AMC Acceptable means of compliance

## AMC1 SPO.IDE.A.155 Flight data and cockpit voice combination recorder

GENERAL

When two flight data and cockpit voice combination recorders are installed, one should be located near the flight crew compartment in order to minimise the risk of data loss due to a failure of the wiring that gathers data to the recorder. The other should be located at the rear section of the [aeroplane](https://avioverse.aero/glossary/easa/aeroplane), in order to minimise the risk of data loss due to recorder damage in the case of a crash.
