This feature should only be used when
•
it can be foreseen that no frequency changes will be
required (i.e. when using only limited airspace near one
airport, e.g. for circuit pattern training flights), and
•
the crew is familiar with the energy saving mode.
In all other cases this feature shall be deactivated, in order to
prevent the usage of wrong frequencies and to avoid
confusion of pilots not aware of the energy saving mode.
