Methods and apparatuses for autonomous flight termination

A flight safety system, comprising:

• an aerial vehicle;
• and
• two autonomous flight safety assemblies onboard the aerial vehicle, each of the two autonomous flight safety assemblies comprising:
• a sensor configured to sense information related to flight of the aerial vehicle;
• and
• a processor operably coupled to the sensor and configured to:
• analyze the information to determine a projected flight path of the aerial vehicle;
• and
• generate an onboard flight termination signal if the projected flight path indicates that the aerial vehicle will leave a safe window.

A method for determining safety parameters of an aerial vehicle, comprising:

• sensing first information related to flight of the aerial vehicle and sensing second information related to the flight of the aerial vehicle using one or more sensors;
• determining two independent instantaneous impact points for the aerial vehicle by independently analyzing each of the first information and the second information;
• and
• generating two independent onboard flight termination indicators, each responsive to one of the two independent instantaneous impact points being within a region to be protected for a projected flight path.

A method for determining safety parameters of an aerial vehicle,

• comprising:
• sensing first information related to flight of the aerial vehicle and
• sensing second information related to the flight of the aerial vehicle using one or more sensors;
• analyzing the first information and the second information with one or more processors to determine a projected flight path of the aerial vehicle;
• and
• generating an onboard flight termination signal if the projected flight path indicates the aerial vehicle will leave a safe window.
