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 Figure 4.5-2.
2. Determine the quantity of water to be loaded in each tank. In the
18 m configuration the tips must be filled if water is carried in the
main tanks. If the tanks are partially loaded, water must be
loaded in the following sequence:
•
18 m tips (if fitted)
•
Main wing tanks
•
Fuselage tank (if fitted)
3. Open the dump valve in the cockpit and ensure that 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 18 m tips (if fitted). Filling can be done through the dump
valve using filling equipment allowing a maximum of 0.1 bar
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 left-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 Section 6.
•
Seal the dump holes (3 mm holes on left hand side of fin)
with a sealing vinyl sticker to up to the required level.
•
Add water ballast using the filling port(s) on the left-hand
side of the fin. Refer to section 7.8.4.2 for details.
