Patent number: 8260492Abstract: A method and system for redundancy management is provided for a distributed and recoverable digital control system. The method uses unique redundancy management techniques to achieve recovery and restoration of redundant elements to full operation in an asynchronous environment. The system includes a first computing unit comprising a pair of redundant computational lanes for generating redundant control commands. One or more internal monitors detect data errors in the control commands, and provide a recovery trigger to the first computing unit. A second redundant computing unit provides the same features as the first computing unit. A first actuator control unit is configured to provide blending and monitoring of the control commands from the first and second computing units, and to provide a recovery trigger to each of the first and second computing units. A second actuator control unit provides the same features as the first actuator control unit.Type: GrantFiled: May 4, 2006Date of Patent: September 4, 2012Assignee: Honeywell International Inc.Inventors: Kent Stange, Richard Hess, Gerald B Kelley, Randy Rogers

Publication number: 20110040431Abstract: Methods and systems for operating an avionics system on-board an aircraft are provided. In one embodiment, an indication of a position of the aircraft is received, the position is calculated based on the indication, the calculated position is compared to navigational information to establish the suitability of the calculated position for initiating a take off roll path, and an indication of the results is generated. In another embodiment, a desired angle of attack is determined, and during the automated take off, the pitch is adjusted such that an actual angle of attack is substantially the same as the desired angle of attack. In a further embodiment, data associated with a take off roll is received, one or more v-speeds of the aircraft associated with the take off roll are calculated, and during the take off roll, the aircraft is controlled based on the one or more calculated v-speeds.Type: ApplicationFiled: August 11, 2009Publication date: February 17, 2011Applicant: Honeywell International Inc.Inventors: Scot Griffith, Kent Stange

Patent number: 7840316Abstract: An aircraft flight control surface actuation control system includes an actuator control unit and a flight control module. The actuator control unit includes at least two independent actuator control channels to generate limited authority flight control surface actuator commands based on pilot inceptor position signals and flight control augmentation data. The flight control module supplies the flight control augmentation data to each of the independent actuator control channels, determines operability of each of the actuator control channels and, based on the determined operability of each independent actuator control channel, selectively prevents one of the independent actuator control channels from supplying the limited authority flight control surface actuator commands. The flight control module may also generate full authority flight control surface actuator commands for supply to flight control surface actuators.Type: GrantFiled: December 17, 2007Date of Patent: November 23, 2010Assignee: Honeywell International Inc.Inventors: Larry J.
