The contract
horiznlab is a community-sourced planning and orientation tool. It is not flight instruction, not a regulator, and not a substitute for local knowledge. Anything that looks like a verdict on this site is at best a strong indicator — never a license to launch.
How to read what we show you
- Spot data is community-contributed. Wind windows, access notes, landings, and approach descriptions can be wrong, outdated, or seasonally invalid.
- Aspect is not wind direction. Slope orientation tells you which way the terrain faces. Whether wind reaches the launch flyable depends on terrain funneling, venturi, gradients, rotor, and local systems that can flip in minutes.
- Multiple weather models is not multiple weather realities. Agreement reduces model-bias risk; it does not reduce micrometeorology risk.
- Airspace coverage is partial. NOTAMs and class boundaries shift. Always check the authoritative provider for your region before launching.
What you are responsible for
- Deciding whether to launch, fly, and land.
- Assessing your own skill, equipment, and margins for the conditions.
- Respecting locals, nature, and parking access. Violations get sites closed for everyone.
- Reporting anything unsafe, illegal, or wrong via /report.
How we close the loop
Stewards review spot intel. Moderation reviews public content. Reports route to a queue with audit trails and operator review — not a void. If you see something wrong, telling us is the fastest path to fixing it.
