Great

It worked just fine

Great App

This is a handy app for any flight deck.

Bof bof

Je n'ai trouve aucun des terrains cherches, dont par exemple LFPN..., assez grand terrain de la région parisienne.

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.
