Score 0 / 10 0%

When the course of two paragliders crosses at the same altitude, what do they do?

The one coming from the right must give way. The one coming from the left must give way. Both must give way. The one coming from the right must lose height.

On the right is in the right. The one coming from the left gives way.
See the chapter on Rules and regulations

Drag of a paraglider depends on

the air density, shape, surface and speed. the shape and surface of the paraglider, as well as temperature and wind direction. the shape and speed of the paraglider, weight and temperature. shape and weight of a paraglider, as well as temperature and air density.

Drag is not dependent on temperature, nor wind direction.
See the Aerodynamics chapter.

What is the approximate minimum breaking strength of a tow line?

1 N 1 kN 6 N 6 kN

See the chapter on equipment. 1 kN equals a force of 100 kg. The breaking strength should of course not be equal to or below the weight of an average paraglider. Therefore 6 kN or 600 kg is the only feasible answer.

What is the name of the line indicated with G in this illustration?

Main line Top line Brake line Stabilo line

The stabilo line connects to the stabilo panel at the tips of the canopy.

UV-radiation will deteriorate the fabric of the canopy...

...only during flight. ...under all circumstances. ...only after multiple years of use. ...only in clear skies without clouds.

UV-radiation will always damage the fabric.
See the chapter on Equipment.

A pilot weighing 90kg and a pilot weighing 70kg are flying with exactly the same equipment. They are gliding down together from the same take-off at the same time.
Which statement is true?

Both pilots fly for the same amount of time. Both pilots fly the same distance. The lighter pilot has a better glide angle. The heavier pilot has a better glide angle.

The ratio between lift and drag is the same for a heavy or light pilot, all other things being equal. The ratio between forward speed and sink rate is therefore also the same for these two pilots. Their glide ratio is the same and they fly the same distance.
However, both the forward speed and sink rate increase with increasing weight. Therefore the heavier pilot flies faster and goes down faster. Both fly the same distance, but the heavier pilot reaches goal earlier.
See the chapter on Aerodynamics.

There are VFR en IFR flight rules. Which is valid for paragliders?

Paragliders can only fly under IFR. Paragliders can only fly under VFR. Paragliders can fly under both VFR and IFR. Neither VFR nor IFR are applicable to paragliders.

Paragliders do not carry instruments to communicate with air traffic control. Therefore we can only fly under Visual Meteorological Conditions (VMC) and operate under Visual Flight Rules (VFR).

What is katabatic wind?

Wind that is caused by a high pressure area. Wind that is caused by air flowing down a mountain under the influence of gravity. Valley wind. Wind caused by a temperature gradient.

Katabatic wind arises when air cools, for example at night, and flows downslope. Cool air is heavier than warm air.

What is the effect of flying at high altitudes on the descent rate of a paraglider?

The descent rate decreases with altitude. Altitude has no influence on the descent rate. The descent rate increases with altitude. None of the above is true.

At high altitude, the air density is lower. This causes the paraglider to fly faster and descend faster.
See the Aerodynamics chapter.

You have pulled your round reserve at an altitude of around 300m above ground. What do you do next?

Prepare for a rough landing. Pull in the main canopy so it can't open and fly against the reserve. Unbuckle your legstraps and chest strap so you can jump out of the harness just before touchdown. Steer against the wind to ensure a soft landing.

Your descent rate is about 5m/s, so 300m of height will give you about a minute before you hit the ground. That is enough time to pull in the main canopy and after that you prepare for a rough landing possibly with a PLF.
See the section on throwing your reserve in the Advanced flying chapter.
