A paraglider stall is a potentially dangerous situation where the airflow over the wing becomes disrupted, causing a loss of lift and a rapid descent. Understanding the causes, how to recognize the signs, and knowing the correct recovery techniques are crucial for any paragliding pilot. This knowledge enhances safety and allows pilots to react effectively in emergency situations. Learning about stalls and practicing stall recovery maneuvers under the supervision of a certified instructor is a fundamental part of paragliding training. A well-prepared pilot can minimize the risk associated with stalls and enjoy safer and more confident flights.
What is a Paraglider Stall?
A paraglider stall occurs when the angle of attack (the angle between the wing and the oncoming airflow) becomes too high. This causes the airflow to separate from the wing surface, resulting in a loss of lift and a sudden drop in altitude. Essentially, the wing stops ‘flying’ and starts ‘falling’.
Causes of Paraglider Stalls
Several factors can contribute to a paraglider stall. Understanding these factors helps pilots to avoid situations that could lead to a stall.
- Aggressive Control Inputs: Pulling the brakes down too far, too quickly, or asymmetrically.
- Slow Airspeed: Flying too slowly, especially in turbulent conditions.
- Turbulence: Strong gusts or rotor can disrupt airflow over the wing.
- Pilot Error: Misjudging airspeed, improper brake input, or lack of awareness.
- Wing Condition: Old or damaged wings may be more prone to stalling;
Recognizing the Signs of an Impending Stall
Early recognition of a potential stall is key to preventing it. Pilots should be aware of the following warning signs:
- Soft Brakes: Brakes that feel less responsive than usual.
- Reduced Airspeed: A noticeable decrease in airspeed.
- Mushy Feeling: A loss of pressure and a vague feeling in the glider.
- Wing Rocking: Unstable or erratic wing movements.
Paraglider Stall Recovery Techniques
If a stall occurs, quick and decisive action is required. Here’s a breakdown of the recovery procedure:
- Release the Brakes: Immediately release the brakes fully or slightly, allowing the wing to regain airspeed.
- Weight Shift: Shift your weight forward to further encourage the wing to re-inflate.
- Check Airspeed: Monitor your airspeed and make sure it’s within the safe operating range.
- Controlled Braking: Once the wing is flying normally, apply the brakes gently to control your descent and regain directional control.
Table: Comparing Different Stall Types
Stall Type | Description | Cause | Recovery |
---|---|---|---|
Full Stall | Complete loss of lift, wing folds back. | Excessive brake input, very slow airspeed. | Release brakes immediately, weight shift forward. |
Spin | One side of the wing is stalled, causing a rapid rotation. | Asymmetric brake input, often combined with slow airspeed. | Release brake on the stalled side, weight shift to the flying side. |
Parachutal Stall | The wing descends vertically like a parachute, with little forward movement. | Deep brake input held for too long. | Release brakes fully and quickly. |
FAQ About Paraglider Stalls
Q: How can I prevent a paraglider stall?
A: Maintain adequate airspeed, avoid aggressive brake inputs, and be aware of wind conditions. Practice active flying techniques to keep the wing inflated and stable.
Q: Is it dangerous to practice stall recovery?
A: Practicing stall recovery should only be done under the supervision of a qualified instructor in a safe environment. This allows you to learn the correct techniques and build the necessary muscle memory to react effectively in a real-life situation.
Q: What should I do if I can’t recover from a stall?
A: If you are unable to recover from a stall, deploy your reserve parachute immediately. Your reserve parachute is your last line of defense in an emergency situation.
Q: What is the role of the instructor in stall practice?
A: The instructor plays a vital role. They guide you through the correct procedures, provide feedback, and ensure your safety throughout the training process; They can also assess your progress and tailor the training to your individual needs.

My Personal Experience with Stalls
I remember the first time I intentionally stalled a paraglider during my advanced training with my instructor, Jean-Pierre. It was both terrifying and incredibly valuable. We were high above the designated training area, and the air was relatively calm, perfect for practicing these maneuvers. Jean-Pierre calmly walked me through the process, emphasizing the importance of recognizing the subtle signs before the full stall occurred.
Initial Hesitation and Gradual Brake Input
Honestly, I was apprehensive. The thought of intentionally making the wing collapse felt counterintuitive, especially after spending so much time learning how to keep it inflated. But Jean-Pierre assured me that with proper technique and quick reflexes, it was a safe and controlled exercise. I started by gently pulling the brakes down, feeling for that “mushy” feeling he described. It’s hard to explain, but it’s like the brakes lose their crispness, and the wing feels less responsive.
The Stall and the Recovery
As I pulled the brakes further, the airspeed dropped noticeably. Suddenly, whoosh, the wing bucked, and I felt that unmistakable sensation of the air leaving the canopy. It wasn’t a violent collapse, but more of a controlled deflation. My stomach dropped for a split second, but I immediately remembered Jean-Pierre’s instructions: release the brakes! I snapped my hands up, shifting my weight forward slightly. I felt the wing begin to reinflate almost immediately. The feeling of the wing refilling above me was amazing. With a bit of controlled braking, I stabilized the glider and resumed normal flight.
Lessons Learned and Continued Practice
That experience taught me so much. I realized that recognizing the early warning signs is absolutely crucial. Now, I pay much closer attention to the feel of the brakes and any changes in airspeed. I also learned that the recovery is quicker and smoother if you react promptly. Since that initial training, I’ve practiced stall recovery regularly, refining my technique and building confidence. It’s not something I enjoy doing for fun, but I know that if I ever find myself in a stall situation, I’ll be able to react quickly and effectively;
Another time, during a soaring flight near Annecy, I encountered some unexpected turbulence. A strong gust hit the wing, and I felt that familiar “mushy” feeling in the brakes. I instinctively released the brakes slightly and adjusted my weight, preventing a full stall. It was a perfect example of how practicing stall recovery can help you avoid a dangerous situation in real-world conditions. So, take it from me, listen to your instructor, practice diligently, and always prioritize safety. Those training exercises could save your life.
