Then run for a perfect take off In case of light wind you will take off more easily if you slightly pull the brake lines After take off let go brake lines again to reach full flying speed reverse launch This is the method for stronger winds Please note that in strong wind conditions you may need an experienced person to assist and that you can easily lose control in a gust If you feel that the wind is too strong pull one or both brake lines to decrease the pressure on the canopy or pull on the back risers to avoid drag back PRO DESIGN VERSION 1 1 3 05 4 of 10 FLIGHT Basic advice Always fly at safe altitude The THESIS has its best glide ratio with brakes up Minimum sink rate is achieved with brakes slightly pulled In turbulence you can prevent tucks by braking slightly Forward pendulum movements of the canopy can be countered by braking backward pendulum by letting the brakes go FLIGHT WITH SPEED SYSTEM The THESIS Speed System consists of a adjustable 4 riser system b pulleys do not come with the glider they are part of the PRO DESIGN harness C foot stirrup Adjust the Speed System that you reach full acceleration with straight legs Never use the Speed System in turbulent air or near the ground because reduction of the angle of attack decreases the stability of the canopy despite its higher speed ATTENTION At any disturbances of the canopy any kind of tucks the Speed System has to be released imm

8. ediately releasing the stirrup so that the canopy can recover properly The THESIS Speed System accelerates for approx 8 10 km h at full range The system shortens the A risers relative to the B risers which adds speed at the cost of stability Due to the mechanic of the Speed System the A riser reduction is concentrated near full range allowing the pilot to carefully adjust the speed versus stability in this area a lot MAKING TURNS Pull down brake on the side towards which you want to turn To reduce sinkrate also pull outside brake slightly You can also make turns by weight shifting in your harness The looser the chest strap cross braces of your harness the more effective is of your weight shifting BEWARE In extreme situations e g strong and large asymmetric tucks a too loose setting of the chest strap could delay reinflation of the canopy You have best setting if the distance between carabiners is not more than 35cm An optimum technique for making turns is the combination of pulling the brake lines and weight shifting An emergency method for making turns e g damaged brake lines is by either pulling one A riser slightly beware of tucks or pulling on a back riser beware of stall We recommend not to use these methods under normal conditions LANDINGS Whenever possible walk your landing field first to assess hazards and wind Plan for landing with sufficient height That way you avoid stress situations and have ti
9. me to check wind direction and watch other gliders approaching The final approach should always be against the wind and with open brakes to keep the paraglider steerable In case of turbulence you should fly with slightly pulled brakes to avoid tucks To land feet first move to an upright position in your harness in time latest 5 m above ground for the final approach otherwise you could land on your back and get hurt Approx 2 m before touching the ground pull both brakes totally to reduce speed for a soft landing In case of head wind you need not pull the brakes very much for a soft landing top landing especially If there is no wind or wind from the back you have to pull the brakes more strongly ATTENTION If you pull too much on the brakes at an too high altitude your glider could stall and cause you to fall backwards especially with strong head wind In case of strong winds on the ground take wind and pressure out of the canopy by pulling in the brake lines totally or pulling on both back risers Never use the Speed System when landing PRO DESIGN VERSION 1 1 3 05 50f 10 TOW LAUNCHING MOTORIZED FLIGHT The THESIS is suitable for tow launching and flight with rucksack motor Please make sure about the particular law situations in your country ATTENTION The THESIS is not suitable for skydiving 3 CRITICAL FLYING SITUATIONS In this section we describe flying situations which you may cause either intentionally for tr

11. nt paragliding demands caution sense of judgment and theoretical knowledge which you can only acquire and develop in recognized paragliding training programs Paragliding can be a dangerous sport and lead to injury disability or death Do not fly in strong turbulence and winds as these could cause uncontrolled and critical flying situations and lead to crashes If you have any doubts about weather wind or terrain do not launch During production and before delivery we check each paraglider precisely and your dealer test flies it too A note on the technical data label on the glider as well as the filled test flight certificate in this manual confirm this Make sure your canopy was test flown before your first launch otherwise please contact your dealer If you still have any questions when reading this manual call us we ll be pleased to help you We wish you many pleasant flights on your THESIS PRO DESIGN TECHNICAL INFORMATION The THESIS has been developed for self launching but not for tandem flying The THESIS has been tested by the DHV German Hanggliding Association and has successfully passed all load and flight tests The test results confirm that in a broad field of normal and abnormal flying conditions the THESIS proves to be stable and airworthy Please do always consider the fact that in turbulent conditions any paraglider can tuck partly or completely So never fly in these conditions CAUTION The Speed System provides

13. sec recommended and best option You can fully steer with only weight shifting in your harness with loose cross braces There are additional lines mounted to the A risers to easily exercise this maneuver see chapter Big Earing before CAUTION By pulling in the ears too much without using the Speed System there is danger of Deep Stall In case you want to use the Speed System in addition please pull in the ears first and then push the Speed bar Never opposite SPIRAL DIVE Allows fast descent without stalling or collapsing the wing Sinking from 5 to more than 15 m sec Disadvantages The pilot may suffer high G loads and become dizzy The maneuver only allows the pilot to descend vertically with no horizontal movement Altitude is required to enter and exit the maneuver Enter the spiral dive by pulling down one brake line slowly The glider is capable of entering a tight turn without the tendency of stalling the inside wing When doing fast spirals release the inside brake because very little is necessary to maintain the turn It is also recommended to keep the opposite brake pulled slightly to control speed and allow quicker recovery from the spiral Recovery is usually made by slowly releasing the inside brake PRO DESIGN VERSION 1 1 3 05 60f 10 CAUTION The THESIS is a dynamic paraglider and it is very easy to reach high speeds lose altitude quickly and put high physical strains on the pilot Exit the spiral dive with
14. sufficient altitude Attempting fast recovery could cause the pilot to a forward pendulum resulting in a quick climb and stall which could lead to a forward surge of the canopy and a big collapse When descending in a spiral faster than 14 m sec a stable rotation may occur This means that with no brake input the glider will continue to spiral This tendency is strongly dependent on the harness settings tight or loose chest strap and cross brace settings and on the weight shifting If you shift your weight into the turn the glider continues to spiral To stop rotation pull the opposite brake but be careful not to exit too quickly BASIC ADVICE Never exercise the Spiral Dive in low altitudes High sink rate can easily be underestimated B LINE STALL Sinking 5 10 m sec IMPORTANT Stop in time and at appropriate altitude for a total recovery from stall if necessary with active pilot input Not as uncritical as often described See chapter B Riser Stall before 5 MAINTENANCE AND REPAIRS Repairs are best made by PRO DESIGN or an appropriate agent Tears have to be stitched with expertise Sticky back cloth can only fix small tears Keep your paraglider dry and store indoors Protect your paraglider from humidity and sun UV rays lead to loss of strength and damage the fabric Dry a humid or wet paraglider on a shady place in fresh air CAUTION Above all the worst you can harm your glider is to store it humid or wet Humidity
15. y paraglider pilot You should always wear high ankle support boots helmet and gloves Pay attention to warm clothing even in summer it can get very cold at high altitudes In case of extreme atmosphere conditions mid air collision or any material damage a reserve system can safe your life We strongly recommend to fly with a reserve system under all circumstances ATTENTION In case of uncertainty whether you should fly or not never take any risk simply because you fly with a safety system i e do not take off No safety system can guarantee 100 protection under all conditions At worst releasing the safety system can cause entanglement of the lines or other complications possibly both systems could fail by inappropriate interaction 2 FLYING PRECAUTIONS AND CONTROLS PRE FLIGHT CHECKLIST 1 Check the canopy for tears or damage especially the seams where the ribs join the upper and lower wing surface Check the line and brake line connections as well 2 Check the lines for damage especially the condition of the stitching It is important to check the lines and brake lines to clear entanglements The line lengths should be rechecked after every 25 hours of airtime or if anything unusual should occur in the reactions of your THESIS 3 Check the risers and rapid links for perfect condition 4 Check the knots which connect the brake handles with the brake lines They brake lines must not get caught anywhere 5 Check your harnes
