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.

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.

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.

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 do you do when you can't hear the instructor over the radio during a flight?

You throw your reserve parachute. It is much too dangerous to keep on flying. You keep course to the landing field. Close to the landing field you spread your legs to indicate to the instructor that something is wrong. He or she will then give instructions via signs. Don't forget to keep thinking for yourself as well and make sure you land safely on your feet in open space. You turn around and fly back to the take-off to try and notify the instructor there, so he or she can give directions. You do nothing. The paraglider will touch down sooner or later by itself.

B is correct, A and C are nonsense of course.

Answer D is the second best choice in case your mind goes blank, you panic and you don't know what to do. It's better to do nothing in that case.

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.

What happens when you brake a paraglider so much that the air speed falls below the minimum speed of about 25km/h?

The glider stalls, ie it doesn't fly anymore. The glider will fly on as slow as you want. The glider collapses.

The photo shows what happens when you pull so much brake that the air speed of the paraglider falls below its minimum speed. The glider stalls. Therefore we sometimes call the minimum speed of a paraglider the stall speed.

Don't do this while flying! Unless you are on an SIV- or acrocourse.

Older gliders can also enter a deep stall when you brake too much - see the chapter on Aerodynamics.

What part is indicated by C (the orange line)?

A cell A top line A diagonal rib A stabilo

A diagonal rib connects the upper left corner of a cell with the lower right, or sometimes runs across two or more cells.
This allows the use of fewer lines, reducing the weight and drag of the paraglider.

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.

Standing on launch you see a rain shower approaching. Do you take off?

No, flying in the rain is illegal under air law. Yes, paragliders are not affected by rain and the accompanying wind will dry the paraglider quickly. Yes, if you can be sure that you have landed before the rain shower arrives. No, rain showers are often accompanied by wind gusts, which can be very dangerous for paragliders. Additionally, a wet canopy is more dangerous to fly.

D is the only safe answer. You can never be sure that you have landed before the rain arrives, so C is risky. B is only partly true for light rains, but again you're taking a risk. A is not true, although flying in cloud is illegal in many countries.
