Summary

• What is new: A fast, real-time algorithm to compute the gliding reachable region (GRR) and another to estimate the minimal altitude needed to glide to an airfield accounting for obstacles.
• Why this is important: Pilots need to estimate reachable landing sites and required altitudes in the event of a total thrust loss.
• What the research proposes: Developed algorithms using optimal control formulation and simplified aircraft dynamics, solved numerically to determine GRR and minimal re-entry altitude.
• Results: Algorithms can run in real time during flight, accounting for obstacles and wind, providing paths with minimal altitude loss.
