Flight manual DG-800S
DG-800S ballast chart
(for 6.8)
to determine the max. amount of ballast in the fin tank.
Curve 1
= ballast in the wing tanks
Curve 2
= total ballast (wing tanks and fin tank)
Example:
From the diagram on page 6.7 a max. allowable ballast of 134 kg
(wings + fintank) was determined. Curve 2 of the above diagram gives a fin
ballast of 4.6 kg. The crossing point of the horizontal line with curve 1 gives the
corresponding amount in the wing tanks of 129.4 kg.
Note:
The fin waterballast determined from this diagram compensates only 80
% of the C.G. move due to the wing ballast, which will insure that in case of
leaking wing tanks, the rear in-flight C.G. is kept in the limits.
1 kg = 2.2046 lbs.
3.785 kg (l) = 1 US gal.
