In case the spin is allowed to develop for some time, the NOVA XYON
surges forward on one side and a big and impulsive asymmetric tuck
can occur. If so brake gently to stop canopy surging, correcting tuck :
see " tucks ".
Wingover :
To induce a wingover the pilot flies consecutive alternating turns to
steepen the angle of bank. The NOVA XYON only tucks when a high
angle of bank is attained.
Attention: A turn with more than a 60 degree angle of bank is illegal
aerobatics !
Front stall
If the pilot pulls both A-risers a front-stall is induced: the entire leading
edge tucks and the canopy generally forms a frontal horseshoe. To
recover from a front-stall apply steady brake on both sides.
THE SINK RATE FROM THIS MANOEUVRE CAN BE VERY HIGH.
ENSURE YOU HAVE ENOUGH HEIGHT.
A FRONT STALL ON THE XYON COULD BE STABLE. THEREFORE
THE PILOT MUST ACTIVELY RECOVER FROM IT.
Line over :
If for any reason, lines are tangled or looped around the canopy during
flight the following action should be taken:
Maintain straight flight by gently and feel fully correcting for direction!
Check the situation carefully and once the line(s) looped around the
canopy, is/are identified pull it/them gently to untangle.
Pumping of the controls may also have enough effect, try it first.
If a very large unrecoverable collapse and line over occurs, it may be
possible, only if sufficient altitude is available, to clear the problem by
entry and safe recovery from a full stall. If insufficient height is available
(300m/1000ft), or if it any doubt, the pilot should strongly consider
reserve deployment.
