Revision – 4.5.7.6
Important note:
o
Before the wing water tanks are filled, it must be checked (with
dump valves opened) that both drain plugs open up equally.
Leaking (dripping) valves are avoided by cleaning and greasing the
plugs and their seats (with valves opened). With closed dumping
lever in the cockpit the valves must close fully. Leaking (dripping)
valves are avoided thereafter, with valves closed, pulling the drain
plugs home with the threaded tool used to attach the tailplane.
o
There is little point in loading much water ballast if the average rate
of climb expected does not exceed 1.0 m/s (197 fpm). The same
applies to flights in narrow thermals requiring steep angles of bank.
o
If possible all water ballast is to be dumped before conducting an
off field landing.
