@Black-Square I've learned a great deal about aviation generally by way of flying your Caravan from Florida all the all over to Scotland where I am now in FSEconomy, I look forward to any future updates/fixes/improvements forthcoming for this aircraft. Even with SU15 and all your various suggested workarounds in previous threads, there still seem to be a few minor AP gremlins: AP screen remains lit when powered off(intended behavior?), some issues with under or overshooting altitudes, but nothing major. That's really the only thing I can think to complain about, and as I said its minor, not game-breaking. Seems to be something about the interaction between the PMS50 GTN750, the WT "layer"(do I even need the Marketplace WT thing now?), and the KAP140 code of the sim itself.
