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.
