Safety Disclaimer

Effective: September 11, 2026 (supersedes September 3, 2026)

Important: Read Before Flying

UAS SkyCheck is an informational planning tool. It does not constitute FAA authorization to fly and does not replace the preflight responsibilities required by applicable FAA regulations, including 14 CFR Part 107 and §44809.

1. Not a Substitute for Official Preflight Requirements

All drone pilots operating under FAA regulations are required to conduct a thorough preflight check regardless of what any third-party tool indicates. UAS SkyCheck outputs a safety score and restriction summary to assist your planning. It does not replace:

  • FAA LAANC authorization where required, through any FAA-approved provider.
  • Airspace authorization through FAA DroneZone for controlled airspace outside LAANC.
  • Review of current TFRs at tfr.faa.gov and of NOTAMs via the FAA NOTAM System or 1800wxbrief.com.
  • Real-time weather observation and judgment by the pilot-in-command.
  • Knowledge and compliance with all applicable federal, state, and local regulations.

2. Data Accuracy and Timeliness

The airspace and restricted zone data presented by UAS SkyCheck is compiled from publicly available FAA and government sources and is updated periodically. However:

  • Temporary Flight Restrictions (TFRs) can be issued with little or no advance notice. Always verify TFRs through official FAA channels before flight.
  • Weather data is sourced from Open-Meteo (hourly forecast, uses NOAA GFS/ECMWF data), nearest METAR and TAF stations via aviationweather.gov and the National Weather Service (observed conditions and terminal forecasts), and the NOAA Space Weather Prediction Center (the Kp index behind the GPS-health reading). Conditions can change rapidly; the displayed data may not reflect current conditions at your exact location or altitude. An observation is labeled with its age and its distance from your location; treat an old or distant one accordingly.
  • Restricted zone boundaries shown in the app are approximate. Actual regulatory boundaries are defined in official FAA publications, sectional charts, and the Code of Federal Regulations.
  • Data coverage varies by region. Some local restrictions, temporary events, or newly issued TFRs may not be reflected in the app.
  • Weather may be simulated. If our weather provider is unavailable, the app falls back to deterministic simulated conditions rather than showing nothing. Simulated weather is labeled as such in the result, a banner appears, and the safety score is capped so it can never read as a confident green. It is a placeholder that keeps the airspace half of the check usable; it is not an observation, and it must not be used for a flight decision.
  • Airspace class and tower hours have an age. They are derived from the FAA’s 28-day NASR cycle, and the copy we ship may be several cycles old. This matters most where a closed control tower changes the airspace class: the app reverts a Class D surface area to Class G only where the FAA has published that this specific airport does so, and it shows you which FAA cycle the tower hours came from. Confirm against current NOTAMs and the Chart Supplement before relying on a tower-closed result.
  • LAANC facility maps have an age. The grid that shows the altitude LAANC will approve comes from the FAA’s UAS Facility Map publication and may be up to six months old. Treat the ceiling shown as indicative and confirm in your LAANC provider’s app before flying.
  • Shareable check links re-run the preflight check at the time the recipient opens the link, not at the time the pilot originally ran the check. Conditions may have changed between when you shared the link and when the recipient opens it. Always re-verify conditions immediately before flight.

3. No FAA Affiliation

UAS SkyCheck is not affiliated with, endorsed by, or operated by the Federal Aviation Administration (FAA), any government agency, or any air traffic control authority. A “CLEAR” result from UAS SkyCheck does not constitute FAA authorization to fly.

4. Pilot-in-Command Responsibility

The pilot-in-command (PIC) is solely responsible for the safe operation of their unmanned aerial system. The PIC must exercise independent judgment at all times and must not rely solely on UAS SkyCheck or any other single data source when making a go/no-go decision.

5. Limitation of Liability

SudoKodes LLC expressly disclaims all liability for any flight conducted in reliance on information provided by UAS SkyCheck, including but not limited to FAA enforcement actions, airspace violations, property damage, personal injury, or loss of aircraft. Use of this Service is at your own risk. See our Terms of Service for the full limitation of liability.

6. Official Resources

Always verify with official sources before flying:

Updated September 11, 2026. The FAA TFR list and the B4UFLY service were added to this list, and every address now comes from the same table the app itself links to. B4UFLY is named as a service rather than an app: the FAA no longer publishes one of its own.
