Abstract:
A method for rescuing a person sitting in an ejection seat that has ejected from an aircraft in an emergency, wherein depending on data collected by measuring apparatus arranged on the ejection seat a control device initiates deployment of stabilizing or braking parachutes attached to the seat and furthermore initiates separation of the person from the ejection seat, said method including the steps of:while the connection between aircraft and ejection seat exists, feeding current flight data for the aircraft via a data bus to an ejection seat computer situated on the ejection seat;after the ejection seat has separated from the aircraft, collecting movement data for the ejection seat in space;forwarding said movement data to said ejection seat computer by a navigation platform attached to the ejection seat;calculating the relevant flight data for the ejection seat in said ejection seat computer starting with flight position data for the aircraft at the time the ejection seat separated; andeffecting at least one of deploying stabilizing or braking parachutes and initiating separation of a person from said ejection seat when said data collected by said ejection seat computer meets predetermined threshold values of selected parameters.
