There are VFR en IFR flight rules. Which is valid for 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).
Which lines have the following properties:
sensitive to bending, heat resistant, yellowish colour?
Kevlar is a trade name for aramid. You can recognize it from its brownish or yellow color.
What is katabatic wind?
Katabatic wind arises when air cools, for example at night, and flows downslope. Cool air is heavier than warm air.
Take a look at the landing circuit above. What is meant by 1?
Flying an U-circuit or constant aspect approach for landing starts at the position indicated by 1 by losing height. You fly circles until you have reached the right height to start the rest of the landing circuit.
What is the relationship between lift, drag and glide ratio?
The Lift over Drag or L/D ratio is the same as the ratio between forward speed and sink rate, which gives you the glide ratio.
Which line material has the following properties:
sensitive to heat and moisture causing stretching and shrinking, white color.
Dyneema is a trade name for polyethylene fiber.
What is the purpose and meaning of the acronym IMSAFE?
IMSAFE is used throughout aviation to assess your fitness to pilot an aircraft.
The acronym is: Illness, Medication, Stress, Alcohol, Fatigue and Emotion.

What is the name of the line indicated with G in this illustration?
The stabilo line connects to the stabilo panel at the tips of the canopy.
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?
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.
Your wing collapses on the right hand side. What is the first thing you do?
Most collapses will reinflate spontaneously. Therefore it is most important to keep your course by weightshifting and applying a bit of brake if necessary and avoid obstacles or other pilots. Then look up and see if you need to solve the collapse.
See the section on Incidents in flight in the chapter on Advanced flying.
