Marwan Gharib’s HJET gets a big update with improved autopilot and navigation, general fixes, and more

The HJET is undeniably one of the best airplanes currently available for Microsoft Flight Simulator, a brilliant combination of stunning visuals, deep and realistic systems, and the useful performance and versatility of a small, fast jet. FlightFX and Marwan Gharib continue to provide the necessary support to keep the aircraft updated and running smoothly for every user, and have just launched a big update that brings a series of important improvements.

The bulk of the new changes is related to the autopilot and navigation systems of the HJET, which are areas that have seen some complaints from users, particularly the autopilot behavior in VNAV mode. Thankfully this behavior should now be much improved, as this new version of the HJET brings with it a rewritten VNAV logic that should be more reliable and accurate. Hopefully, no more unexpected descents when clicking the VNAV button!

Besides numerous improvements in the autopilot and navigation systems of the HJET, this update also brings some tweaks to the flight model (ground effect during landings should now be less pronounced), but also some miscellaneous changes across the board.

If you’re a fan of the HJET either on PC or Xbox, make sure to grab your update in the MSFS Content Manager. The full release notes are below, and the developer even keeps a public list of issues being tracked with estimates for a forthcoming patch. Check it here to see if any particular problem you’re experiencing is being fixed in an upcoming update!
