Purpose of AviationCalc:

Allowing the app access your location will only allow the app to help get better precision on which Time Zone to use. Click on info button (bottom right) to pull up how-to-use alerts or whenever you want to change the regulatory institution or choose a different time after flight duty for total duty period calculation. If there is something wrong going on, tap the screen again.
