A bug has been found in the ACARSData.class.php file that has been preventing the aircraft type to be included on the vaCentral live map. The fix can be found here -> https://github.com/DavidJClark/phpvms_5.5.x/commit/0b60a4797a4c4532bb5ff2c1010bc87bdbd1e859
Thank You to Duncan White for this find.
