Nozard Flight Plan is a tool that will help you generate an ICAO flight plan message to send to your ATS Reporting Office (ARO).
This is a minimum viable product. It will not send the flight plans for you, but will launch your devices email application with an almost totally prepared to send message. It will not determine an appropriate e-mail address for which to send the message. Please consult official aeronautical information sources to find the ARO email address to use.
