http://avherald.com/h?article=4f0372a2&opt=0
Re: Kalitta shutdown/restart:
Shutdown seems a bit excessive. Why not just pull it back to idle? Who knows if another engine is going to die - you're going to want that thrust RIGHT NOW, not in 3 minutes.
Good question.
Maybe they wanted the FMC to be in 1 E/O mode, so that the FMC can compute the fuel and ETA predictions and the altitude profile correctly. One engine at idle would keep the ALL ENG mode, and the predictions and altitude profile would become incorrect.

I actually tried this in PSX. By telling the FMC manually an engine had failed (ENG OUT>) it seemed to compute the same data as when the engine was completely shut down? The only difference was with the engine shut down, it displayed the re-light envelope on the upper EICAS.

Yes.
You mean, instead of shutting down the engine they should've selected ENG OUT on the FMC and just put that engine to idle?

The GC distance is 3479 NM between the airports. They'd already been airborne over an hour before spotting the issue, so it had burned around (guess) 8,000 lbs or so of fuel out of its tank (I assume it took off like this as well).
That put it about 3000 NM from Miami when they found the problem. At 500 kts that is 6 hours flight time. Idle fuel flow is 1100 lbs or so per hour, so a further 6600 lbs would be burned over 6 hours at idle.
Total burn would be ~10,000 lbs (or around 33% the #1 tank fuel capacity) at the point they noticed the problem.
At the point in the flight where they reach 80,000 lbs of total fuel remaining, they could resume normal operation of the engine.
In the meantime, they still have it as a backup for numerous systems (electrical, hydraulic, pneumatic, and of course, thrust).
I don't see that shutting it down actually benefitted them, except to save a literal 3000 lbs or so of fuel (and not even that much, as they would be burning more fuel dragging a dead engine through the air).
In my unscientific test, PSX requires about another 0.5 units of rudder trim for an outside engine that is shutdown vs. idle, once established at the D/D altitude/speed (in my test GW was 640,000 lbs and DD alt was FL339 @ 262 kts).
All it seems to have achieved is a higher fuel quantity in the tank at the point where they could use the engine normally, but otherwise, I only see downsides.
I think it also counts as an in-flight shutdown event for the engine, so that's not good, either.
Regarding the risk of a failing restart of a good engine: Is that risk really so high that you want to keep that good engine running by all means? I don't know, but perhaps you could also invert the risk evaluation and say that it's safer to shutdown all engine accessories in case of a fuel leak within the engine system, so that you have more fuel available at the end in case the situation gets worse.
Quoteperhaps you could also invert the risk evaluation and say that it's safer to shutdown all engine accessories in case of a fuel leak within the engine system, so that you have more fuel available at the end in case the situation gets worse.
AFAIK there would be no reason to suspect a fuel leak (though they perhaps thought this initially)?
With the fuel being trapped in tank 1, saving it doesn't make much sense beyond fuel balance if it was leaking with a running engine for some reason.
Let's add some more, eh, fuel to the discussion.

QuoteIncident: Longtail B744 over Atlantic on Apr 11th 2022, thrust lever causes engine shut down in flight
I see the thrust lever "potentiometers" are only dual channel. There is a signal comparison between the two channels.
There is also a value range validity check and a "sin^2 + cos^2 = 1" test.
Loss of proper data will result in:
idle thrust if mach <0.15
last known command if mach >0.15.
Interesting reading and facts!
Btw: congratulations Hardy, on your 13K posting! ;)

APU pipe?
It would be nice if Atlanta could donate this pipe to the garden owners so that they can put flowers into it.
Looks like Engineering didn't latch the APU access doors properly. Not sure how the doors took out the tailpipe though. It sits embedded in the tailcone.
Will be intersting to find out what caused this as most cowlings and compartments have pressure relief doors.
Quote from: garys on Sat, 10 Sep 2022 14:20Will be intersting to find out what caused this as most cowlings and compartments have pressure relief doors
If unlatched, the door halves will simply drop/hinge downwards and get caught in the slipstream and will be torn off by aerodynamic loads.
Looks like it was a PW L/H core cowl again similar to this one https://avherald.com/h?article=4b571308
