Systems and methods for generating a recapture path for an aircraft

Abstract:

Provided are enhanced flight guidance systems and methods for an aircraft. The method includes recognizing when the aircraft is in manual operation and an active flight path is different than the planned flight path. An interrupt is received and categorized as one of (i) obstacle, (ii) equipment/fuel, or (iii) pilot health monitor. A managed mode begins, including identifying a rejoining leg of the planned flight path at which to rejoin and a location on the rejoining leg at which to rejoin. A recapture path strategy is selected from (i) lateral, (ii) vertical, and (iii) mixed lateral and vertical. A recapture path to the location on the rejoining leg is computed. The computed recapture path includes speed targets and configuration requirements at dedicated points along the recapture path. Aircraft state data along the recapture path is predicted and guidance controls for the aircraft along the recapture path are generated.
