What is " manual engine ignition?"

Certainly all the ingredients are there for such event to happen.
Lets see ... Decending = Low Power Setting (lets call it "little flame") Airspeed - If no turbulence, guessing it at 220 kts or even a tad more. This is not helpfull for the "little flame". Then the freaking flood of water comes in (Heavy Rain) ... et voilá ... puts out the "little flame", or we have "Flame Out". The crew selected manual engine ignition for the remainder of the flight |
I thought engaging "continuous ignition" was always standard procedure when encountering heavy precip. Just in case. As in Wiedehopf's link.

That’s where the igniters are turned on manually. I don't know why but it conjures up an image of the co pilot reaching out the right window with a BBQ gas lighter in hand , calling " Fire in the Hole", then handing the lighter to the skipper to do the same on his side. LOL. Merry Christmas to all. :-) |
It's worth noting, continuous ignition won't prevent a flameout - however it improves the odds that the engine will quickly recover.

The NTSB report criticised the captain for relying on his weather radar to navigate through a thunderstorm. Faulty engine handling was a contributory cause of the severe damage and eventual loss of both engines.

At least the ATR crew restored power to both engines.

The SO242 engine mishandling was the increasing of engine power to regain altitude with both engines surging due to the ingestion of hail. Different events include different combinations of results.

Just nitpicking, but according to the preliminary report linked in one of the early posts the engines restored power automatically by themselves. Only after the second engine went through a flame-out/automatic relight cycle did the crew turn on the continuous ignition. Which might not have prevented the flame-outs anyway.

What would be so particular about this event that has not been flown over so many years of service? I suspect that this was not the first time this aircraft had descended in heavy rain.....

Just a question really but why is it that the automatics have authority to command a relight but do not have authority to command continous?
