1. A device, adapted to be used in an aircraft, for generating and storing aircraft breakdown data, comprising:
- means for detecting an aircraft breakdown condition and generating aircraft breakdown data in response thereto;
first memory means for storing said aircraft breakdown data at a number of addresses beginning at a first address, said first memory means being coupled to said detecting means via an address and data bus;
second memory means connectable to and removable from said address and data bus, said second memory means being non-volatile;
presence testing means for determining whether said second memory means is connected to said address and data bus;
means for generating a request that said aircraft breakdown data be copied from said first memory means to said second memory means so that said second memory means can be removed and moved to a location remote from said first memory means after said aircraft breakdown data has been copied into said second memory means;
means for copying said aircraft breakdown data from said first memory means to a number of addresses beginning with a second address in said second memory means upon said generation of said request, said copying means including;
means for reading and storing said first address beginning at which said aircraft breakdown data is stored in said first memory means, said second address beginning at which said aircraft breakdown data is to be stored in said second memory means, and said number of addresses of said aircraft breakdown data to be copied from said first memory means to said second memory means;
means for transferring a portion of said aircraft breakdown data stored in said first memory means at said first address to said second memory means at said second address;
means for periodically incrementing said first address in said first memory means and said second address in said second memory means; and
means for determining whether all of said aircraft breakdown data stored in said first memory means has been copied to said second memory means.

Abstract
Device for making use of information relating to the breakdowns detected by a central unit (2) of an aircraft, the unit being linked via an address and data bus (4) to a first memory (6) storing this information, comprising a second non-volatile memory (7) which is removable and connectable to said bus (4) and in which the information contained in the first memory (6) may be recopied so as to process it in a computing center.

7. An apparatus, comprising:
-
means for detecting an aircraft breakdown condition and generating aircraft breakdown data in response thereto; first memory means for storing said aircraft breakdown data at a number of addresses beginning at a first address, said first memory means being coupled to said detecting means via an address and data bus; second memory means connectable to and removable from said address and data bus, said second memory means being non-volatile; presence testing means for determining whether said second memory means is connected to said address and data bus; means for generating a request that said aircraft breakdown data be copied from said first memory means to said second memory means so that said second memory means can be removed and moved to a location remote from said first memory means after said aircraft breakdown data has been copied into said second memory means; a maintenance computer for coupling to said second memory means, said maintenance computer comprising means for automatically processing said aircraft breakdown data; and means for copying said aircraft breakdown data from said first memory means to a number of addresses beginning with a second address in said second memory means upon said generation of said request, said copying means including; means for reading and storing said first address beginning at which said aircraft breakdown data is stored in said first memory means, said second address beginning at which said aircraft breakdown data is to be stored in said second memory means, and said number of addresses of said aircraft breakdown data to be copied from said first memory means to said second memory means; means for transferring a portion of said aircraft breakdown data stored in said first memory means at said first address to said second memory means at said second address; means for periodically incrementing said first address in said first memory means and said second address in said second memory means; means for determining whether all of said aircraft breakdown data stored in said first memory means has been copied to said second memory means. - View Dependent Claims (8, 9, 10, 11, 12)
