Patent number: 7788034Abstract: One popular military aircraft mission is to meet or rendezvous with another aircraft. Presently used systems have limitations in rendezvous distance, low accuracy of computed rendezvous intercept position, and wrong results in special rendezvous scenarios such in polar regions or on a collision path. The present invention makes use of a numerical algorithm to accurately compute the rendezvous interception position with a preselected tolerance/resolution. The algorithm makes no assumption of angles and uses a proven Sodanos equation to compute a distance between two points on the earth or to compute a second position away from a first position at a known distance and bearing. Using the invention, the rendezvous intercept position can be computed with greater accuracy and a further distance in any region of the globe than the prior art methods and can be used even if the aircraft are in a rendezvous or collision/chasing path.Type: GrantFiled: June 22, 2005Date of Patent: August 31, 2010Assignee: Honeywell International Inc.Inventor: Tien D.

Publication number: 20100198432Abstract: An improved stable approach monitor (SAM) system provides an audible advisory to a pilot when an aircraft is on a final landing approach. More specifically, the SAM system compares a measured airspeed of the aircraft to a predetermined flap placard speed. If the measured airspeed exceeds the predetermined flap placard speed then the improved SAM system provides an audible advisory indicating the airspeed of the aircraft is too fast. Advantageously, this audible advisory should prevent the pilot from attempting to deploy the flaps at an excessive airspeed and in turn focuses the pilot's attention on the problem at hand, which would be to reduce the airspeed of the aircraft. Once the airspeed is equal to or below the predetermined flap placard speed, the improved SAM system may provide another audible advisory informing the pilot to commence deployment of the flaps.Type: ApplicationFiled: February 4, 2009Publication date: August 5, 2010Applicant: Honeywell International Inc.Inventors: Yasuo Ishihara, Kevin J.

Patent number: 7739004Abstract: A method for automatically monitoring and alerting a fuel leak downstream of an engine fuel flow meter in an aircraft is provided. The method uses existing engine sensor data to input into a predetermined parameter model to predict the nominal fuel flow, and also compares fuel flow between a left engine and a right engine.Type: GrantFiled: November 29, 2006Date of Patent: June 15, 2010Assignee: The Boeing CompanyInventor: Richard A. Johnson

Patent number: 7729816Abstract: A system includes an angular rate sensor disposed in a vehicle for providing angular rates of the vehicle, and an instrument disposed in the vehicle for providing line-of-sight control with respect to a line-of-sight reference. The instrument includes an integrator which is configured to integrate the angular rates of the vehicle to form non-compensated attitudes. Also included is a compensator coupled across the integrator, in a feed-forward loop, for receiving the angular rates of the vehicle and outputting compensated angular rates of the vehicle. A summer combines the non-compensated attitudes and the compensated angular rates of the to vehicle to form estimated vehicle attitudes for controlling the instrument with respect to the line-of-sight reference. The compensator is configured to provide error compensation to the instrument free-of any feedback loop that uses an error signal. The compensator may include a transfer function providing a fixed gain to the received angular rates of the vehicle.Type: GrantFiled: January 23, 2006Date of Patent: June 1, 2010Assignee: ITT Manufacturing Enterprises, Inc.Inventor: Robert H. Josselson

Publication number: 20100125381Abstract: According to the invention, a terrain avoidance maneuver is engaged when the alerts of a given pair of alerts are emitted simultaneously, the triggering of one of the alerts depending on the information provided by a first measurement chain and the triggering of the other alert of the pair relying on information provided by a second measurement chain, distinct from and independent of the first chain.Type: ApplicationFiled: November 12, 2009Publication date: May 20, 2010Applicant: AIRBUS OPERATIONS (SAS)Inventors: Paule Botargues, Nicolas Caule, Christelle Ledauphin, Jerome Bailly, Isabelle Lacaze, Sylvain Thezelais, Jerome Goyet

Patent number: 7714744Abstract: An airspace awareness and warning system (“AAWS”) provides input to an airspace alert (“AA”) processor from at least one real-time aircraft system or sensor, a navigation system, and an airspace database containing three-dimensional delineations of defined airspace; the processor determines an airspace clearance surface and an aircraft airspace alert surface, and if one surface penetrates the other, the processor generates an alert signal and provides an alert signal to a crew alerting system. The two surfaces are determined by the processor by executing an algorithm(s) embedded in software containing the disclosed embodiments and methods. At least one criterion used to define an aircraft airspace alert surface is programmed to include real-time and/or static input factor data provided by at least one system or sensor input from an aircraft. Such input factor could be used to define an airspace clearance surface.Type: GrantFiled: February 8, 2008Date of Patent: May 11, 2010Assignee: Rockwell Collins, Inc.Inventor: Joel M. Wichgers

Publication number: 20100100261Abstract: According to the invention, an altitude profile (PA) representative of the terrain overflown by the aircraft (AC) is established, and then an altitude limit curve (C) which comprises an intersection with said profile (PA) upon the engagement of a terrain avoidance maneuver is determined. As soon as there is no longer any intersection of the limit curve (C) with the altitude profile (PA), said terrain avoidance maneuver is interrupted.Type: ApplicationFiled: October 20, 2009Publication date: April 22, 2010Applicant: AIRBUS OPERATIONSInventors: Paule Botargues, Nicolas Caule, Christelle Ledauphin, Jerome Bailly, Isabelle Lacaze, Sylvain Thezelais, Jerome Goyet

Patent number: 7698058Abstract: A spatial data search method, system and apparatus for identifying particular data of significance around a reference vector through the spatial data. The method involves determining a reference vector within a spatial region for which spatial data exists, loading a portion of the spatial data including the data around the reference vector into a memory buffer, and searching the spatial data in a prioritized order. The method, system and apparatus have particular utility in searching geographic data for a terrain awareness and warning system (“TAWS”) and display in an aircraft. Embodiments of the present invention provide advantages over existing sequential and radial search methods, significantly reducing the processing and calculations required and providing faster alerts to pilots.Type: GrantFiled: December 27, 2007Date of Patent: April 13, 2010Assignee: Garmin International, Inc.Inventors: Susan S.
