General Disclaimer
The information provided by FreeFlight (“https://www.pararoll.com”) is for general informational and educational purposes only. All information on the site is provided in good faith; however, we make no representation or warranty of any kind, express or implied, regarding the accuracy, adequacy, validity, reliability, availability, or completeness of any information on the site.
The use of any information or tools from this website is entirely at your own risk, for which we shall not be liable. It shall be your responsibility to ensure that any information or tools available through this website meet your specific requirements and circumstances.
Not a Substitute for Certified Instruction
Paragliding, hang gliding, wingsuit flying, and related free-flight activities carry inherent risk, including the risk of serious injury or death. Nothing on FreeFlight is certified training, a safety certification, or a substitute for structured instruction from a certified instructor at a recognised school. Calculator results, general guidance bands, and technical information on FreeFlight are informational only and may be incomplete or not applicable to your specific equipment, site, or conditions. Before you make any decision that affects your safety — whether to fly, what equipment to use, how to interpret a site’s conditions — you should use your own judgment, rely on your certified training, and get an in-person assessment from a qualified instructor or experienced local pilot.
Not Professional Instruction or Safety Certification
Content and tools on FreeFlight, including the Wing Loading Calculator, Glide Ratio Calculator, Sink Rate Calculator, Wind Window & Crosswind Calculator, Thermal Lift & Climb Rate Estimator, and Harness Sizing Guide, are for educational and informational purposes only and are not a substitute for certified instruction, a manufacturer’s published specifications, or an in-person site and equipment assessment. They do not constitute professional flying instruction or safety certification of any kind. The figures and guidance our tools provide are general estimates, not guarantees of safety or performance. Always get certified instruction and an in-person assessment before flying a new site, a new piece of equipment, or in unfamiliar conditions.
Tool Accuracy and Limitations
Calculation Accuracy
Our free-flight calculators and tools provide estimates based on standard formulas, the figures you enter, widely-cited conventions, and common rules of thumb. Results should be used as starting points and planning aids, not absolute values or guaranteed outcomes.
Factors Affecting Accuracy
Actual results may vary significantly due to:
- Equipment Factors: The specific glider, harness, or reserve model, its condition, trim setting, and manufacturer specifications.
- Weather & Site Conditions:Wind, turbulence, rotor, thermal activity, and how each site’s terrain shapes local air.
- Pilot Choices: Technique, currency, decision-making, and how each suits your training and experience.
- Measurement Factors: Self-reported figures, rounding, estimation, and differences between estimated and actual numbers.
Our Recommendations
For best results in your flying:
- Use tool results as starting points and planning aids, not absolute values.
- Always consider your specific equipment, training, and circumstances.
- Get an in-person assessment from a certified instructor before you fly.
- Consult your equipment manufacturer’s specifications for specific questions.
- Compare multiple sources and instructors to improve your judgment over time.
Not Professional Advice
FreeFlight tools and content do not constitute:
- Flight Instruction: Information about technique, gear, and conditions is general only and is not a substitute for structured lessons from a certified instructor. Confirm any technique with in-person, supervised practice.
- Go/No-Go Safety Guidance:Our tools and content are educational only and never replace sound judgment, an in-person site assessment, and a certified instructor’s advice on a given day.
- Guaranteed Outcomes: Calculator outputs are planning aids only and are not a guarantee of glide, climb, fit, or safety.
- Certified Expertise: Our content supplements but does not replace certified flying instruction or safety training.
Consider consulting a certified instructor or your equipment manufacturer for:
- Whether it is safe to fly a given site on a given day
- Your specific glider’s certified wing loading range and behaviour
- Reserve deployment technique and packing schedule
- Manoeuvre training (big ears, spirals, SIV) under supervision
- Harness and equipment fit specific to your body and flying style
Free-Flight Safety Disclaimer
Our tools provide general guidance only. Paragliding and related free-flight activities carry real and serious risk. Always:
- Get Certified Training: Learn from a certified instructor at a recognised school before you fly, and keep training current.
- Respect Site & Weather Limits: Treat wind, thermal, and turbulence conditions with caution; do not assume a general guidance band applies to your site.
- Use Good Judgment: Progress gradually and be honest with yourself about your current skill level.
- Compare Widely:Weigh guidance against multiple trusted sources and your instructor’s advice.
- Confirm With a Certified Instructor: Validate concerns with a qualified instructor or experienced local pilot before you fly.
If you have any concerns about a flight:
- Have significant concerns reviewed by a certified instructor.
- Follow your school’s guidance and applicable site rules carefully.
- Avoid flying equipment or sites beyond your current training.
- Follow safe and sensible pre-flight checks and practices.
- Treat unfamiliar sites and conditions with extra care and caution.
