> congratulations Congratulations on the purchase of your new SERAK DHV 1-2. The SERAK has been designed for intermediate and experienced pilots that are looking for a superb all round performing wing with incredibly sweet, dynamic handling , and absolutely minimal compromise in stability.
> warning & liability This manual has been created to give the pilot help and hints to help with the correct operation of this wing. By no means is this a substitute of a training course, or appropriate experience gained with years and hours of airtime, nor is this manual intended to give pilot´s knowledge regarding flight safety.
> certification The SERAK is a paraglider of an intermediate level that has passed easily the tests of the DHV level 1-2. This glider has successfully passed the DHV shock test with a weight equal to the maximum total (all up) take-off weight. This means that the paraglider is certified to resist to a load of 8 (eight) times the gravitational acceleration (8 G´s). As regards the weight range of the glider, ALWAYS be certain that you are within the correct weight range of the glider.
> flight Each and every glider has a checklist note passed though our strict quality control in the factory. This includes line measurement, ground inflation and flight testing. Contact your distributor for more information about this, and if your glider has not been pre-inflated ask them to do so for you. Every glider should be test flow before it is sold. Note that each glider has a unique sticker attached to the centre cell with the serial number, type of glider, size and weight range.
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. If you can achieve 100% control your glider on the ground then you will be a better, safer pilot in the air & this will also help you to understand the dynamics of a paraglider in flight. > thermal flying The SERAK is a pure pleasure to thermal with.
> asymmetrical tuck/collapse An asymmetric tuck / collapse is when part (one side) of the wing ( say 20% or even anything up to 90% of the span) tucks or collapses, usually induced by turbulence but sometimes also though poor pilot control in turns and wing-overs.
> Asymmetric stall (spin) This is a very difficult situation for the pilot to provoke with the SERAK, given it's very low stall speed, you have to really abuse the controls a lot to manage it.
> weather to fly If in doubt about the weather and flying conditions, do not launch! Before going flying you should check the weather forecast & always ask more experienced pilots about the conditions expected for the day. Never fly if there weather conditions are unsuitable, especially with any of the following present or even threatening: Strong wind; Rain; Thunderstorms; Cumuli nimbus; or Cumulus congestus.
shift less hard, to regain level flight. Like this, the pilot can control the bank angle and the sink rate of the glider in the Spiral dive. Always remember that whilst in the Spiral dive you are drifting with the wind, and it is very easy to become disorientated. This manoeuvre is not approved for bank angles higher than 60 degrees. At this upper limit the sink rate of the canopy is approximately 10 m/s and the overload is equal to 2G's.
If necessary, control the surging forward of the canopy by gently braking when the glider is in front of you. Do not brake too hard as you may cause the wing to enter a full stall in this way, and let the brakes back up as soon as the surge has stopped. > 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.
