Great

It worked just fine

Great App

This is a handy app for any flight deck.

Simple, handy and effective

This app takes the guess work out of decoding ICAO Q code type NOTAMs. Simply enter the Q code at the top of the apps' page and it decodes the NOTAM in plaing English. Text size slider makes readability a breeze. 5/5

Great App

Instead of looking up the specific Qnotam I now have a quick and easy way of looking them up. Awesome app. Thanks.
