We advise you to control the sink rate of the spiral to a maximum of 14 m per second. It is
possible to reach a much higher sink rate but the risk of blackout or stable spiral increase
proportionally with higher sink.
We do not recommend performing spirals with Big ears as this manoeuvre puts undue stress on
the canopy.
B-stall
The B-stall requires considerable physical strength and puts stress on the canopy. For this
reason we do not recommend the B-stall as a regular method of descent.
To enter the B-stall, take the B-risers just below the maillons and twist your hands while gently
pulling. It will be difficult at first, but become lighter the more you break the airfoil. Once
pulled, do not release immediately. The glider needs to settle into a stable B-stall before
releasing. On exiting the B-stall the
Atlas has a very gentle dive without deep stall tendencies.
We advise you to release the B-stall symmetrically with both hands in a decisive manner.
Full stall, dynamic stall
This is an extreme manoeuvre and there should never be any need to perform one.
The full stall on the Atlas is difficult to do, due to the long brake range and high brake pressure.
Do not take wraps with your brakes before entering a full stall. Keep your hands close to your
body during the stall, and lock them under your harness seat plate if necessary. In a stable full
stall, the canopy will oscillate back and forth. Before releasing the stall, raise your hands
slightly and evenly to fill the glider with air. If possible, let the brakes up when the glider is in
front of you to avoid excessive surge. The
Atlas will damp the surge on its own, but you may
counter brake the dive briefly for comfort if needed and then let up the brakes to regain
airspeed. Be careful to not stall the glider again when damping the surge.
Never attempt a stall and then change your mind and release the brakes, as the glider will surge
radically.
Deep stall (parachuting, stable stall)
The Atlas does not have a tendency to go into or stay in a deep stall. Should this nevertheless
occur, put your hands on the A risers and push forward to gain speed. On some modern
harness/accelerator setups, you can reach the speed bar without using your hands. If so, push
the speed bar. Never try to steer out of a deep stall. Don’t touch the brakes when you are in a
deep stall, you will risk stalling the wing completely. If you are very close to the ground you
should never try to exit a stable deep stall. The sink rate in a deep stall is normally below the
sink rate of a rescue parachute; therefore you should not risk collapsing or stalling the glider
near the ground when you are in a deep stall. It is better to hang upright in your harness and
prepare for a hard landing, similar to a parachute landing and be ready for a PLF. Don’t try to
flare before hitting the ground in deep stall!
You can recognise a deep stall by the glider getting "mushy" and the airflow around your ears
decreasing. This situation is usually achieved by flying in turbulence or exiting a deflation with
too much brake applied. A wet glider also has a higher deep stall tendency. If you pass through
