Asymmetric deflation
In the event of encountering strong turbulence and suffering an asymmetric deflation (collapse
on one side), the Vantage will promptly and easily re-inflate without interference from the pilot,
but the course might alter slightly. This might be unwanted close to the ground or other gliders.
Maintain your course by weight shifting away from the collapsed side. This action can be aided
by applying a little force on the brake opposite to the deflation. This will normally be sufficient.
However, if the deflation fails to come out, pump the deflated side with a firm and smooth
pumping motion. Let the glider regain its flying speed after it has re-inflated.
Symmetric deflation
A symmetric (frontal) deflation will come out promptly without pilot input. The glider will regain
airspeed with a small surge. If counter braking, be careful not to over-correct.
Cravat / glider wrapped around lines
A cravat occurs after a severe deflation when the wingtip becomes trapped in the glider lines. It
is extremely unlikely to occur on the Vantage. Nevertheless, the pilot should be familiar with
the procedure for correcting it. Counter brake and/or weight shift and pump the brake on the
tangled side. On all Gin gliders, there is a separate stabilizer/winglet main line that goes down
to the C riser. This line usually comes slack in the event of a cravat. Pull it down completely
until it comes tight and the cravat normally comes out.
Cascade of events
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.
Flat spin
In normal thermalling flight, you are very far from the limits of a flat spin. Nevertheless, should
this occur, just let up the brakes and wait for the glider to surge forward.
Full stall, dynamic stall
This is an extreme manoeuvre and there should never be any need to perform one.
