Why are the cell openings slightly pointed down?
The cell openings are positioned where the air flow hits the profile of the airfoil.
What do we call the risers that are connected to the lines running to the leading edge of the canopy?
These are the A-risers connected to the A-lines.
When is the best time to put your legs down during the landing approach?
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.
It's sunny on launch and you're ready to take off, but the wind has been from the back for quite a while. What do you do?
Gliders suffer the most from direct sunlight. The airtight coating is damaged by the UV-radiation. Don't leave your glider out in the sun unnecessarily.
Additionally, sitting on the reserve parachute may damage it without you noticing, so it might fail if you ever need it. Never sit on your harness.
How tight does the chest strap of the harness need to be?
A short distance beween the karabiners results in a stable flight but enhances the risk of twisting, for example after a collapse.
A large distance between the karabiners results in a higher sensitivity to weight shift but also to more dynamic reactions of the paraglider.
Which data do you need to calculate the wing load?
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.
Which lines carry the most weight?
Most of the weight is carried by the lines attached to the front of the canopy.
'Big ears' are a descent technique and serve to increase your descent rate. Additionally, in which situation is pulling 'big ears' a good idea?
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.
For a paraglider in the mountains, what wind speeds are considered safe to fly?
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.
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.
You can fix a tear smaller than about 5cm (2 inches) yourself. Larger repairs should be done by a professional.
