iFly Releases SP1 for the Advanced Series 737NG

iFly Development Team has officially released Service Pack 1 for their new iFly Jets Advanced Series – The 737NG

iFly has corrected a few issues that were reported after release and implemented some new items based on customer feedback.

  1. The Prepar3D team designed a new HUD draw technique specific to Prepar3D version 5.3. that iFly has implemented. The HUD will not work on any Prepar3D version prior to 5.3.
  1. You will now find a new Livery Download and Installation tool (GetLiveries desktop shortcut) that will make the task more automatic and streamlined. This tool will install liveries uploaded to the Flight 1 Library (  but is also able to do manual installations, provided the painter(s) follow the required guidelines as described in the Paint-kit “Instructions ReadMe.pdf”. You can get the paint kit here:
  1. There is now also an option in the Configuration tool that allows you to have Ground Power connected in the “Cold and Dark” state. This allows you to enter the cockpit at the gate with Ground Power already connected. It also helps VR users so they do not need to open 2D drop down menus. This option is enabled per installed Livery.
  1. You can now keep the aircraft sound unmuted when Prepar3D loses focus.
