"To be a true, 100%, Full Authority Digital Engine Control, there must not be any form of manual override available.
False - the fire handles are hard wired through to the fuel control unit.
Probabally agree (?) with your statement as it stands however you were a wee bit selective in your cut and paste
Full quote reads.....
"To be a true, 100%, Full Authority Digital Engine Control, there must not be any form of manual override available. This literally places full authority to the operating parameters of the engine in the hands of the computer. If a total FADEC failure occurs, the engine fails."
I think the key words here are operating parameters i.e normal operation not emergency.
