  • Patent number: 10408942
    Abstract: A method of indicating whether a GPS signal received by a vehicle is accurate includes obtaining the GPS signal and calculating position information of the vehicle based on the GPS signal. The method further includes obtaining position information of another vehicle via a broadcast. The method further includes calculating a first distance information to the other vehicle based on the position information of the other vehicle and the position information of the vehicle. The method further includes obtaining a second distance information to the other vehicle via a collision avoidance system on the vehicle. The method further includes comparing the first distance information to the second distance information, and generating an indicator that the vehicle and the other vehicle may have received an inaccurate GPS signal when a result of the comparison is higher than a threshold.

  • Publication number: 20190127078
    Abstract: A method for improving inflight fuel efficiency of an aircraft includes sensing aircraft fuel weight in the aircraft fuel tanks and reading the fuel weight by a flight management system during aircraft flight; calculating a current center of gravity position from the fuel weight; calculating an aircraft longitudinal trim drag factor from the current center of gravity; and adjusting a fuel burn prediction utilizing the longitudinal trim drag factor. A system for improving aircraft inflight fuel efficiency includes a flight management system programmed to calculate a current center of gravity position from a current aircraft fuel weight, calculate a longitudinal trim drag factor from the current center of gravity, adjust a fuel burn prediction, and display in the flight deck an adjusted fuel burn prediction for each leg of aircraft flight, which is used to adjust aircraft performance automatically by the flight control system or by the pilot.
