SIV AND ACRO COURSES

The exercises are adjusted to individual ability and confidence. The Acrobatics are built up as an understanding of the wings dynamic energy is gained.

S.I.V. and Acro Courses in Nepal are run by David Arrufat and Herve Cerruti They came fourth in the Redbull Vertigo Acro competition. www.paragliding-nepal.com 3 day 300 Euro The courses can take place at any time during the flying season (from end october to may), with a minimum of 3 peoples. 28th-30th Oct 2011 15th-17th Nov 2011 6th- 8th Dec 2011 24th-26th Dec 2011 5th- 7th Jan 2012 16th-18th Jan 2012 03rd-05th Feb 2012 17th-19th Feb 2012 26th-28th Feb 2012 3rd-5th March 2012 Course includes 2 instructors, radio guidance video analysis, theorique course rescue boats on the lake. your SIV video on a CDROM, a document assessing your performance and level, a Blue Sky paragliding shirt.

 

Evening briefing Prepare harnesses - remove back protection and flying instruments - check reserve systems. Morning Start 8.00am start - Issue Lifejackets and radios. Three flights per day allow you to move through a progression of exercises. Lunch beside the lake. Evening Video debriefing

EQUIPMENT Wear a life Jacket. Take off sunglasses. Radio in waterproof bag. No flying instruments. Reserve parachute and know how to use it Remove the back protection from your harness as it will make you float upside down.

SECURITY FOR SIV TRAINING.

You should be in good fitness, not have any medical problems and be able to go in water.

STRONG ADVICE
Stay above the water within the exercise box.
Loss of control - ASSESS ALTITUDE
If your glider is still flying – Keep your direction
- I have control - I open my glider and I fly.
If you are low or in an irrecoverable situation RESERVE or FULL STALL
IF YOU GO IN THE LAKE – stay calm, float on your back. Keep the lines taut between you and the glider by gently moving your arms and wait for rescue.

CONTROL TIPS
Get rid of any wraps on the brake.
In stalls, spins and spirals exit when the glider is in front not when it is behind or it will dive.
If you have lost control - Full stall - count to three – stabilise – let up slowly when wing is in front.
In a spiral exiting with lots of energy turn in the same direction as the spiral.
If you have lost control in a spiral dive you can build up a lot of speed its better to enter the water in a full stall or under a reserve.

If you throw your reserve - immediately B-Line your paraglider evenly.

 

Details of SIV exercises.

 

PITCH CONTROL
To Induce	Pull down brakes evenly and release, build up the pitching motion until glider is diving in front.
To Recover	As glider comes forward pull down the brakes to stop the dive.
Dangers	If you pitch the glider too much it may collapse.
Use of exercise	Good pitch control is essential for flying in turbulent conditions and for recovery from manoeuvres.

 

BIG EARS
To Induce	Put the brakes on your wrists. Reach up the Front risers take the outermost A-lines, pull out and down folding the wingtips in. Pull one side at a time. For Big big ears take 2 A- lines. Weight shift to steer.
To Recover	Let go of the ears and they should recover if not then pump the brakes one side at a time.
Dangers	Glider is smaller with a higher stall point. When coming into land its good to release the big ears early or just land with them. Glider can stall easier if you drop into wind gradient and pump the ears out.
Use of exercise	Increase the descent rate. If you use big ears with speed bar it increases stability and forward speed. Put ears first and then press the speed bar or you may get a front collapse.

 

MINIMUM SPEED
To Induce	Slowly pull down the brakes allowing the wing to lose airspeed. It will get very quite. The glider will look wrinkly, the tips will start to fold back. Glider will enter parachutal stall.
To Recover	Let the hands up smoothly and slowly, glider will surge forward and retake flying speed.
Dangers	Do not release brakes unevenly or glider may enter a spin.
Use of exercise	To know the stall point and speed range of the glider.

 

ASSYMETRIC COLLAPSE
To Induce	Let go of brake on the side you are going to collapse. Reach up to the front riser, grasp it at the maillon and pull down firmly. Back of your hand facing you and twist your hand will give you a stronger grip.
To Recover	Weight shift away from the collapse and maintain your direction line. Use a little brake on the side that is flying. Let go of riser, if necessary pump out the collapse with smooth hard pulls of brake to the collapsed side whilst maintaing course. To practise control turn 360 degree away from collapse
Dangers	Glider may turn to the collapsed side if you don't counter with your weight. You may stall or spin the side that is flying if you apply too much brake. If you feel it turn too fast let up the brake. Don't over re-act.
Use of exercise	Assymetric collapses will happen if you fly in thermic conditions, its important to instill an automatic response to lean away from collapse and keep on your course in case it happens near to hill.

 

SPIRAL DIVE
To Induce	Start 360 turn and build up the speed to enter quickly either wingover slightly or start the turn release it to keep the speed and then put it back on. Build up the bank angle you will be thrown out from the glider. Lots of g-force. When the spiral locks in the leading edge will face the horizon. This is the maximum. More brake and you will enter the S.A.T
To Recover	Weightshift even release the brake slow it a little on both sides. As the glider recovers and climbs, induce one more turn in the same direction this will bleed off the speed and energy and give a safe exit. The glider may take a few revolutions to recover. If it is locked in then your weight is forced onto the inside. Put it evenly.
Dangers	You may lock in. If you enter too quickly you may spin the glider. If you exit the spiral too quickly or by pulling too much on the other side it will have a lot of speed and energy it will climb and then pitch forward a lot. Put a turn in the same direction. Get ready to damp the dive.
Use of exercise	Good way to get down.

 

SPIN
To Induce	minimum speed release one brake pull on the other sense the start of the spin pull when you feel the turn slide release brake. one quarter turn and release then try with a half turn.
To Recover	Hands up If glider is spinning release when it is in front.
Dangers	Twists come from two things. 1st- if you exit bad glider pitches forward to one side collapses but your body is still turning. The side that is open starts to fly in the opposite side and you twist. 2nd - If you stop the spin too quickly then the glider stops but you carry on turning.
Use of exercise	Spin recognition and recovery - if you turn your glider too quickly you may accidently spin.

 

FULL STALL
To Induce	Take two wraps pull brakes down below harness and hold until stabilised
To Recover	when glider is above you and pitching forward release brakes to half way hold and stabilise then release fully and allow to regain flying speed.
Dangers	Releasing too quickly glider will dive too fast and may collapse.
Use of exercise	A good escape if your glider is cravatted or spinning.
