Patent number: 10486823Abstract: An aircraft is provided that includes a fuel storage tank for aviation fuel, and avionics systems interconnected by an avionics bus. The fuel storage tank receives aviation fuel during a fuel uplift for a flight according to a flight plan that includes and depends on a predicted fuel burn determined based on a reference lower heating value (LHV) of the aviation fuel. The avionics systems include temperature and density sensors, and a flight management system (FMS). The temperature and density sensors measure respectively the temperature and density of the aviation fuel. The FMS receives the measurements, estimates an actual LHV that is different from the reference LHV based on the measurements, and determines an adjusted predicted fuel burn for the flight based on the predicted fuel burn and the actual LHV. The FMS displays the adjusted predicted fuel burn and enable adjustment of the flight plan based thereon.Type: GrantFiled: October 16, 2017Date of Patent: November 26, 2019Assignee: The Boeing CompanyInventors: Jose A.

Patent number: 10302451Abstract: Systems and methods for enhancing takeoff performance by displaying symbology representing an initial pitch angle target that optimizes the amount of payload that can be carried by an airplane. This is accomplished by determining an optimum initial pitch angle at rotation during takeoff which is associated with an optimum ratio of the takeoff safety speed to the stall speed that satisfies a specific set of climb/obstacle constraints. Targeting this optimum initial pitch angle allows the maximum takeoff gross weight that corresponds to the optimum takeoff safety speed/stall speed ratio to be selected.Type: GrantFiled: February 20, 2018Date of Patent: May 28, 2019Assignee: The Boeing CompanyInventors: Geun Il Kim, Jose A.
