Ballast Box In The Fin - DG Flugzeugbau DG-1000 Flight Manual

6.8.7

Ballast box in the fin

a) Compensation of the C.G. shift due to the rear pilot:
The ballast box can accommodate max. 4 weights of 2,4 kg mass (heavy weight)
and 2 weights of 1,2 kg mass (light weight), so the max. mass is 12 kg.
The number of weights can be determined by the following table:
Mass of rear pilot Number of trim
kg lbs.
55 121
65 143
75 165
85 187
95 209
105 231
Warning: When flying solo the ballast box must be emptied, except see b)!
Otherwise you will fly with a dangerous C.G. position.
If the ballast box is filled up, the min. cockpit load in the front seat is raised by
35 kg (77 lbs.).
The resulting value (min. cockpit load in front seat from weighing without
ballast + 35 kg) must be entered in the table on page 6.7 as value XX and also
on the placard at the indication lights for the fin tank on the front instrument
panel.
When using the trim weights make sure not to exceed the max. weight of 750kg
(1653 lbs.) Category „U" or 630kg (1389 lbs.) Category „A".
b) Trim-possibility for heavy pilots:
The ballast box may be used for this purpose too.
One trim weight of 1.2 kg raises the min. load in the front seat by 3.5 kg (7.7
lbs.).
One trim weight of 2.4 kg raises the min. load in the front seat by 7 kg
(15.4 lbs.).
Example for combination of a) and b)
(1 kg= 2.2046 lbs):
Min. cockpit load of the glider: 70 kg
Mass of the front pilot:
Mass of the rear pilot:
Total amount of trim ballast:
This means that the ballast box can be filled completely for this example.
Higher pilot masses can't be compensated.
