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.

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.

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.

How tight do you need to pull the leg straps of the harness?

As tight as possible so you won't fall out of the harness and you won't move from side to side in a turn. As loose as they will go so you can easily accelerate during take-off and the circulation in your legs is not hindered. That doesn't matter, as long as the buckles are secure. They need to be loose enough that your flat hand can just fit between the straps and your legs. That way your movements aren't hindered too much and you can still get into the harness easily after take-off.

The tightness of the leg straps does not influence the flying properties of the paraglider.

When the leg straps are too loose, after take-off you will find yourself hanging low under the seat and it's more difficult to get in the harness.

Too tight will hinder your movements during take-off, depending on the harness design. In some harnesses it will prevent you from getting into the seat fully.

'Big ears' are a descent technique and serve to increase your descent rate. Additionally, in which situation is pulling 'big ears' a good idea?

When trying to fly into a strong headwind. When flying in turbulent conditions. When turning in a small thermal. All of the above are correct.

Pulling big ears reduces the wing area and therefore increases the wing load. This stabilizes the canopy somewhat. It also increases the flying speed but in most cases this is counteracted by the extra drag the ears create.

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 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.

During daily inspections you notice a tear of about 2.5cm or one inch in the canopy of your paraglider. What do you do?
1. You fix the tear with ripstop tape on both sides of the fabric.
2. You take the glider to a dealer or manufacturer to have it professionally repaired.

1 is correct. 2 is correct. Neither 1 nor 2 are correct. 1. is a temporary solution, go for 2. as soon as possible.

You can fix a tear smaller than about 5cm (2 inches) yourself. Larger repairs should be done by a professional.
See the chapter on Equipment.

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.

Which data do you need to calculate the wing load?

The weight of the wing, the flat surface of the wing and the weight of the harness. The take-off weight and the flat surface of the wing. The span, the flat surface and the weight of the wing. The aspect ratio and the take-off weight.

The wing load is defined as the weight on the wing per square metre. Therefore you need the total take-off weight and the flat surface of the wing to calculate it. For example, a 25m² glider flown by a pilot with a TOW of 100kg has a wing load of 4kg/m².
