Summary of Contents for PHI Allegro Light

  • Page 1 Manual Version 1.02 of 28.09.2022...
  • Page 2: Technical Description

    Together with the optimized zigzag 3D shaping, a new level of surface quality is achieved. The ALLEGRO light is located in the lower C area with a designed flat aspect ratio of 6. This follows our strategy of realizing small and easily manageable steps between the individual classes.
  • Page 3: Target Group

    Target group The ALLEGRO light is aimed at pilots who fly regularly and who can cope with the higher demands of a C-class device. Several years of flight experience are a prerequisite for being able to control a C-wing in any situation.
  • Page 4 (and other equipment). If the ALLEGRO light is flown in the lower half of the legal weight range, reduced agility can be expected. In strong turbulences a lower stability may be noticeable. The reaction on extreme maneuvers is very relaxed.
  • Page 5: Rapid Descents

    Landing The ALLEGRO light is easy to land. In the final approach against the wind you can flare the wing from a slightly braked position. At about 1m above ground level, the angle of attack should be increased by more and more braking. When the minimum speed is reached, the brakes are pulled to the maximum, the wing then allows a so touch down.
  • Page 6: Asymmetric Collapse

    Then the g-forces increase rapidly and the leading edge will lean towards the ground. In a fully developed deep spiral, the leading edge is almost parallel to the ground. The maximum sink rate with the ALLEGRO light can get up to 25m/s and more.
  • Page 7: Frontal Collapse

    50% of the span affected, the glider shows a more dynamic reaction: Due to the increased drag of the folded wing, the ALLEGRO light will start to turn to the side of the collapse. At the same time, the glider pitches forward as a result of the smaller loaded wing surface and therefore higher wing load and required airspeed.
  • Page 8: Winch Launch

    A er a big collapse or a er a badly executed full stall, a part of the wing might be tangled up in the lines, and wonʼt reopen automatically. This is what you call a cravate. During our extensive test flights with the ALLEGRO light we never experienced a cravate but this situation can not be eliminated with any paraglider.
  • Page 9 In flight, the ALLEGRO light can now be accelerated by pushing the speed bar, which results in a reduction of the angle of attack and as a consequence an increase in airspeed. The speed increase compared to trim speed is about 15 - 17km/h.
  • Page 10: Service And Maintenance

    Attention: If the C handle is pulled down too far, you will stall the wing! The C-Handle is not a substitute for the brake line! This technique is primarily intended to adapt the accelerator travel or to correct the direction when the accelerator is pushed. Service and maintenance General advice With proper and careful handling of the paraglider, it will remain in perfect technical condition for many years even when used...
  • Page 11: Registration, Warranty

    Exceptions are the replacement of lines as well as the repair of small tears (up to 5 cm, which do not affect seams) or holes in the cloth, which can be repaired with the original PHI repair set. A small set of sticking cloth is supplied with the wing.
