+:code:`takeoff` segment
+=======================
+
+.. versionadded:: 1.5.0
+
+This segment is the sequence of `ground_speed_change segment`_, `rotation segment`_ and `end_of_takeoff segment`_.
+
+The parameters for this segment are the same as for its 3 components, except that:
+
+  - :code:`time_step` is used only for `ground_speed_change segment`_ and `rotation segment`_.
+  - time step for `end_of_takeoff segment`_ is driven by the additional parameter :code:`end_time_step`
+  - target speed at end of `ground_speed_change segment`_ is driven by the additional parameter :code:`rotation_equivalent_airspeed`
+  - the target of :code:`takeoff` segment is the target of `end_of_takeoff segment`_, meaning it sets the safety altitude.
