This program would decode most of the aviation/weather reports.

This is a ...

• AIRMET Decoder
• SIGMET Decoder
• Area Forecast Decoder
• METAR Decoder
• TAF Decoder
• NOTAMS Decoder
• Any other encoded aviation/weather report Decoder!

For the contractions, I used the FAA Order JO 7340.2E and for the location identifiers, I used the NFDC Location ID Database. I also added some other contractions from different websites to the database too. When you use the program, it would show you if it's using a "Other" database or not. This is a work in progress and I obviously do not accept any responsibility or liability for the accuracy of the data or the program.
This is an open-source program and you can download the source and the database from this link. I hope more aviation/weather -related programs adopt this (I'm looking at you Avare!). I also hope people stop using contractions in weather reports in this day and age with high speed Internet connections accessible to everyone.
This database and program was prepared by Samic in December 2016.
