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 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 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.

You just landed. What do you do?

You bundle up the glider in a 'field pack' and take the shortest way to the designated packing area. You bundle up the glider in a 'field pack' and take the shortest way to the edge of the field and from there to the designated packing area. You report to the instructor. When he or she says it's ok, you bundle up the glider in a 'field pack' and walk to the designated packing area. You pack up your vulnarable glider on the spot and then you report to the instructor.

Directly after landing, look around for other gliders that are about to land and clear the landing area as quickly as possible, without disturbing others.

What happens when you fly too slowly?

The wing collapses. The glider will enter a deep stall. Nothing, you can fly as slow as you want.

Below the minimum speed or stall speed, the wing stops flying and will descend straight down like a parachute. This is a very unstable situation and often leads to a spin or stall.
See the chapters on Aerodynamics (stalls) and Advanced flying.

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.
See the section on Launching in the Basic techniques chapter.

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.

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.

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 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.
