Why you guys didn’t include the Pratt and Whitney 4000 engine you only include two engine types what the Airbus a330 300 one more missing your liver is messing with that engine American airlines Korean Air etc
Laura, the Co-Founder and an Infinite Flight developer, gave an excellent explanation as to why the PW4000 engine variant (and respective liveries) did not come with 21.4. Feel free to check it out below.
I hope this helps explain the decision made by IFLLC.
Have a good one!
