> congratulations Congratulations on the purchase of your new CORAL DHV 1. The CORAL has been designed to offer maximum safety for the entry-level pilot, schools & pilots that demand no compromise in stability.
> warning & liability This manual has been created to give the pilot help and hints to correctly operate this wing. By no means is this a substitute of a training course, nor is this manual intended to give pilot´s knowledge regarding flight safety. Windtech assumes that the purchasing pilot has a license and has taken a training course in order to have enough experience to safely fly the CORAL. This manual cannot be used for operational purposes.
--lines The lines are made of Superaramid kevlar covered with a polyester sheath for protection against wear, UV and abrasion. The lower section of the brake lines is made from Dyneema. This material is less prone to failure after repeated use through the brake pulleys. Karabiners of the risers, also called rapide maillons, are made with stainless steel of 800 Dan.
The CORAL is a DHV 1 accelerated but using the accelerator system close to the ground is not advisable & it should be released as soon as soon as turbulent air is encountered. > flight Each and every glider has a checklist note passed though our strict quality control in the factory. This included line measurement, ground inflation and flight testing. Contact your distributor for more information about this, and if your glider has not been preinflated ask him to do so for you.
may change depending of pilot´s experience, but we remind you that flying in poor weather conditions is the single greatest cause or accidents in free-flying. We recommended that the reverse launch is the best technique when the wind is strong at take off. There are many reverse launch methods/techniques which the pilot can learn. To progress well with your flying, and to be a good pilot, it is necessary to master at least one of the techniques.
flying. With the correct technique & qualified instruction the pilot can learn to help stop collapses by flying “actively” & recover the wing more quickly, by the giving the correct input, when collapses occur. Remember, the glider is tested to recover and so it is always better to under-react than to over-react. Over reacting to a situation can prevent the glider from self-recovering, and recovering air speed, and cause it to enter further unstable situations.
part of the leading edge of the glider, which can sometimes cause a front 'horseshoe' or 'rosette-ing' of the glider, or even a complete 'blow-out' of the whole canopy in extreme situations. When flying, a front tuck may occur while leaving a strong thermal, or more often while using the speed system in turbulent air, or sometimes whilst flying down-wind of another paraglider & being 'waked' by the wing tip vortices of the glider and turbulence wake turbulence of the pilot.
get down safely before it's too late! Always be aware of the weather changing & if in doubt land as quickly as is safely possible. Even though the CORAL is DHV 1 this is not a guarantee against flying in turbulent air. Remember that even an airline jet can crash due to rotors and bad weather! > emmergency procedures techniques & quick descent The following techniques are more advanced & should be practiced ONLY with qualified radio supervision and adequate safety back up.
limit the sink rate of the canopy is approximately 10 m/s and the overload is equal to 2G's. For bank angles higher than 60 degrees the sink rate can achieve 20 m/s but the greater overload (G's) can cause eyesight and equilibrium problems, and cause some people to 'black out' (faint), which consequently can make the manoeuvre extremely dangerous. To recover from a spiral dive, the inner brake must be progressively and slowly released, until the canopy assumes normal flight, and angle of bank, again.
> maintenance Store the paraglider in a dry space away from chemical agents, UV light and high temperature. If the canopy has been packed wet it is necessary to reopen it and let it dry before packing away for a sustained period. Keep the canopy and lines clean, as dirt may penetrate into the fibres and damage them. Clean the paraglider only with fresh water and a soft sponge. If you are unfortunate to land in the sea & survive! Hose/soak the glider with fresh water & dry completely.
