It is quite strange, Nabeel, that you don't know what you have created
Look. To get flight plan from VA site, fsacars.php script is called with argument "flightplans" - FPSite=http://yoursiteaddress/phpvms/action.php/ACARS/fsacars/flightplans (can be without /phpvms/ if you use root for engine.
But if you would look to fsacars.php, you wouldn't found such action. You can find only 'acars', 'schedules', 'status' and 'pirep' here.
So downloading FP from VA is not implemented in current version at all, while VA configuration file has string for it.
