Sorry for the lack of precision. I had in mind a message posted on August 9th on that forum. I try to translate a small part of that message:
"We are currently trying to estimate the CoG after 3h25 flight time. Roughly the aft limit is 38% MAC and the a/c would have been at 37.7%, yet to be confirmed.
In ALT2 or worse in direct law (we don't know yet) nobody managed to fly this at FL350. Try it in the simulator, it feels very odd, dont forget you don't have airspeed information, you are in night IMC, and with turbulence".
So indeed this scenario is more degraded than what one would understand from my previous message.
