Abstract

For improving 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 and/or braking parachutes attached to the seat and furthermore initiates separation of the person from the ejection seat, it is provided that while the connection between aircraft and ejection seat exists, current flight data for the aircraft are fed via a data bus to an ejection seat computer situated on the ejection seat and once the ejection seat has separated from the aircraft the movement data for the ejection seat in space are collected and forwarded to the ejection seat computer by a navigation platform attached to the ejection seat and, that the relevant flight data for the ejection seat are calculated in the ejection seat computer starting with flight position data for the aircraft at the time the ejection seat separated and when pre-established limits are met the stabilizing and/or braking parachutes are deployed and/or the seat/person separation is initiated.
