Conveying and release device with cartridge presence indicator

A method for verifying a an aeronautical conveying and release device actuated by a pyrotechnic cartridge that comprises:

• a housing provided in a body having a recess, the recess having an open end and a bottom,
• a cartridge adapter capable of closing the recess and forming a chamber capable of housing the cartridge, and
• a cartridge presence indicator mounted, on an outer face of the body, movably between a first position and a second position,
• the cartridge adapter having a bolt capable of being screwed into the housing so that:
• in the presence of a pyrotechnic cartridge, the bolt can be screwed to a first depth where the bolt abuts against the pyrotechnic cartridge, the pyrotechnic cartridge being in abutment against the bottom of the recess, and
• in the absence of a pyrotechnic cartridge, the bolt can be screwed to a second depth greater than the first depth, and
• the bolt at the first depth prohibits the first position for the cartridge presence indicator, while the bolt at the second depth leaves the cartridge presence indicator free to move, the method comprising at least the following group of steps:
• 1a) raising the cartridge presence indicator,
• 1b) screwing the cartridge adapter into the housing until abutment,
• 1c) releasing the cartridge presence indicator, and
• 1d) determining whether the cartridge presence indicator reaches the first position.
