3.9 EXTREME SITUATIONS
CAUTION: Due to high resistance of the Snake XX against both side and
front collapses, we strongly recommend not to provoke such situations
during safety trainings. Inducing collapses can be very hard to
impossible in standard way, while unconventional attempts can result in
extremely violent and dynamic behaviour.
PROVOKING EXTREME SITUATIONS SHOULD TAKE PLACE ONLY
DURING SAFETY TRAININGS UNDER SUPERVISION OF A QUALIFIED
INSTRUCTOR!
WHILE UNDER EXTREME CIRCUMSTANCES THERE IS HIGH
PROBABILITY OF TOO STRONG OR TOO HASTY STEERING INPUTS.
THAT'S WHY YOU SHOULD ALWAYS EMPLOY GOOD JUDGMENT, STAY
CALM AND TAKE MEASURED ACTIONS!
Since all actions required to exit or prevent dangerous situations are
typical and pilots flying Snake XX should already have proper
experience, we are going to describe only the characteristic features of
the Snake XX. Description of standard methods dealing with extreme
situations can be found in textbooks.
3.9.1 Side collapse
When the trimmers are fully opened or the speed system is engaged,
collapses practically do not occur and can be induced only by a very strong
turbulence.
Still, if it happens, a little counter-steering is enough to keep the canopy on
course. Under normal conditions with collapses up to 50% of the wingspan,
Snake XX will reinflate instantly and spontaneously. If not, you should aid this
process by application of brake on the collapsed side.
3.9.2 Symmetric collapse (frontstall)
The reflex profile of the Snake XX makes it practically impossible, especially
at higher speeds.
During tests we succeeded in creating this situation only with fully closed
trimmers and using special measures. Such forced collapses can lead to
extremely deep collapses, so recovery will require decisive pilot action (short
and equal application of both brakes).
3.9.3 Full stall and negative spin
May happen only as a result of serious neglect or intentional action of the
pilot. You have to be careful when flying at low speeds until fully familiar with
brake operation.
Wing recovers spontaneously in initial phase of stall, otherwise use standard
procedures.
