Question 1/10

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.

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.

We lay out the canopy in a semi-circle before take-off. Why?

This reduces the tendency of the lines to tangle. This ensures that the canopy will fill from the middle cells towards the tips. This ensures that the outer cells will fill with air first. This is the only way you can separate the brake lines from the main lines properly.

When the center cells fill first, the canopy will rise steadily and straight.

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.

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.

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.

A paraglider glides down through the air. But at what speed?

The forward speed is over 50 km/h and the sink rate around 10 km/h. The forward speed is over 50 km/h and the sink rate around 1 m/s. The forward speed is around 35-40 km/h and the sink rate around 1 m/s. The forward speed is around 35-40 km/h and the sink rate around 0,1 m/s.

These are all speeds relative to the air!

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.

For a paraglider in the mountains, what wind speeds are considered safe to fly?

Only nil winds from 0 to 1 Bft. Only light winds from 2 to 3 Bft. Only with wind from 0 up to 3 Bft. Only with wind speeds over 3 Bft.

Wind results in turbulence in the mountains. While soaring on a ridge or at low dunes or flying in flatlands may be safe up to 4 Bft or a bit higher using a smaller mini-wing, in the mountains a wind speed up to 3 Bft (a maximum of 20 km/h) is the maximum for most pilots to fly safely. Strong winds are considered 25 km/h or over.

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.
