Pilot’s manual for BiGolden4 4
4. ADJUSTING YOUR GLIDER
Before it reaches the customer every BiGolden4, goes through a final check and test-flight to verify that its
characteristics and measurements correspond to the manufacturer's specifications. You may only make adjustments
to brake-line lengths of your BiGolden4 – and only then in keeping with the recommendations of this manual.
Other adjustments or changes to your BiGolden4 lead to a loss of guarantee, airworthiness and validity of the
certification. Do not endanger yourself and other pilots by amateur modification. If you have any suggestions for
improvements let us know and our test-pilots will try out your ideas.
4.1. Brake line adjustment
The BiGolden4 risers have adjustable positions for the guide pulleys for the
main control lines to suit each pilot’s physical build, harness hang-points, and
style of flying. Standard pulleys are placed in the top position, which fits most
cases – see picture.
CAUTION: If you change the position of the guide pulley then it is necessary to
change the position of the brake handle by about the same length as the
distance between the loops for the hanging guide pulleys.
When you receive your new BiGolden4 the main brake lines are adjusted to
the length set during the certification test. This length should suit most pilots
and is indicated on the main control line (R0.0). It is of course possible to adjust
the brake-line length to suit each pilot's physical build, height of harness hang
points, or style of flying. We recommend that you act wisely when adjusting
brake-line length and change the length in small, successive steps.
If you need to adjust brakes back to the basic position and the marks on the
main brake lines are vague, use the following lengths for relevant size (length
is valid for upper position of brake guide pulley):
BiGolden4 37: 303cm
BiGolden4 42: 322cm
Brake lines that are too short may:
Lead to fatigue from flying with your hands in an unnatural
position.
Impede recovery from certain unstable manoeuvres.
Certainly reduce speed range of your glider.
Brake lines that are too long may:
Hamper pilot’s control during launch.
Reduce control in extreme flying situations.
Make it difficult to execute a good flare while landing.
Each brake line should be tied securely to its control handle. Use knots which will guarantee this, for example,
Double Dragon.
5. OPERATION IN FLIGHT
This manual is intended as a guide to the characteristic features of your new BiGolden4 paraglider. Under no
circumstances should it be used as a ‘learn-to-fly’ manual for paragliding or as a substitute for a paragliding
training course.
5.1. Standard flight
5.1.1. Pre-flight check
Pre-flight check is essential part of getting ready to fly and that's why you should pay special attention to it. Check
the canopy and the lines for damage, clear the lines of any tangles, check the riser maillons, trimmers and don’t
forget to check your harness and your reserve parachute.
Before launch spread the canopy out into a slight arc and check that:
all cell openings are free
no lines are looped around or under the canopy
no lines are tangled or have a knot in them
any twigs, grass or other objects are not entangled in the lines or in the canopy
the risers are not twisted
