Beside the main functions AITM offers some other small goodies:
This function will calculate the distance between two given airports in miles.
This function will create a file named "New Airlines.cfg". This file then contains localized versions of all available FS2002 regions and countries.
This function will delete a file named "AFDCache.dat" from the AITM program folder. This files includes a list of your airports and the regions and countries they belong to. You should delete this file everytime you installed or modified a Scenery in FS2002.
This function will turn on/off the AITM logging.
Shows or hides the TTools compiler. Sometimes it's necessary to turn it on, because otherwise you wouldn't see any compiler error messages.
