Terms of use

Last updated 2026-07-19.

Buying SQUELCH gives you a personal, non-transferable license to install and run it on your own devices, under a one-time purchase. You may not resell, redistribute, or reverse engineer the app.

SQUELCH is a training aid, not a substitute for instruction from a certificated flight instructor. SQUELCH is not affiliated with or endorsed by the FAA, Microsoft, or Asobo Studio. Microsoft Flight Simulator is a trademark of Microsoft Corporation. Trademarks are property of their respective owners.

SQUELCH is provided as is, without warranty of any kind. We work hard to keep its grading accurate and its curriculum sound, but we are not liable for damages arising from its use, including any effect on your training, your flight simulator session, or your device.
