quite a few holes in that piece from an apparent professor. However lets assume its genuine.
For the 6,000,000,000,000 million billion time, there could be a weeks delay in sending the acars messages they will still show aircraft system time taken from the aircraft reference clock as indicated at the time of the event. I don't know how to make that any clearer.
ISIS is not just a laser ring gyro. It also has pitot/static inputs from the systems being logged as faultly. Maybe thats why it logged a fault message
The one message that remains puzzling is the ir fault. Perhaps yes because the aircraft had already exceeded some limits but that is pure speculation.
