Abstract: A flight simulator adapted for a family of aircraft may include a computer having a hardware unit common to the family of aircraft and capable of carrying out a function by implementing a software program that is supported by a nonvolatile memory of a module. The module is electrically and mechanically connected in a removable manner to the hardware unit and has a plurality of independent memories. Each of the memories stores a specific software program for implementing the function related to a given type of aircraft. A controllable component of the module may select, when the module is connected to the hardware unit, one of the memories whose software program is then implemented by the hardware unit.

Abstract: The present invention relates to a flight simulator adapted for a family of aircraft and comprising at least one hardware unit (2) common to the aircraft of the family and capable of carrying out at least one function by implementing a software program which is supported by a nonvolatile memory (M1, M2, M3, M4) of a module (3), said module (3) being removably connected to said hardware unit (2).
