In FAST-OAD mission module, :ref:`segments<flight-segments>` are the base building blocks used in the :ref:`mission definition file<mission-definition>`. They are implemented in Python and FAST-OAD offers a set of segment types that allows defining typical aircraft mission profiles.
Yet, the need for some other segment types may occur. This is why FAST-OAD mission module is designed so that any user can develop new segment types and use them in a custom mission file.
