DO-178B DEACTIVATED code is executable (binary) software that will not be executed during runtime operations of a particular software VERSION within a particular avionics box; however the code may be executed during maintenance or special operations or be executed within a different or FUTURE version of the software within a different configuration or avionics box. Unlike dead code (see above), deactivated code may be LEFT in the SOURCE baseline. Special DO-178B deactivated code aspects must be followed. These are fully described in our member's DO-178B classes;
