Frequently asked questions
Are the tools free?
Yes. All calculators are free, need no account and run entirely in your browser. No cookies are set and nothing you enter is stored.
Can I use the results for my flight?
They are planning aids. For the flight itself the POH/AFM of your aircraft, the AIP, current NOTAMs and the official weather briefing are authoritative – the pilot in command decides.
Which languages are available?
Every tool is available in English, German and French; the METAR/TAF decoder writes the plain-language text in the language of the page.
