@DireBasilisk19 while you wait for the wide body Boeing jets and/or the A320 to be fixed/patched/released as study level payware, do yourself a favor (if you have not already), and check out the Cessna Cj4 by working title. Available here:
It is a jet, with a great flight model, fully functional FMC and Flight Navigation system that they built from scratch (with optional sim brief integration). Functional FADEC, VNAV, LNAV, Holds, custom weigh points, RNAV approaches and the list goes on… It is still in beta, but the autopilot is rock solid and is able to follow a flight plan and calculate TOD etc… and it is awesome fun to fly.
