Patent ID: 10600328

Abstract:
An enhanced flight management system and flight management method directed to improved guidance in unstable approach scenarios. The method includes receiving and processing a published arrival procedure (PAP), a published glide path (PGP), landing parameters, and real-time aircraft sensor data to determine a an actual approach profile, and whether the aircraft is following the reference approach profile. Approach stabilization criterion are determined, including, (i) a wind corrected air mass flight path angle (WC FPA) at the IMC; (ii) a vertical speed at the wind corrected air mass flight path angle (VS IMC); (iii) a wind corrected air mass flight path (WC FPA) angle at the VMC; and (iv) a vertical speed at the wind corrected air mass flight path angle (VS VMC). The method also determines whether an IMC criterion profile and a VMC criterion profile stabilizes the actual approach.
