Autonomous emergency flight management system for an unmanned aerial system
First Claim
1. An autonomous emergency flight management system for an unmanned aerial system (UAS) comprising:
- a landing site selection module programmed with a first flight plan and disposed on said UAS, wherein said landing site selection module comprises a database of pre-programmed landing sites, wherein said landing site selection module comprises a proposed image of a first landing site for said first flight plan;
a health monitoring module disposed on said UAS, wherein said health monitoring module comprises a UAS location detector, a UAS fuel detector, and an impairment detector;
a landing site verifier module disposed on said UAS, wherein said landing site verifier module is in communication with a camera disposed on said UAS that produces an actual image of a first landing site, wherein said landing site verifier module compares the proposed image of the first landing site to the actual image of the first landing site to determine the existence of a deviation;
a flight control computer disposed on said UAS in communication with said landing site selection module, said health monitoring module and said landing site verifier module to determine viability of said first flight plan,wherein said flight control computer has capability to detect an anomaly in said first flight plan from said landing site selection module, said health monitoring module or said landing site verifier, and wherein said flight control computer will calculate a second flight plan if said anomaly is detected indicating that said first flight plan is not achievable.

Abstract
An autonomous emergency flight management system may find safe and clear landing sites for unmanned aerial systems (UASs) in emergency situations. Emergency flight management software may reside on an onboard computing system. The computing system may continuously look at internal databases and input from other systems (e.g., a global positioning system (GPS), camera, compass, radar, sonar, etc.), depending on what is available. The emergency flight management system may make decisions on its own without human intervention. For instance, a database may provide some local likely candidates for landing sites. Information associated with the candidates may include latitude, longitude, altitude for top of a building, etc. Position updates may be continuously provided from an autopilot or other suitable system.
