Patent number: 11480980Abstract: An anti-spin system for an aircraft can include an anti-spin module configured to execute a computer implemented method. The method can include receiving flight data from one or more aircraft flight data systems, determining if the aircraft is near stall or in a stall using the flight data, and determining if the aircraft is in uncoordinated flight while near stall or in a stall to determine if the aircraft is near spin or in a spin using the flight data. If the aircraft is determined to be near spin, the method includes at least one of sending an alert to a warning indicator in a cockpit to warn the pilot of a spin or near spin condition, or sending a signal to an automated control system for inputting automatic control to the aircraft to avoid a spin by coordinating the aircraft or avoiding a stall while uncoordinated.Type: GrantFiled: September 19, 2018Date of Patent: October 25, 2022Assignee: Rosemount Aerospace Inc.Inventors: Brian Brent Naslund, John D.
