Control of cap strength:
• The cap strength test is carried out using the Bettsometer (B.M.A.A.aproved patent No. GB 2270768 Clive
Betts Sales). In this test is in the top and bottom sail in the area of A-lines
bumped a needle-thick hole and tested the cloth for its tear propagation resistance.
The limit of the measurement is set at 800 g and a crack length of 5 mm.
• The exact test procedure is specified by the operating instructions of the bedometer. The determined
measurement value is entered in the verification log.
Control of the air permeability of the cloth:
• Using a JDC textile watch, a porosity measurement is made on at least 5 points of the top sail
(with at least 2 measurement points in the middle third of the screen) and at least 3 points of the
Untersegels performed. The determined values are documented in the verification report. The measuring
Points on the upper / lower sail are distributed over the span about 20-30 cm behind the inflow edge.
• Limit values: no measuring point may reach a value of less than 10 seconds. Returns a measurement
a value less than 10 seconds, the paraglider loses its operability.
Control of trim and adjustment:
• All lines are to be checked according to the linen overview plan, if they were also properly lulled, and that
also all linen levels are free. Likewise, the brake lines are to check that everything is properly tucked in
and is free.
• The visual inspection must correspond exactly to the linen overview plan.
Check flight:
• Check flights are only required for major repairs.
• During check flight it must be determined if the flight characteristics of the structure to be checked
have changed compared to a brand new device.
• The examiner must be able by his flying skills and experience to be able to comply with the building
regulations to compare the flight behavior of the structure to be checked and possibly changed properties
determine. This includes above all things:
• that the pattern and its characteristics / flight behavior are known to the examiner.
• Also, the building codes in force at the time of approval of the design
be known.
• A check flight must have at least the points Winding up, Tipping, Ten
to negative curves, control path lengths,> 50% unilateral folding.
• If the device under test does not behave properly in any way, you may use this device
Device can no longer be flown and must be checked by the manufacturer. under no circumstances
You may try to fix the error yourself.
Other scheduled examinations:
• control of the linen stretch:
All innermost leashes should first be measured under a load of 6 daN and then for 5 sec.
to charge customers with 20 daN and then again under 6 daN to measure. This activity is
conditionally before the measurement of the line lengths and the elongation values in the
verification protocol hold.
