what is class of a330 and a359? i couldnt find on ifatc.org
Above is a spawn size chart for IF :)
Both A330-300 and A359 are class Echo aircraft. Can confirm that ifatc.org does not show those aircraft as a reference of their own class.
For future reference, check the table that Manav linked above or see this IFATC Education Group post about the ICAO Aerodrome Reference code
