Traffic_Creator.py can be run either through an IDE or directly from the directory via the command line/terminal by typing "python3 Traffic_Creator.py" without the quotes.
You can create as many aircraft and flights as you wish by filling in the details then pressing the "Create Aircraft Section" then each "Create Flight Section", this process can be repeated as often as you like but remember to alter the relevant details so you don't end up with duplicate flights. Comments can be added anytime they are required.
**Do not close the program until you have finished all tasks and saved the file as this will wipe all data.** Saving the file will automatically close the program.
This is not an xml editor, it can not edit traffic files, I created it to quickly write test or local files so it's not really a program for writing or editing airline schedules.
