Patent number: 6438469Abstract: A flight control system and method for controlling a circle-to-land (“CTL”) maneuver utilizes an airborne area navigator. The area navigator receives inputs on aircraft category, aircraft position and speed, airport navigation data and pilot supplied data. In response to this data, the area navigator calculates the necessary conditions for executing the CTL maneuver and outputs control commands to a flight director. The pilot then executes the CTL maneuver either manually using the information provided by the area navigator or by using the aircraft autopilot under the direction of the flight director.Type: GrantFiled: February 7, 2000Date of Patent: August 20, 2002Assignee: Honeywell International Inc.Inventors: David Brandt Dwyer, Dave Charles Maahs

Patent number: 6405107Abstract: A self contained electronic system for manual or automatic control and navigation of fixed winged aircraft using electronic position sensing such as GPS, DGPS, WAAS, and the like, as the primary sensor and making use of known flight characteristics of the aircraft to determine aircraft attitude without any interaction with the aircraft, its controls, or the outside environment and without any moving mechanical devices other than switches, dials and connectors. The automatic and visual interface between the system and the pilot provides for simplified flight controls, and a new solution to the hazard of disorientation, and will reduce the time needed for a pilot to become proficient in VFR and instrument flying. A single instrument replaces many of the conventional instruments used for flight. Navigation data is provided in an easy to understand graphical format. The pilot is told explicitly where to move aircraft controls.Type: GrantFiled: January 11, 2001Date of Patent: June 11, 2002Inventor: Gary Derman

Patent number: 6119055Abstract: An imaging apparatus for aiding landing of aircraft in weather conditions obscuring a pilot's view of a runway. The apparatus comprises a plurality of LED assemblies which are disposed along the runway. Each LED assembly includes a plurality of LEDs, a receiver and a plurality of drivers responsive to the receiver for energizing the LEDs. The LEDs of each LED assembly are pulsed on by signals from a transmitter disposed adjacent an end of the runway. The transmitter also sends synchronization signals to a receiver located on board the approaching aircraft. The receiver on the aircraft is coupled to a processor which uses the synchronization signals to determine when the LEDs are energized and when they are not energized. The processor controls a CCD camera mounted on the aircraft so as to obtain an unobstructed view of the approaching runway. The processor controls the CCD camera such that the camera takes images (i.e., frames) while the LEDs are pulsed on and also while the LEDs are off.Type: GrantFiled: December 22, 1998Date of Patent: September 12, 2000Assignee: McDonnell Douglas CorporationInventor: Isaac Richman

Patent number: 5321615Abstract: Guide elements along paths and turns of a network emit guide signals for guiding vehicles along the paths and through the turns. Control elements, located at points in the network at which the locomotion of approaching vehicles may need to be controlled, emit control signals, such as "stop" and "start" signals. The signals are preferably various modulated and unmodulated sine waves having frequencies programmable by a system supervisor that sends itineraries to vehicles prescribing their respective travel routes, each itinerary containing at least a set of identifiers uniquely corresponding to the signals emitted along the paths and turns in a travel route. The order of the set indicates the order of paths and turns to be taken while travelling a route. A system interface, hosted by each vehicle, acquires itineraries pertaining to its host vehicle and provides path/turn information to a vehicle driver--a person or an apparatus.Type: GrantFiled: December 10, 1992Date of Patent: June 14, 1994Inventors: Marvin E.

Patent number: 4667196Abstract: An active, electro-optical display system for use on fixed-wing, land-based airport runways, is disclosed for remotely guiding a pilot during visual approach and landing of an aircraft. Conventional Microwave Landing System (MLS) ground-transmitted data is air-derived on board the aircraft and data-linked to a ground receiver to produce a continuous digital data signal indicative of aircraft slant range, elevation and azimuth relative to the desired landing position. The resulting data signal is electrically coupled to a signal processor governed in accordance with control guidance laws to produce three discrete signals indicative of the magnitude and direction of the descent rate error, the flight path acceleration, and the lateral drift rate of the aircraft relative to the intended landing area.Type: GrantFiled: June 13, 1984Date of Patent: May 19, 1987Inventor: Charles E.
