Vin Rouge,
"Even with FADEC, MGT/EGT overtemp can be an issue, especially if you are operating close to the aircraft max operating envelope"
Today's FADECs do not have overtemp protections? Seems this would be something designed into them. Doesn't the T5 sensor, ITT sensor, EGT sensor, or whatever is in use provide an input to the computer, which then reduces fuel flow to keep temps at or below the maximum?
