Towing; Motored Flight / Aerobatics; Extreme Flying Manoeuvres; Collapse - Nova RA Betriebshandbuch

43
The final glide during the landing approach should be straight and not marked
by steep or alternating turns as these can result in a dangerous pendulum ef-
fect near the ground.

Towing:

The NOVA RA has no special towing characteristics, although a relatively low
angle of attack and thus low tow tension should be maintained during launch
and the initial part of the tow.

Motored Flight / Aerobatics:

Contact the manufacturer or importer for the current legality of motorized flight.
The NOVA RA is not designed to be used for aerobatics.

Extreme Flying Manoeuvres:

Collapse:

A negative angle of attack will cause the NOVA RA to collapse (e.g. in turbulent
air).
If one wing tucks, straight flight should be maintained by "correcting for direc-
tion" - braking gently on the inflated side.
In case of a big collapse, this braking should be applied very carefully to avoid
stalling the remaining inflated wing. The pilot's "correction for direction" can be
aided by a "pumping out of the deflation", a slow, long pumping action on the
brake of the deflated side of the wing helps the canopy to re-inflate.
If the pilot does not correct, the NOVA RA usually self-recovers. However, if it
does not self recover and the pilot does not correct the canopy can enter a
stable spiral dive.

Line over:

The pilot stabilizes the glider by gently applying the brakes. Without the pilot's
action the line over will result in a stable spiral dive.
Here are various possibilities to untangle a line over:
- pumping the collapsed side.
- pulling the stabilizer line or lines causing problem.
- should both measures fail, it is possible to untangle the line over by inducing
a full stall. This manoeuvre, however, should only be carried out by advanced
pilots with experience in extreme flight situations and with sufficient altitude
available.
