  • Optical device for estimating a center of gravity of an aircraft
    Patent number: 10627304
    Abstract: A system includes a signal generator that is configured to generate a first electrical signal. The system also includes a light source configured to generate a light beam based on the first electrical signal. The light source is also configured to direct the light beam towards a structural member of an aircraft. The system also includes a photoelectric sensor configured to receive a reflected light beam and convert the reflected light beam to a second electrical signal. The reflected light beam corresponds to a portion of the light beam that is reflected from one or more optical reflectors coupled to the structural member. The system also includes circuitry configured to estimate a location of a center-of-gravity of the aircraft based on a timing difference between the first electrical signal and the second electrical signal.
    Type: Grant
    Filed: January 31, 2018
    Date of Patent: April 21, 2020
    Assignee: THE BOEING COMPANY
    Inventors: Sina S. Golshany, Martin M. Withington, Lowell B. Campbell, David A. Rathke, Tarek H. Elghoroury, Matthew W. Orr, Gnanulan Canagaratna

  • System and method for determining a load capability
    Patent number: 10337906
    Abstract: In a particular implementation, a method includes generating an initial weight estimate associated with an aircraft based on a reference operational empty weight (OEW) and at least one of a latitude or an altitude of the aircraft at a first location. The reference OEW is predetermined at a second location that is distinct from the first location. The method includes determining an additional load capability of the aircraft based on a difference between the initial weight estimate and the reference OEW. The method further includes generating an output that indicates the additional load capability.
