Confirmed, as so we can all move on, reference attached. And for the guy that flew 767\x92s for 40 years and didn\x92t know anything about it 😂

Condition: Engine speed for both engines is below idle

Fuel Control Switches (both) \x85 CUTOFF then RUN
RAM AIR TURBINE switch \x85 Push and hold for1 second

The above checklist procedure implies throttle lever angle and cutoff switches are independant for resetting FADECs.

If so, is it time for this convention from the days where throttles and cutoffs were mechanical systems, not resolvers and switches, to end?

Risk vs reward? Requires more coordination between PF and PM in cases where cutoff is not desired by PF- keep throttle/s up, cannot be surprised by a fuel cutoff.

Yes, switch directly controls spar valve (fuel supply) position - no fuel - no fire.

Not entirely correct, the engine fuel valve is controlled by fire handle, the spar valves are at the tank. See attached.

You get an EICAS message when you set the fuel switch to CUTOFF - something like "ENGINE X CUTOFF" (not sure of the 787 wording, but it would be something to that effect.

While I doubt the PF would be actively monitoring EICAS during TO, with the sudden audio change to the engine noise as well as the sudden loss of acceleration, I'd expect him to take a quick look at EICAS to see what the ( ) the engines are doing. Plus, if the PF was in the right seat and his PFD blanked - I'd expect him to look across to see what's on either the standby or the left seat PFC, and perhaps EICAS.

It would have been a Christmas tree of EICAS alerts

CVR should have recorded the beeper too, inhibits are for ground only.
