B line stall
While in the B-stall the glider has no horizontal speed and the
sink rate increases to about -8m/s. To enter the B-stall reach
for the B risers just below the maillons and pull both B line
risers symmetrically for about 20 cm. To exit the manoeuvre,
simultaneously release both risers quickly. On exit the ROOK2
2gently dives without deep stall tendencies.
Spiral dive
The spiral dive is the most demanding of all three manoeuvres
(Big ears, B-stall, Spiral) and should only be trained gradually and
always at high altitude. The spiral dive should be practiced and
learned on a SIV course under professional supervision.
To enter the spiral, weight shift to the desired side and gradually
apply the brake on the same side. Then let the wing accelerate
for two turns and you will enter the spiral dive. While in the spiral,
you can control your descent rate and bank angle by applying
more or less inner brake. Depending on how steep the spiral is
you may need to use also outer brake.
To exit the spiral dive we recommend that the pilot is in the neutral
weight shift position. If you release the inner brake, the wing exits
the spiral dive by itself. The ROOK2 has no tendency of a stable
spiral but you should be aware of the procedure for exiting a
stable spiral.
To exit a stable spiral dive, weight shift to the opposite side of
the turn and apply the outer brake until feeling the deceleration of
the wing rotation. Then release the outer brake and let the glider
decelerate for the next couple of turns. To avoid a big pendulum
movement after exiting the spiral, apply a short brake input on
the inner side before the glider exits the spiral.
Warnings (Spiral dive):
• There is a possibility of losing consciousness while in the
spiral dive. Never make a spiral with more than 16-18m/s
sinking speed.
• In fast spirals it may be necessary to apply the outer brake to
begin exiting the spiral dive.
• If practicing the spiral dive low, a pilot may not have enough
altitude or time to safely exit this manoeuvre.
Winch launch
The ROOK2 is easy to launch using a winch and has no special
characteristics considering this kind of launching. To practice this
launching technique special training is needed and you have to
be aware of the procedures and dangers, which are specific for
winching. We do not recommend using any special towing device
which accelerates the glider during the winch launch.
Aerobatics
The ROOK2 was not designed for aerobatics, therefore, these may
not be performed on this glider. In addition to this, any extreme
manoeuvres place unnecessary stress on the glider and shorten
its lifespan.
Primary controls failure
If for any reason you cannot use the brake lines, you have to pilot
the wing to the landing place by using weight shift. Weight shift
should be enough to safely land the glider. You can also use the C
risers to control and steer the wing. Be careful not to over-handle
the glider by using the C riser technique when steering. By pulling
the C risers too strong you can cause a stall or a negative spin.
Land your glider at trim speed without using the C risers, to avoid
over-handling the glider low above ground. We recommend using
weight shift.
Landing
Similarly to the take-off, the ROOK2’s landing characteristics are
easy. In turbulent conditions it is advisable to apply about 15%
of the brakes, to increase stability and the feeling of the glider.
Before landing, adopt the standing position as this is the most
effective and the safest way to compensate the touch down with
your legs. Again we recommend training the landing manoeuvre,
as it might be useful to be able to land in small places, especially
in an unknown cross country terrain. Learn to evaluate the wind
direction by observing the signs on the ground and also your drift
while making turns. This proves to be useful for cross country,
when landing outside of your usual landing field. Another advice
we suggest taking into account in stronger winds is to go higher
for the landing fields and thus assuring you reach them. Likewise,
always look for possible alternatives downwind.
