![]() "Jay Beckman" wrote in message news:08tsf.9585$xF6.1071@fed1read01... ... had a front row seat (actully it was an exit row window seat...) for a compressor stall on an America West Airbus while departing Detroit enroute home to Phoenix. Just after liftoff we heard/felt a moderate "bang" and I glimsed some flame out the back of the left engine just about the time the gear was in transit. Captain came on the I/C and said it was due to wake turbulence from the Northwest Airlines aircraft that departed ahead of us. Flight continued to Phoenix without any further issues. Good guess, as to the rich. No air was going through, but I'll bet that fuel was. I was on a flight that must have been the first landing of the first captain's sisters kid, who had never landed anything before. It was overcorrected all of the way down, landed long, and when he put the thrust reversers up and gunned it, it stalled, not once, but twice. My only experience with them, however. -- Jim in NC |

A few years ago, before I started flying, I was on an American flight
out of Houston with a pretty good crosswind ripping across the runway. I was seated near the back of the plane. A couple of seconds after takeoff we heard a VERY loud bang, the left wing dipped momentarily, and we continued on... About 20 minutes later the captain came on and explained they had a compression stall due to, he said, to the wind blowing across the engine. He apologized for waiting so long to explain it, but he said he and the crew were busy going through the manual for the restart procedure. Not being a pilot at the time, I remember thinking that maybe he should have read the manual BEFORE flying the plane :-) |

If it's really true that the crosswind caused the compression stall, I
wonder why we don't hear about a double stall very often. Theoretically, the wind can be strong enough to affect both engines, no? Marco Leon "Wiz" wrote in message oups.com...

What makes me think it was true was the fact that you continued to your
destination. If it was a malfunction, then it would be hard to justify continuing (unless of course you're British Airways an have four engines...). A double compression stall on takeoff would be the absolute worst time for that to happen. I had a roomate a while back that was a flight attendant on the Pan Am 747 that lost an engine (as in "fell off" the wing) on takeoff. Still landed without further incident. And yes, she was quite attractive ![]() Marco Leon "Wiz" wrote in message ups.com... Marco: Don't know if it's true or not -- just what the pilot said...

Theoretically, the wind can be strong enough to affect both engines, no? A gusty crosswind is probably the most common cause of compressor stalls on commercial flights. Of course, that doesn't mean that anytime there's a crosswind that turbofans will be belching fire left and right. It's not that common. You have to get just the right level of disruption in the airflow. With any given crosswind, the airflow to each engine is going to be different, because of where they are situated, so it's unlikely that you'd get conditions conducive to simultaneous compressor stalls.

Theoretically, the wind can be strong enough to affect both engines, no? Because each engine is in a different place, perhaps masked from crosswind by the fuselage, etc. Compressor stalls due to crosswind most often occur, in my experience, at the start of the takeoff run, if you bring the power up too quickly and one of the engines has a disrupted flow it will pop. Once you've got speed crosswind compressor stalls are not too common. Another place you're vulnerable with fans is top of descent. In the 747, if we were at or over about 370 at start of descent it was real easy to stall them. We'd have to bring the power back easy and not all the way. Once below 350 you can bring them back to idle. |

Of course...ALL jetliners are required to be able to complete the takeoff roll after V1 and climb out with one engine inoperative. However, I don't think that the premise in the preceding post was valid....all of the conditions for a successful relight (if indeed it had flamed-out) were still present without having to read a checklist, fuel was ON, ignition was ON, and engine was TURNING. I personally have never experienced a compressor stall that caused an engine to flame-out. Bob Moore ATP B-707 B-727 PanAm (retired) |

I concede that the pilot's explanation of the 20-minute delay before
explaining what happened to the passengers, that they were "reading the manual on how to restart it" may not be valid. I know exactly zip about jet checklists and POHs :-) Just repeating what captain said...
