ALPHA 4 - Time to fly!

The ALPHA 4 is ideal for trainee pilots and pilots who want the maximum in passive safety. Easy take-off behaviour, direct and agile handling as well as light control pressure are the hallmarks of this DHV 1 rated paraglider. The performance is suitable for cross-country flights and extended fun in the thermals, even for less frequent flyers.

Behaviour

• Easy and homogeneous inflation : the wing rises progressively, without hard point and does not overtake the pilot. Easy to correct when not inflating symetrically. It is obvious for an advanced pilot but also for beginners.
• Progressive and homogeneous spiral braking : perfect speed and amplitude reaction. When releasing the brake, the wing comes by itself above the pilot's head without any oscillating motion.
• High level of performance in its category and great fun. Best glide angle at trim speed, soft speed system at the beginning and efficient on the whole speed range

Innovations

Design features:

• Reinforced leading edge, with Mylar : better rigidity and stability of the wing.
• Each cell receives a line, to maintain a perfect profile.
• The cell width is scaled, it gets smaller as you go from the centre to the wing tip (the last four being closed off) giving a beautifully clean aerodynamic shape.
• 4 risers: easy to handle - for beginners as well as for advanced pilots - and giving better speed system.
• Compression straps sewn between the attachment points of the lines : the distance between the cell walls always remains the same, in order to maintain the profile and keep the shape of the wing i.e. better performance in the turn.

Construction details:

• All of the sewing and stitching is internal.
• The leading and trailing edges are reinforced with a Mylar border to increase rigidity and also to make them less sensitive to the high tension to which they are subjected.
• The winglets on the wing tips are aerodynamic elements but ADVANCE signature also, diminish the wing tip turbulence (vortex effect) and give much more precision in the turns.
• The lines remain in correct position on their small quick links thanks to a plastic clip.
• The braking is optimised by utilising a system with rings creating braking action on the wing tip first.
• The brake handles are reinforced in a way that makes them easy to take and comfortable. They are attached to the risers with a magnetic snaplock.
• The wing tips receive a Velcro, easy to open to remove the twigs and gravels that could have entered the glider.
• The big ears kit is easy to use and perfectly integrated to the risers.
• The brake handles receive a swivel, that avoids the main brake line twisting when making a wrap around the hand.
  Certification
  Our R & D Team considers the certification tests from the start of the development process. But to be fully satisfied with the wing - behaviour, pleasure, performance - remains our first priority.
• All sizes of the ALPHA 4 are certified according to DHV 1 requirements, with the speed system
