Update (20/12/2022) – FS-Flight Control is now directly integrated into ProSim; there is no additional support with Jeehell FMGS; and as some users have reported, failure triggering.
The following information is outdated and FS-Flight Control is no longer recommended for use with Jeehell FMGS.
I have just received word from the author of FS-Flight that their excellent instructor station now has Jeehell FMGS support (failures).
I will not go into detail with the program because Flaps2Approach has done a comprehensive review.
FMGS does not come with an instructor station which allows you to perform behind the scene essential functions for the aircraft such as refueling, pushback and failures. FS-Flight is an option to fill that space.
You can download the program and trial it for 14 days.
