Abstract: In an embodiment, a method of managing force equalization (FEQ) on a vehicle utilizing redundant actuation systems for one or more control surfaces includes determining, via a force sensor, a measured force applied by a first actuation system in relation to a control surface, where the control surface is redundantly serviced by a plurality of actuation systems. The method also includes updating a measured-force time series for the first actuation system with the measured force. The method also includes analyzing movement over at least a portion of the measured-force time series. The method also includes identifying a force-fight cycle in the measured-force time series. The method also includes indicating the force-fight cycle in cumulative force-fight cycle data for the first actuation system.

Abstract: In an embodiment, a method of monitoring force equalization (FEQ) sensors on a vehicle utilizing redundant actuation systems for one or more control surfaces includes determining, via a force sensor, a first measured force applied by a first actuation system in relation to a control surface, where the control surface is redundantly serviced by a plurality of actuation systems that include the first actuation system. The method also includes updating a measured-force time series for the first actuation system with the first measured force. The method also includes determining variation in at least a portion of the measured-force time series responsive to the updating. The method also includes identifying a first static condition in the measured-force time series in response to a determination that the variation in the measured-force time series is no greater than a minimum amount of variation.

Abstract: In an embodiment, an aircraft includes a pilot input device, a position sensor coupled to the pilot input device, a flight condition sensor and a flight control computer (FCC). The FCC includes a first microprocessor and a second microprocessor. The first microprocessor is configured to receive input data from the position sensor and the condition sensor and determine therefrom a first output. The second microprocessor is configured to receive input data from the position sensor and the condition sensor and determine therefrom a second output. The FCC is configured to compare the first output and the second output to yield resultant data. Responsive to a determination that the first output and the second output do not match, the FCC is configured to execute first remediation logic if the resultant data satisfies first error criteria and to execute second remediation logic if the resultant data satisfies second error criteria.

Abstract: The All-Time Calendar is a 2-in-1 calendar that displays all the twelve months of a calendar year on a page, one page for normal/ordinary years and the other for leap years. It is designed in such a way that the same calendar can be used for years, the past, the present, and the future. It shows all the dates on which a particular day of the week falls in a particular year. It also shows all the 52 weeks in a year, and on what dates they begin and end. Each page is made up two separate parts—a laminated calendar and a laminated lever, which contains the days of the week arranged in an algorithm. The lever is skillfully inserted into the calendar and manipulated to set the calendar for a particular year. The lever displays seven groups of days at a time. The calendar can be designed, either in a vertical or horizontal format and also in various shapes—Wall, Table/Desk-top or Pocket-size. There is an accompanying ‘Guide for 200 Years. The calendars can be set in one of three ways, with or without the ‘Guide’.
