Patent number: 12515814Abstract: Methods and systems for testing an aircraft in-flight are described herein. The method can include receiving a test deck including one or more test cards, with an individual test card including an ordered list of points. For an individual test card, points of the ordered list of points can be performed, a status for the performed points of the ordered list of points can be assigned, a current fuel value for the aircraft can be received, and the current fuel value can be compared to an expected amount of fuel required to perform the remaining test cards. In response to the comparison indicating that the current fuel value is not sufficient for the remaining test cards, the method can include modifying the test deck at least until the current fuel value is sufficient for executing a subset of remaining test cards.Type: GrantFiled: October 4, 2022Date of Patent: January 6, 2026Assignee: Boom Technology, Inc.Inventors: Jeffrey Mabry, David Hunter, Eric Dowty
