1. CHARACTERISTICS
1.1 WHO IS IT DESIGNED FOR?
The PEAK 4 is aimed for those experienced pilots with a good level of
flying skills. It has been conceived for cross country and competition,
therefore its capacity to fly kilometer after kilometer with an intensive
pace has been proved. Its strengths are its glide, its excellent rapid
ascent in thermals and its speed when flying. Moreover, it provides to the
pilot a perfect transmission of the air flow and an incomparable security
sensation in its category.
The PEAK 4 is a new glider’s concept. Its design and structure have
changed completely to improve its performance. The PEAK 4 has a new
profile and it has improved the internal pressure of the wing with the
new RAM technology. The lines have been redistributed, new improved
materials and the inclusion of TNT technologies that improves its
performance.
Description of the skills and experience required for this glider:
For those pilots used to recovery techniques, active piloting, to fly on
turbulent conditions and capable of flying these kind of demanding
gliders.
1.2 CERTIFICATION
The PEAK 4 passed the certification according to European EN / LTF
rules. This test was carried out in the Swiss Air-Turquoise laboratories in
Switzerland. All the commercially available sizes passed every required
test with excellent results load test of gand collision test of 1.000 daN
without experiencing any problems.
The certification result achieved on the PEAK 4 for all sizes is:
EN D
LTF D
We recommend paying special attention on the flight test report made
by the certification laboratory, and specially attention to the test pilot
comments (Point 25 on the flight test report).
On the flight test report there is all necessary information to know how
the new glider will react on each maneuver tested.
It is important to take into account that each size can have a different
reaction on the same manoeuvre. Furthermore, the same size on
maximum load o minimum load can experiment a different behavior.
Description of flight characteristics on D class:
Paragliders with very demanding flying characteristics and potentially
violent reactions to turbulence and pilot errors. Recommended for
experienced and regularly flying pilots.
The intervention of the pilot is needed to recover a normal flight state.

1.3 IN-FLIGHT BEHAVIOR
Designing a new high-featured and accessible glider is the result of
years of research and extensive testing flights under all conditions and in
different places in order to provide an easy piloting wing.
The PEAK 4 cells are impregnated with Niviuk technology: equipped with
SLE, STE, TNT, DRS and RAM air intake technology in the leading edge
to gain performance, speed and stability. The parasitic drag is reduced to
the minimum decreasing the overall length of the suspension lines thanks
to its internal architecture. It offer you more features and more safety with
less aspect ratio and weight.
