Para todos os curiosos, pilotos e interessados em geral, queria fornecer de uma forma muito simples de entender com videos explicativos, como são testados todos os Parapente construidos por fábricas certificadas um pouco por todo o mundo.
Para os que já sabiam ficam a conhecer um pouco mais em detalhe o processo, para todos os outros serve para assegurar ainda mais a credibilidade e segurança com que são feitos e desenvolvidos os nossos Parapentes, desta feita ficam a perceber que de acordo com 24 testes aplicados rigorosamente por um piloto de testes qualificado a cada asa que os fabricantes apresentam para certificação, e de acordo com o resultado obtido na prática, em voo, é dada a classificação às asas em concordância com a sua segurança.
Nestes testes o que importa para a empresa certificadora é apenas a segurança das asas em questão de forma a atribuir uma classificação que simplifica e assegura o processo de escolha por parte das escolas e de pilotos por todo o mundo.
Esta classificação vai desde a asa de escola até competição, por ordem da mais segura para a mais exigente a nível de pilotagem:
EN A - (antiga DHV 1)
EN B - (antiga DHV 1-2)
EN C - (antiga DHV 2)
EN D - (antiga DHV 2-3)
Transcrevi os testes para aqui de forma a que se algum dia o retirarem do site, continua disponível:
Reception: We receive a new glider from Manufacturer. We make sure we have the right size and weight range. Manufacturer shall mark the glider and the brake lines before send it to us If not, we must mark the glider 50% and 75% of the span and 30 % of the cord. These marks help us to make the correct asymmetric and front collapses. We mark also the brake range; 0 point, stall point and afterwards 25%, 50%, 75% of the brake range. We must also receive all technical files regarding the glider.
Flight test; EN926-2:The test pilot is ready for testing the glider in free-flight. The following manoeuvres need to be done:
1. Inflation/Take-off video
2. Landing video
3. Speed in straight flight video
4. Control movement video
5. Pitch stability exiting accelerated flight video
6. Pitch stability operating controls during accelerated flight video
7. Roll stability and damping video
8. Stability in gentle spirals video
9. Behaviour in a steeply banked turn video
10. Symmetric front collapse video
11. Exiting deep stall (parachutal stall) video
12. High angle of attack recovery video
13. Recovery from a developed full stall video
14. Asymmetric collapse video
15. Directional control with a maintained asymmetric collapse video
16. Trim speed spin tendency video
17. Low speed spin tendency video
18. Recovery from a developed spin video
19. B-line stall video
20. Big ears video
21. Big ears in accelerated flight video
22. Behaviour exiting a steep spiral video
23. Alternative means of directional control video
24. Any other flight procedure and/or configuration described in the users manual video

Each manoeuvre is done at least two times by the test pilot, to make sure to find the same and correct behaviour of the glider. The manoeuvres shall be done in certain angle in front of the camera. This is done for minimum and maximum weight procedure. In average we need three flight per procedure. The manoeuvres is documented by video and voice comments from test pilot during the flight.
Results:After flight test the pilot write the flight test report. If test pilot is not sure about the result, we have to check the video of the recorded flight. If we still not sure about the result, we have to re-begin the flight and maybe with different camera angle.
Control the glider: The glider is checked and lines are measured if it is corresponding to the user manual. video
Load test EN926-1: The glider also need to go through sustained load test, shock test and bending test for the line.
Shock test: Carry out the test using a weak link to limit the loads to a maximum force
Sustained loading test: The paraglider is attached to a test vehicle and flown whilst loads are measured. Load diagram you will find on this page under “all reports”.
Bending test: The lines goes through 5000 bendings before we broke the line. We measure the load when the line is broken. Then we do a calculation for strenght of the lines.
video
Final: We give the glider a certification number, editing the video, writing and publish reports. The video is manufacturers property and we can not publish it.
Here you can see an explanation of FLIGHT TEST REPORT and STICKER.
Agora já sabem como tudo é feito ;)
