flight_warning.py
version 1.06
Copyright (C) 2015 Darren Enns <darethehair@gmail.com>

=======================================================================
Changes:
=======================================================================
transit_warning_v0.4 Grzegorz Tuszyński <grztus@wp.pl> (May 2024)
- added MLAT messages handling
- added automatic port connection to ports 30003 (ADS-B) and 30106 (MLAT) (nc or ncat is no longer necessary)
- added a 120-second display of transit information to allow time for taking a photo, and then returning to verify the separation from the Sun/Moon.
- code optimization and improved robustness

TO DO LIST:
1. add vertical speed and pilot selected altitude to transit calculations
2. add some logging functions


v0.3 Grzegorz Tuszyński <grztus@wp.pl> (May 2024)
- auto checking the pressure from metar (for Poland region. You need to find some metar url site for Your country and change proper lines below in the script)
- minor bug fixes (including some calculations)
- added support of python 2 and python 3 in one script
- fitted to work both on Windows (10 Pro) and linux debian (10) systems
- more comments as user instructions added for better understanding the script

v0.2 
- try/except for plane lat/lon in MSG 3
v0.1
- Color console realtime display Az/Alt
- Sun/Moon transits prediction
