Abstract
A flight recorder (MPV) is contained within a two-walled chassis (11, 13) of which the walls are separated by a fire-resistant material (12). The memory means consist of hybrid circuits (H1-H8) of the EEPROM type. These are associated with a control card that may act as a fuse, The hybrid circuits (H1-H8) are mounted so as to be pressure-resistant. The flight parameters are alternating recorded on two memory cards (MC1 and MC2) and also in their hybrid circuits.
