Abstract: A method of designating and communicating a desired LZ to an aircraft includes outputting a coded laser signal at or near a desired landing zone to indicate a location of the desired landing zone. The coded laser signal is received by an aircraft that desires to land at the desired landing zone. The location of the desired landing zone and an ingress path from a current location of the aircraft to the desired landing zone are determined by a processor provided with the aircraft.

Abstract: Systems and methods for alerting a flight crew when the vertical situation display may be providing incomplete information due to the presence of a non-computed trajectory segment in the flight plan. A processing device in signal communication with a flight management system, a position measuring system, and a velocity measuring system receives a flight plan from the flight management system and determines if the flight plan includes any non-computed trajectory segments. If at least one of time or distance to the beginning of a next non-computed trajectory segment is less than a threshold value, the processing device generates an alert that information displayed on a vertical situation display may be incomplete. An output device outputs the generated alert.

Abstract: An infrared laser landing marker system provides a capability to mark a boundary line of varying lengths with near infrared lasers, e.g., of the order 8xx nm. This system can be either directly operated or remotely operated via satellite communications and is compatible with currently fielded night vision goggles. Two modules, placed at either end of boundary, self align to each other and then proceed to mark a boundary edge of a landing zone with an infrared laser line.

Abstract: A visual aid for the pilot of an aircraft approaching to land on an aircraft carrier comprises a series of lights (9) embedded along the landing deck and controlled in response to pitch and heave of the vessel so that the light(s) illuminated at any time indicate a visual aim point which is stabilised with respect to a specified glideslope (5) onto the vessel irrespective of such vertical excursions of the vessel. It is used in conjunction with a marker on a head up display or helmet mounted display for example so that registry of the marker with the illuminated light at any time indicates that the aircraft is on the correct glideslope.

Abstract: A precision approach path indicator system (PAPI) including multiple LHA indicators and power sources. Each LHA indicator comprises several assembly modules, with each module made up of several red and white LEDs, several collimating lens, one optical combiner, and one projection lens set. From a side view of the module, the red LEDs are placed on top of white LEDs, with a collimating lens in front of each LED. The optical combiner is in front of both the red and white LEDs, slightly above the white LEDs in vertical placement. The optical combiner has a reflective coating on the bottom surface, and a red light filter coating on the projection surface. The combined beam of light is projected out through a projection lens at front of the assembly module.

Abstract: The device (1) comprises means (5) for calculating a controlled speed enabling the aircraft to observe a longitudinal separation relative to an aircraft of the convoy that precedes it.

Abstract: A portable autonomous terminal guidance system can be located in an aircraft landing zone. The terminal guidance system generates a signal indicative of the position, the terrain, and the meteorological conditions where the guidance system is located. A receiving aircraft may process the signal produced by the terminal guidance system to generate a self-contained GPS obstacle-avoidance approach path for the aircraft to the landing zone.

Abstract: The invention relates to a system for signalling and locating vehicles involved in accidents, stopped vehicles and vehicles with mechanical problems in daytime and night-time conditions as well as in adverse weather conditions. According to the invention, the occupants of the vehicle can raise the alarm without leaving the vehicle such as to avoid any physical risk. The invention comprises a case and a hinged cover housing an air container. One end of the air container is connected to a gaseous fluid outlet pipe and to a manual quick-opening non-return valve which is located in the mouth of an empty aerostatic inflatable fluorescent body. The aforementioned body is folded inside the case when not in use and is deployed in the event of a vehicle impact by means of a device comprising an inertia sensor which is activated by a deceleration force exceeding 3G and which is powered by a power source comprising batteries or accumulators belonging to the electric circuit of the vehicle or independent batteries.

Abstract: According to an example embodiment, a method includes receiving data about an aircraft that is moving on a surface using at least a first wheel, the data descriptive of physical characteristics of the aircraft, calculating a first path of the first wheel along the surface using the data, and displaying the first path in relation to a boundary between a first area of the surface and a second area of the surface, the first area safe for the aircraft, the second area unsafe for the aircraft.

Abstract: A pilot is maneuvering an aircraft on a ground surface, such as a runway or taxiway. On a cockpit display, the pilot sees a scaled aircraft symbol overlaying a moving map on a cockpit display. The aircraft symbol represents the aircraft, while the moving map represents the ground surface on which the aircraft is located. The aircraft symbol depicts its nose gear and main gear with respect to the ground surface. The nose gear on the aircraft symbol rotates based on tiller angle. The cockpit display also shows edge guidance lines that allow the pilot to line up the main gear, while providing a margin of safety. Predictive symbology also overlays the moving map to provide an indication of whether the aircraft can safely turn on the ground surface.

Abstract: A navigation system provides a shore-based continuous visual signal to a ship navigating a channel or approaching a jetty. This indicates to the ship the optimum velocity program that it should be following, which is normally a gradual reduction of speed as the ship approaches its destination. The signal is a moire fringe display (33, 34, 35) from a rotating projector (21) which tracks the intended path under the control of a computer program. From the ship, the fringes are static if it is at the correct speed, but they move in one or other direction to indicate too fast or too slow. If the ship strays beyond an acceptable sector, the projector and program can be stepped on or back to maintain an appropriate signal visible to the ship.
