Beyond the Fabric: From Entry to Expert - A Guide to Paragliding Wing Classes
Paragliding wings, often called "gliders", are incredibly sophisticated pieces of equipment designed for specific pilot skill levels and flying styles.
All wings hold certification ratings, mainly the EN (European Norm) system.
Here's a breakdown of the main types of paragliding wings:
1. By EN (European Norm) Certification Class:
This is the most crucial classification system, guiding pilots in choosing a wing appropriate for their experience and skill level.
The ratings are based on how the wing behaves during various simulated incidents (like collapses) without pilot input, and how easily it recovers.
EN-A (Beginner / School Wings):
- Maximum passive safety, very forgiving, highly stable, and predictable in unusual flight conditions. They tend to recover from collapses quickly and often without pilot intervention.
- Typically has a lower aspect ratio (shorter span, deeper chord), fewer cells (internal compartments), and robust construction.
- Students, absolute beginners, and pilots who prioritise maximum safety and relaxed flying.
- Many experienced pilots also keep an EN-A for casual flying or strong conditions.
EN-B (Progression / Intermediate Wings):
Offers a good balance between performance and safety. They are more agile and performant than EN-A wings but still provide a good level of passive safety.
Slightly higher aspect ratio, more cells, and a more refined aerodynamic profile than EN-A wings.
Sub-categories:
- Low EN-B: Closer to EN-A in terms of passive safety, a great first wing after school.
- Mid EN-B: A true intermediate wing, offering good performance for cross-country with manageable demands.
- High EN-B ("Hot B"): These can approach EN-C performance, requiring more active piloting and having more dynamic reactions to turbulence, but still with good recovery characteristics
Pilots transitioning from school wings, those beginning cross-country flying, and experienced pilots who want good performance without the high demands of higher classes. This is the largest and most popular category.
EN-C (Advanced Wings / Sport Class):
- Designed for experienced pilots who want significantly more performance (better glide, higher speed, more precise handling) and are comfortable with a lower degree of passive safety.
- Higher aspect ratios, more cells, and often more complex internal structures. They are more "talkative" (transmit more feedback from the air) and require consistent, active piloting.
- Committed, experienced pilots who fly regularly have a solid understanding of active piloting and are looking to push their cross-country limits. Not suitable for new pilots.
EN-D (High Performance / Competition Wings):
- Top-tier performance wings designed for expert pilots and serious Paragliding Competitions. Passive safety is significantly reduced; they demand constant, highly active piloting and swift, precise reactions to collapses.
- Very high aspect ratios, many cells, and often advanced internal bracing.
- Professional or semi-professional competition pilots who train extensively and possess exceptional flying skills and judgment.
CCC (Competition Class):
- The absolute pinnacle of competition wings. These wings are built for maximum performance with almost no passive safety. They are not officially "certified" by EN in the same way, but follow a "Competition Class Compliant" (CCC) standard for competitive fairness.
- Extreme aspect ratios, incredibly high cell counts, and often incorporate rigid elements in the leading edge.
- Only the most elite, full-time competition pilots.
2. By Construction / Design Philosophy:
Beyond the EN rating, some specialised wing types exist based on their construction:
This is the traditional design, with an upper and lower surface forming air cells that inflate to create the aerodynamic profile. The vast majority of paragliding wings fall into this category across all EN classes.
Single-Skin Paragliders:
These wings have only an upper surface (no lower surface for the main part of the wing, though some cells might be enclosed). They are incredibly lightweight, pack very small, and are extremely easy to launch in light winds. They are also very stable in pitch.
Trade-offs: Generally have lower glide performance and speed compared to double-skin wings, and their precise handling can be different.
Hike & fly, mountaineering, and specialised lightweight applications where portability and easy launch are paramount. They often fall into the EN-A or low EN-B category for passive safety.
Hybrid Wings:
A blend of single and double-skin design, aiming to combine the best attributes of both. Some cells might be single-skin while others are double-skin, or they might have unique internal structures.
offering improved performance over pure single-skins while retaining some weight and packing advantages, or to achieve specific handling characteristics.
Mini Wings / Speed Wings / Speed Riding Wings:
These are very small (typically 8-15 square meters), highly loaded wings designed for high speed and rapid descent. They are not designed for soaring or thermalling in the traditional sense.
Used for "speed flying" (very fast, close-to-terrain descent) or "speed riding" (combining skiing with the wing for high-speed turns and jumps on snow).
Very dynamic and demanding; only for highly experienced pilots. They are usually uncertified or fall into a specialised category outside standard EN ratings.
3. By Purpose/Application (often overlapping with above):
Tandem Wings: Large, robust, and highly stable wings designed to safely carry two people (a pilot and a passenger) or also known as Tandem paragliding. They are typically EN-A rated for passive safety.
Acro Wings: Smaller, highly specialised, and extremely dynamic wings designed for performing acrobatic manoeuvres. They are uncertified or fall into a specific "Acro" classification due to their extreme nature.
Paramotor Wings (PPG): While they use a similar design, paramotor wings are often reinforced, have trim tabs to adjust speed, and are specifically designed to be flown with a motor unit. They also have their certification standards (e.g., DGAC in France) that focus on different parameters than unpowered flight.
4. Materials:
Paragliding wings are constructed from advanced, lightweight, and durable materials designed to withstand the stresses of flight and varying weather conditions.
Fabric:
The primary material for the wing's canopy is typically a ripstop nylon or polyester fabric, often coated with silicone or polyurethane for airtightness, UV resistance, and durability. These fabrics are carefully chosen for their specific properties, including:
- Porosity: The fabric must be extremely low in porosity (air permeability) to maintain the wing's internal pressure and aerodynamic shape. Over time, fabric can become more porous, affecting performance and safety.
- UV Resistance: Sunlight, particularly UV radiation, can degrade the fabric's strength and coating. Manufacturers use UV-resistant treatments to extend the wing's lifespan.
- Tear Strength: The ripstop weave helps prevent small tears from propagating, increasing the wing's robustness.
- Weight: Lighter fabrics are used for performance and hike-and-fly wings to reduce overall weight and packing volume.
Lines:
The lines connecting the pilot's harness to the wing are crucial for control and load distribution. They are typically made from high-strength synthetic fibers like:
- Dyneema (HMPE - High Modulus Polyethylene): Extremely strong for its weight, highly resistant to abrasion and UV, and has very low stretch. It's common for main lines.
- Aramid (Kevlar/Technora): Also very strong and has excellent dimensional stability (low stretch). Often used for cascade lines (inner lines) or areas requiring minimal stretch.
- Polyester: Sometimes used for outer sheaths on lines for increased durability and abrasion resistance, especially for lines that are frequently handled.
Lines are usually unsheathed (bare) for performance wings to reduce drag and weight, while beginner wings often have sheathed lines for better durability and easier sorting.
Internal Ribs and Diagonals:
Inside the wing, a complex structure of fabric ribs and diagonal supports defines the airfoil shape and distributes stress. These are also made from lightweight, tear-resistant fabrics, often with stiffening materials in the leading edge.
Plastic Rods/Nitinol Wires:
Many modern wings incorporate flexible plastic rods (often nylon) or super-elastic Nitinol wires into the leading edge and sometimes across the chord. These help maintain the perfect airfoil shape, improve launch
