PSA CRJ incident

Cont. Ignition kicks on prior to the shaker actually.

I honestly have to get in the books and see what it does on our 601. From training when we're doing stalls we have the ignitors on as a pre-maneuver check so I can't remember.

Edit: I just looked it up and it's the same on the 601.
 
Can someone enlighten a piston guy as to all of this? Do the igniters kick on because there's reduced airflow going into the engine? Does having the igniters on too long with not enough airflow make the thing heat up enough to do this kind of damage?

Gracias. I don't know too much about that turbine wizardry.

The 200 has speed controllers on it. As long as they are working (and I've only seen one MELed once or twice in 8 years), they should prevent the engine from overspeeding and the ITT getting away from you. I've RADAR powered the plane twice during honest to god 40+ knot losses at 200 and 400 feet and both times, although we did get red flashing alerts on both engines gauge sets they did not melt and I think all 4 engines passed an inspection after we landed.

This is good to know, too.

I'm just a turboprop punk ;)

Igniters being on only provide some spark in case the fire goes out. Heat-wise, having them on has no effect other than wearing out the ignitor.

Not quite. The angle of attack vane (1 on each side of the forward fuselage) senses a high AOA (obviously) and will send info to the stall computer which activates the continuous ignition.

Evidently, neither did the PSA pilot dudes.

We have a procedure in the 757.

Axe me why we have that! :)

One time, at band camp... or on departure out of SNA many years ago... (wasn't me!)

The Delta 767-200 on climbout from LAX, relatively low altitude over the water after taking off to the west. Got REAL quiet. They moved the EEC switches (or whatever they are called on the CF6-80A, don't remember) to the overhead panel after that one!

Kinda, but the engine, departure airport and the scenario is wrong.

But close! :)

That was a LOOOOOOOOOONG time ago. To think they were mainline pilots just scares me. :)
