o Additional pilot weight is required to move the CG forward
towards the optimum position (75% from the front position).
o Permanent ballast can be removed from the cavity in the tail,
in accordance with aircraft Maintenance Manual, to reduce
the minimum cockpit weight. In this case a new weight and
balance must be performed.
White coloured cells
White coloured cells indicate the weight requires in the non-expendable
tank to adjust the CG to the optimum aft 25% position.
Blue coloured cells
Blue coloured cells indicate the maximum weight requires in the non-
expendable is insufficient to reach the optimum CG position. Refer to
the CG calculator to ensure the forward CG limit is not violated.
CAUTION: Flying on the aft limit is not recommended. Winch
launching with the CG in the caution band is not
recommended. Refer to Section 4.5.7
CAUTION: When flying the aircraft with the CG on the forward limit
with ballast in the main wing tanks and expendable rear
tank, all of the ballast in the main wing tanks and the
expendable tail tank must be dumped once the dumping
process has started. The reason for this is that the rate
of dumping of the rear expendable tank is higher than
the main tank, moving the CG outside the forward limit
during dumping. Once all of the ballast has been
dumped the CG will return to the forward limit.
WARNING: Flying outside the allowable CG is not allowed. Moving
the CG rearwards reduces the lateral stability of the
aircraft.
