Contact

Email contact@aviationcalculators.com.

There is no contact form on this site, and that is deliberate. A form needs a server to receive it, which means somewhere holding your message and your address. A plain email address does the same job without any of that.

Reporting an error in a calculation

This is the most useful thing you can send. If a number looks wrong, include:

• Which calculator, by name or by link.
• The exact inputs you entered, including which units were selected.
• The answer you got, and the answer you expected.
• Where your expected answer came from, if it was a published figure or another tool.

That is enough to reproduce the problem straight away. Corrections to a calculation are treated as urgent.

Suggesting a calculator

The set of calculators here is fixed and fairly deliberate. Takeoff and landing performance, weight and balance, and anything that produces a go or no go verdict are all excluded on purpose, because they need aircraft specific approved data. Suggestions outside that boundary are welcome.

What this address is not for

No advice is given on specific flights, and nothing here is a flight planning service. For anything operational, use current official weather, your aircraft flight manual, and the published rules for your flight.
