The term "angle of attack" represents the angle between the chord of the profile and the relative wind. This means that it measures the angle at which the oncoming air hits the wing or airfoil. The angle of attack is an important factor in determining the lift and drag forces acting on the aircraft. A higher angle of attack can generate more lift but also more drag, while a lower angle of attack can reduce lift and drag. Therefore, understanding and controlling the angle of attack is crucial for aircraft performance and stability.

When a pilot has consumed substances like alcohol or drugs, their ability to assess situations and make judgments will be impaired. This is because drugs and alcohol can affect cognitive functions, such as decision-making and problem-solving skills. Therefore, the pilot's ability to evaluate the situation and make appropriate decisions during flight will be reduced.

You can repair a tear under 10cm on the glider by using fabric and glue.

The correct answer is to cancel the flight because if one of the bottom B-lines of the glider is torn, it can compromise the safety and stability of the flight. It is important to ensure that all the lines are intact and in good condition before taking off to prevent any accidents or incidents during the flight.

The correct answer suggests that the best helmet to wear for paragliding is one that has EN966 certification because it is a specific certification for paragliding. This certification ensures that the helmet meets the necessary safety standards and requirements for paragliding activities.

The correct answer states that harnesses with ram-air type airbags fold smaller in the rucksack, providing better protection for pilots during high impact falls. This means that the impact forces are distributed directly onto the protection, minimizing the risk of injury.

The correct answer is "As part of your pre flight check before each and every flight." This means that you should check if your reserve pin and handle are secure before every flight as a part of your pre-flight routine. This is important for ensuring the safety and functionality of your equipment.

Before taking off, the last thing you must check is whether your airspace is clear. This is important to ensure the safety of your flight and to avoid any collisions or obstacles in your path. Checking that your airspace is clear means ensuring that there are no other paragliders, aircraft, or objects in front of you that could pose a risk during takeoff. By doing so, you can minimize the chances of accidents and ensure a smooth and safe flight.

The correct answer is the statement "According to APPI regulations, the use of drugs or alcohol before or during flight activities is forbidden." This statement accurately reflects the regulations set by APPI regarding the use of drugs or alcohol during flight activities. It implies that APPI does not allow the consumption of alcohol or drugs before or during a flight.

The correct order for the 6 point check on take off is as follows: 1. Buckles fastened, 2. Equipment: glider & lines, speed system, reserve pin, 3. Stop line, 4. Airflow, wind & weather, 5. Free Air space, 6. Enjoy (mental state).

The correct answer suggests that when a paraglider comes into contact with sea water, it should be rinsed thoroughly with clean water as soon as possible to remove the salt. After rinsing, it should be dried in the shade to prevent further damage. This is because saltwater can be corrosive and can cause damage to the fabric and materials of the paraglider if not removed promptly. Drying in the shade helps to prevent fading or damage from direct sunlight.

The correct answer states that all of the above points are correct. This means that all of the mentioned points - checking for damage, wear level, and overall condition of the equipment, ensuring compliance with connection and preparation instructions, and identifying and fixing equipment problems before takeoff - are necessary steps to ensure the safety of the flight.

The term "angle of attack" represents the angle between the chord of the profile and the relative wind.

The attitude of the pilot is the most important factor in ensuring the safety of the flight. A pilot's attitude refers to their mindset, behavior, and approach towards their job. A positive and responsible attitude is crucial for making good decisions, following safety procedures, and effectively managing any potential risks or emergencies that may arise during the flight. A pilot with a good attitude will prioritize safety, stay calm under pressure, communicate effectively, and continuously strive to improve their skills and knowledge.

If you pull down one control toggle deep while releasing the other up quickly, it creates an imbalance in the wing's lift and can cause one side of the paraglider to stall. This stall can lead to an asymmetric collapse, where one side of the wing collapses and the paraglider enters a spin. This is a dangerous situation that can result in loss of control and potential accidents.
