If we already have an Airbus A320-214 (x2 CFM56 engines) in the game:
Why don’t we implement the Airbus A320-232 (x2 IAE V2500 engines)? They’re still the same type of aircraft, one difference of the two are the sounds the engines make and the look of the engines.
Reason for implementation:
Many airlines these days are ordering A320s either with CFM56 engines or IAE V2500 engines.
There are many engine specifications of different types of aircraft.
This is to increase game quality, have more plane types, game realism, more game sounds, among other reasons…
