full balance is not warranted. Press

If the move line length is below 0 .4IPS, proceed with the balance according to the directions for th
particular aircraft and balance type. Note that the Balance Run Start-up screen substitutes the
HSGI
soft key for
CHART INFO
and provides a third row of soft keys containing
CHART INFO
and
MOVE LINE
. Use
MOVE LINE
to view the move line calculation.
Balance histories are recorded for fixed-wing aircraft just as they are for other rotor systems. Note that
the second (high-power) HSGI balance run is saved as the first balance run in the aircraft's balanc
history.
