John, on just about every sim I’ve even been involved with there is just this freeze function. For want of a better description, ‘Recoverable Crash’ parameters such as excessive G, IAS, Mach, Taxi speeds, Tailstrikes and ‘Irrecoverable Crash’ parameters such as excessive pitch/bank/side force at touchdown are monitored. Typically a Crash page is displayed on the Instructors station when any parameter is exceeded and if not inhibited by Instructor selection, the sim freezes.
Unfortunately from my observations, most instructors do indeed inhibit this feature.
Whilst I have never seen the vibrating seat you describe, it was fairly common for helicopter sims to mount the cockpit on a frame separate from the normal base frame and use a small jack to provide the vibration effect independent of the motion jacks.

I’m not a Flyt expert. Maybe Mad Scientist who is would respond. Interestingly, whilst there is a tolerance for inertia in sim specs, I can’t seem to find any reference to it in JAR-STD-1A.
All axis rates really should be very representative. As you state, most line pilots will never experience actual engine failures and sim training in this area is their only exposure to this.

Appears your sim experience understandably was not a happy one. Sims that perform like this should not remain in service as negative training is received. What does surprise me is that your TRI/TRE didn’t do something about it.
Your comments on systems simulation are very valid. As has been stated before on this thread, there is no excuse for anything less than perfect simulation in these areas. How does this get by? I really don’t know. Assuming it was never correct, the blame must rest jointly between the sim manufacturer, the acceptance team and the initial certification team.
If however the sim fidelity has deteriorated, then my own discipline is solely to blame.
I am very surprised that the sim instructors do not do something about it.
As for your rantings. I disagree. Your comments are entirely justified. Hope you get home soon.
