What do we call the risers that are connected to the lines running to the leading edge of the canopy?

A-risers B-risers C-risers D-risers

These are the A-risers connected to the A-lines.

What is the weight of the fabric used to make paraglider canopies? (g/m²)?

500g/m² 350g/m² 35g/m² 10g/m²

Very light fabric strong enough for paragliders can be as light as 25g/m². Very strong and heavy fabric weighs 40g/m² or more.
At around 35g/m², you can calculate that the weight of the fabric of just the top and bottom sail of a 25m² canopy is a bit less than two kilos.

Which lines carry the most weight?

The rear lines (C or D-lines) The middle lines (B or B and C-lines) The lines on the front (A-lines or A and B-lines) The brake lines.

Most of the weight is carried by the lines attached to the front of the canopy.

You're on a straight course and you don't need to change direction any time soon. What do you do with the brake handles?

Let go, because holding them all the time is unnecessary and tiring. Hold them at all times, because the wing will shoot in all directions if you let go. Hold the handles lightly and relax your arms. This ensures a bit of pressure on the brake lines. Hold the handles and pull them down quite a bit. The wing will fly slower and more stable that way.

Modern paragliders fly best without any brake applied - at the so-called trim speed.

But by applying a little bit of pressure, you take out the slack in the brake lines. You feel better what the wing is doing and you can react quickly and subtly to keep the wing straight overhead. This is called active flying.

If you have some more experience it doesn't hurt to let go of the brake handles and relax, but only if it's safe to do so.

How tight does the chest strap of the harness need to be?

As tight as possible, so you can't fall out of the harness and you will be stable in your harness in a turn. There needs to be 42-46 cm between the karabiners, about the length of your arm from elbow to fist. Most paragliders are designed and tested with the chest strap of the harness at that width. It doesn't matter, as long as the buckles are secure. It doesn't matter. The chest strap is only needed during take-off, but you may as well leave it open as you are secured in the harness by your leg straps.

A short distance beween the karabiners results in a stable flight but enhances the risk of twisting, for example after a collapse.

A large distance between the karabiners results in a higher sensitivity to weight shift but also to more dynamic reactions of the paraglider.

A pre-flight check should be executed...

...before take-off. ...after every flight. ...every six months or as often as the manufacturer recommends. ...only by your instructor.

Before you take off, you should check at least these things: pilot, lines, canopy, wind, airspace.

What are the minimum requirements for a safe take-off?

The possibility to safely abort the launch. A light wind from the front. Clear of cables in a 500m radius. A, B en C are correct.

A straight headwind is not necessary, you can take off in a slight crosswind. The runway should be clear of cables and other obstacles, but a 500m radius is not necessary. It is however essential to be able to abort your launch, for example when you notice a knot in the lines.

Why are the cell openings slightly pointed down?

To increase the aerodynamic properties of the paraglider. Because the airflow is coming from the front and below at an angle. To enable dirt or dust to fall out easily. To achieve a venturi effect.

The cell openings are positioned where the air flow hits the profile of the airfoil.

When is the best time to put your legs down during the landing approach?

As soon as you can see the landing field. After you have burned off excessive height and start your landing circuit. At the last moment during the landing flare. When you are on the final leg of the landing circuit.

D is the safest option. The others are either uncomfortable and unwanted because you can't use weightshift anymore, or unsafe if you are too late and land on your bum risking a back injury.

Which pre-launch check is the most important?

Checking the lines and canopy are laid out cleanly. Checking your flight instruments. Checking your leg straps are fastened. Checking if there is sufficient thermal activity.

Even though all newer harnesses have a safety feature to prevent you from falling out of the harness if you forget your leg straps, this is very uncomfortable and on an older harness it may be a fatal mistake. Checking lines and canopy is of course very important as well.
