an image system comprising a video source that is configured to capture sequential frames of image data of non-visible light and at least one processor configured as an image processing system. The image processing system includes a wavelet enhancement component configured to normalize each pixel of each of the sequential frames of image data and to decompose the normalized image data into a plurality of wavelet frequency bands. The image processing system also includes a video processor configured to convert the plurality of wavelet frequency bands in the sequential frames into respective visible color images. The system also includes a video display system configured to display the visible color images.
摘要:
The aircraft landing clearance indication system is constructed of a faceplate that is adapted to be secured against a surface in a cockpit. The faceplate includes a front surface that includes instructions as to operation of the system. A push button is mounted on the front surface of the faceplate. Depression of the push button illuminates the push button providing an instantaneous feedback as to the authorization of the respective airplane to land on a runway. Once the airplane has landed, the push button is depressed a second time in order to reset itself for future use. The aircraft landing clearance indication system is used during the landing checklist.
摘要:
A system and method is provided for anticipating a missed approach point (MAP) during an instrument landing of an aircraft. Symbology is generated and displayed that graphically represents a lateral distance between a runway threshold and a virtual inner marker. The MAP is identified as the location of the aircraft when the symbology reaches a displayed runway threshold.
摘要:
A method can include determining that an aircraft is on approach to a runway. The method can include determining a flight path vector (FPV) location of the aircraft based at least in part on a projected landing location with respect to the runway and determining a current airspeed of the aircraft. The method can also include performing at least one of the following: issuing a landing short alert to a pilot of the aircraft if the FPV location is at or before the runway threshold, issuing an airspeed caution alert if the FPV location is between the runway threshold and the target runway location and if the current airspeed is below a landing short envelope, and determining not to issue an alert if the FPV location is between the runway threshold and the target runway location and if the current airspeed is at or above the landing short envelope.
