-- asymmetric stall

This can happen when turning in a thermal at low speed (near the stall point) when you
want to close the turn and you don't rise the outer brake but you apply more input to
the inner brake causing an asymmetrical stall (half wing will fly forward and the other
backwards) When this happens to regain stable flight you have to rise the inner brake
and the wing will surge forward. Depending on the flat spin the surge can be quite large.
Use the brakes to stop the surge. Another option is to achieve a full stall and exit in a
symmetrical way to avoid any twist. Do this with plenty of height above ground.

-- deep stall

It is possible that a glider goes into deep stall. This maybe caused in different situations:

when flying the wing wet, and after a slow exit from a B stall or after a symmetrical or
asymmetrical tuck. The result are that even when the canopy looks fully inflated is not
flying forward. When this happens rise both hands. This action may cause to regain flight.
If nothing happens after several seconds pull the A risers or use the speed system to
regain normal flight.

Make sure that the wing is back to normal horizontal speed before using the brakes.
Never fly under the rain or with a wet canopy since these may cause a deep stall situa-
tion. When flying under rain land immediately.

> bad weather flying

We advise not to fly in bad weather. Before going flying you should check the weather
forecast

& always ask more experienced pilots about the conditions expected for the day.

Never fly if weather conditions are inappropriate If you are already in the air then get
down safely before it's too late! Always be aware of the weather changing

&

if in case

of doubt land as quickly as is safely possible.

Even though the FENIX is EN C certified this is not a guarantee against flying in turbu-
lent air.

> emergency procedures

& quick descent techniques

It may happen that you will need to descend very quickly and all pilots should do a train-
ing course (SIV) in a certified official school. This training is done with plenty of height
above water and a support boat. As a informative manner quick descent maneuvers are:

-- bigs ears

Big Ears is the simplest descent technique

& can be very useful for top landing.

Sit upright in your harness

& with the brakes in your hands reach up to the OUTSIDE 'A'

riser. Make sure that you have the correct line, and be careful not to pull down the whole
