6. rib reinforced The changes in the internal structure mean higher passive safety The canopy is reinforced by tapes which connect attachment points inside the cells this prevents distortion and helps the canopy keep its form A new line system helps to reduce the length of the main lines The brake attachments have been moved to the trailing edge to create more precise handling and feedback All the stitching is on the inside of the canopy for greater protection Testing and certification The Vega 111 has passed certification EN C The certification of each canopy and its serial number is found the wingtip label Certification 1 valid for all harnesses of ABS type This type of harness allows a certain degree of adjustment to be made to the length of the waist strap The recommended distance between the carabiners is 42cm In common with all other paragliders when cross bracing is looser than the recommended 42cm weight shift control increases and the glider feels more sensitive However automatic recovery from a collapse when using slack cross bracing can be slower and more unpredictable When cross bracing is tighter the pilot feels more stable but the effectiveness of weight shift is less effective The Vega 4 has been designed for hill and or tow launches It is not a paramotor wing The use of a power unit paramotor or motor with the Vega 4 has not been tested by the manufacturer or by the testing authority Vega 4
7. steadily using forward or reverse launch techniques There is no tendency to overshoot the pilot To forward alpine launch in light or nil wind there is no need to pull the risers hard Allow the glider to stabilise overhead and run positively forward checking the canopy is fully inflated and clear of any knots or tangles Reverse launching 1 recommended in strong wind Flight The best glide speed in calm air is achieved in the hands up position The best sink rate is produced with both brake lines drawn down equally to about 20 of their range Turning The handling characteristics of the Vega 4 require no special or non standard procedures Brake pressure is progressive This gives a responsive and sporty feel to the handling In an emergency e g a broken brake line the Vega III can be manoeuvred by steering carefully with the rear risers or by weight shift Using the speed system The speed system on the Vega 4 comes supplied with Brummel hooks ready to attach to your own speedbar of choice When you have done this check the speed system runs smoothly by hanging in your harness before flying In particular check that the speed system won t be engaged when in normal flight Unnecessary knots and loops in a speed system are not recommended Vega 4 5 Maximum useable speed is of the strong points of Axis paragliders and the Vega 4 is no exception However in spite of this exceptional stability any collapse at f

9. you want to extend the life of the glider It is important these manoeuvres are initially practiced under qualified supervision and preferably during a safety training course Big ears Vega 4 C RKiIS This is the easiest and safest technique for descent while maintaining forward speed Depending on how much of the wing tip you deflate 3m s to 6m s sink rate can be achieved While in big ears your forward speed can be increased by using the speed system The Vega 4 can be steered with big ears in by weight shift alone Initiation Reach up as high as possible and take hold of the outer A line on each side of the glider Pull one in first maintain direction and then pull in the second Hold them in firmly Make sure the lines are pulled down equally on each side and your big ears are even Recovery Under normal circumstances the ears will come out on their own when the lines are released Opening may be accelerated by slightly pumping the brakes B line stall This is an effective way of making a rapid descent but doesn t allow any forward speed Initiation Take hold of the B risers just below the maillons and smoothly pull them down twisting your hands until the canopy shows a span wise crease at the B line attachment points It is difficult to pull at first but becomes easier as the aerofoil creases Your sink rate will increase while your forward speed will reduce to practically zero Don t release the lines immed
10. ctive flying will help avoid deflations The aim is to keep the glider above your head in all situations by responding correctly to the glider s movements by using the brakes and weight shift It is important these manoeuvres are initially practiced under qualified supervision and preferably during a safety training course Asymmetric collapse The Vega 4 will normally re inflate after an asymmetric collapse without input from the pilot but the wing will turn towards the collapsed side You should always maintain course and direction by weight shifting away from the collapsed side This can be reinforced by applying a small amount of brake on the opposite side to the deflation If the collapse stays in the collapsed side can be re inflated by pumping the brake on the collapsed side in a firm and smooth manner If you experience a big collapse while accelerated the canopy will fall behind you due to the difference in inertia between you and the canopy You must wait until you pendulum back under the canopy before dealing with the deflation Reacting too early can risk stalling the glider completely Release the speed bar immediately if you have a big collapse during accelerated flight and while keeping weightshift neutral apply slight brake to the open side Let the glider enter a turn if space allows in order to avoid a spin or stall Symmetric collapse A symmetric or frontal collapse will normally reopen without any pilot input The Vega 4
11. d have made a test inflation and test flight before delivery to you Brake line length When you receive your new Vega 4 the brake line length is set the same as the Axis test glider This length has been finely tuned by Axis test pilots and it should not be necessary to adjust it If you feel it is necessary to adjust the brake line length to suit physical build height of harness hang points or style of flying we recommend you test fly the glider after every 20mm of adjustment There should always be free brake travel when the glider is flown hands up This means when you look at your brake lines in flight with your hands up there should be a slight bow or arc to the line the brake lines should not be tight This is to prevent the brakes being applied when the speed system is used Brake lines that are too short e lead to fatigue from flying with your hands an unnatural position e May impede recovery from certain manoeuvres e Will certainly reduce your glider s speed range Brake lines that are too long will e Reduce pilot control during launch e Reduce control in extreme flying situations e Make it difficult to execute a good flare when landing Each break line should be tied securely to its control handle with a suitable knot Other adjustments or changes to your Vega 4 lead to a loss of guarantee airworthiness and validity of EN certification and may endanger both yourself and others If you have any sugges

13. iately the glider should be left to settle before releasing Recovery Let go of the risers smoothly but determinedly and symmetrically The Vega automatically returns to normal flight without any deep stall tendencies but may dive slightly forward If the risers are released slowly and very unevenly the glider could start to spin Spiral dive The spiral dive is the most effective way of making a fast descent During the spiral dive the pilot and glider will experience strong centrifugal forces which strain the glider As such it should be considered an extreme manoeuvre Initiation Weight shift and smoothly pull on one brake so the glider goes from a normal 360 degree turn into a steep turn and from there into a spiral dive Once established in the spiral the descent rate and bank angle can be controlled with weight shift and the outer brake Recovery The Vega 4 recovers from a spiral spontaneously as soon as the brakes are released and weight shift returns to neutral To exit allow the spiral to slow for a turn or two by applying outer brake and weight shift then release smoothly Always finish a spiral dive at a safe altitude Vega 4 5 Flying turbulent conditions Deflations can occur when flying in turbulence but in most situations the Vega 4 will stabilise without pilot input Flying with a little brake applied equally will help to prevent deflations and allow you to experience more direct feedback A
