   You can recognise a deep stall by the glider getting "mushy" and the airflow around your

ears decreasing. The glider may also compress spanwise. Flying in strong turbulence or

exiting a deflation with too much brake applied can cause this situation. A wet glider also has

a higher deep stall tendency, and you should do everything you can to avoid flying in the rain.

If you do pass through some rain never make big ears! Open the trimmers until you are

confident that the wing has dried out.

WARNING: Never apply the brakes, including any wraps taken, in a deep stall.

Full stall (dynamic stall)

The full stall happens when the wing partially deflates and loses its arched shape. It is

triggered when the maximum possible angle of attack is exceeded. The most common cause

is going below the minimum speed or flying near the minimum speed combined with the

effects of turbulence.

   In full stall, the speedriding glider loses its forwards travel, surges backwards and deflates. If

the brakes are held down, the canopy comes up over the pilot again. The result is an almost

vertical descent with a sink rate of approx. more than 20m/s.

WARNING: Never fly stall or full stall with the Nano 4.

Spin

The spin is a stable flight maneuver, in which one side of the canopy stalls, while the other

side continues to fly forward. The glider turns around the stalled side of the wing.

WARNING: Never fly spins with the Nano 4.

Other tips for dangerous situations

Cascade

Many reserve deployments are a result of a cascade of over-corrections by the pilot. Please

note that over-corrections are often worse than no input at all.

Emergency steering (rear riser steering)

If for some reason the brake lines are not working, e.g. if the knot on the brake handle has

come undone or a brake line is defective, the Nano 4 can also be steered and landed using

the rear risers.

   In this case, stall happens more quickly and the pilot must compensate for the changed

flight behaviour by pulling carefully on the risers.

Flying in the rain

We strongly advise you not to fly in the rain on any speedriding glider including the Nano 4. If

you do fly in the rain, be aware that you will have a greater risk of entering a deep stall. It is

wise to open the trimmers after passing through rain until you are confident that the glider is

flying normally, and has preferably dried out so that there is no longer any risk of deep stall.
