Safety system for an aircraft

A safety system for an aircraft for storing flight and voice data relevant for reconstructing crashes, comprising:

• a data collection device which is connected to sensors of the aircraft and by means of which relevant flight data and voice data of the aircraft can be collected and stored by a black box-terra which is substantially inseparably attached to the aircraft, the black box-terra being accommodated in an impact-proof and fireproof housing;
• a data splitter, wherein the flight data and voice data to be stored in the black box-terra can be delivered in parallel to at least one first and one second black box-water and that the black boxes-water are likewise designed for storing the collected flight and voice data, wherein the black boxes-water comprise:
• a floating body or are designed to be self-floating;
• detachment means in each black box-water which detach the black boxes-water from the aircraft immediately before, during or after a crash of the aircraft, upon an automatic or manual activation and upon the occurrence of different detachment criteria, whereupon the black boxes-water are designed to emit an alarm signal locatable by a satellite;
• and
• evaluation means in each black box-water, to which electric signals concerning different detachment criteria can be supplied and which, depending on which detachment criterion or which detachment criteria is/are relevant for the respective black box-water, are designed to deliver a detachment information to the detachment means for detaching the black boxes-water at different times.
