Hi DW,
As such, there's no guarantee that such artificial feel systems will behave transparently if an aircraft is taken outside the normal operating envelope,
It's not so much the magnitude of the force feed back which matters - it's the displacement away from neutral on the controls which gives you the clues as to how far away from your trimmed position you are.
B777 and B787 have a large red switch to turn the FBW computers off and enable the pilot to simply fly like like a 707, 737, 757 etc. Airbus don't fit a similar switch.
