Water ballast loads in fin tank (optional)
The determination of the ballast quantity carried in the fin tank (m
FT
) is done with
the aid of the diagram shown on the next page.
The maximum capacity of the fin tank is 7.8 kg/Liter (2.06 US Gal, 1.72 Imp. Gal).
Note:
When determining the useful load in the fuselage the quantity of water ballast
in the fin must not be taken in account because of flight mechanic reasons
Example:
Assumed ballast load in wing tanks:
100 kg/Liter, 220 lb
(46 kg in the inner wing tanks, 54 kg in the middle wing tanks)
Permissible fin tank ballast load according to diagram on the following page
m
FT
= 2 kg/Liter
since it is only possible to fill full liters.
