Filling procedure
1.
Determine the quantity of water ballast to be carried. The quantity
of water ballast in the tail is calculated using the graph in
Fig 4.5.6-1.
2.
Determine the quantity of water to be loaded in each tank. In the
21 m configuration the tips
must
be filled if water is carried in the
main tanks. If tanks will be partially loaded water must be loaded
in the following sequence:
i.
21 mtips (if fitted)
ii.
Main wing tanks
iii.
Fuselage tank (if fitted)
3.
Open the dump valve in the cockpit, and ensure the expendable
tail tank is empty by following the procedure given in the daily
inspection check list.
4.
Close the dump valve in the cockpit.
5.
Fill the 21 mtips (if fitted). Filling can be done through the dump
valve, using filling equipment allowing a maximum of 0.1bar
pressure.
6.
Fill the main tanks via the filler caps on the top surface
7.
The expendable tail tank can be filled using the bottom filling port
on the right hand side of the fin. Ensure that the quantity water in
the expendable tank is in relation to the quantity of water in the
main tanks.
8.
Fill the non-expendable tail tank as follows:
•
Calculate the quantity of ballast for the non-expendable tank
using the calculations explained in Sec 6.4.
•
Seal the dump holes (3 mm holes on right hand side of fin)
with a sealing tape to up to the required level.
