Air from the tanks escapes through the overflow pipe that runs down to a point an the
underside of the wing near the root. When flying with water-ballast the connecting-tape
that covers the gap between fuselage and wings, should be folded back on the
underside in the region of the spar, so that any excess water which may appear runs out
rather than down into the fuselage.
During long flights at an air temperature of 0 ° C (32 ° F) the water-ballast must be
jettisoned because there is danger of collapse of the ballast tanks. When a field landing is
to be made the water-ballast must be jettisoned.
The glider must not be parked over-night with water-ballast on board. If the glider has to
be towed for a long way on the ground with water-ballast on board, the tanks should be
emptied.
When de-rigging the water-ballast tanks will empty themselves through the wing root
connecting pipes.
Stalling Characteristics
Warning of the stall occurs at a speed of 32-35 kts (depending on wing loading), when the
top of the tail unit begins to shudder. If the stick is pulled back even further, the glider
"mushes" but, remains controllable, it being possible to make turns up to an angle of
bank of 20' without the wing dropping away. If the stick is released the glider returns
immediately to the normal flying attitude. If the stick is pulled back quickly, the nose will
drop away but any tendency for a wing to fall can be controlled by the rudder.
Aerobatics
Permitted maneuvers and speeds at which they should be initiated:
Loop ..........................................................................................................................92 kts
Chandelle...................................................................................................................92 kts
Steep turn................................................................................................................. 65 kts
Lazy eight ..................................................................................................................65 kts
Spins:
From the fully stalled position, put on full aileron and rudder (crossed). Keep the stick
back. To stop the spin centralize or release one of the controls. Height lost per rotation
is approximately 220 ft. The speed reached when leveling out is about 86 kts.
Maximal positive g l 5,3.
Manoeuvres that involve negative g loads are prohibited.
Unorthodox manoeuvres are likewise prohibited
