[R-390] Compressor stall (nee Cosmos Dis-assembly)

[Jim Temple]

Barry, jack of all trades. You seem like an emotional sort of guy. You think
and judge, clearly, from emotion and not from facts. You expressed no facts.
You have no idea what the issues were surrounding the PATCO labor dispute,
and what was at stake during that time in history. It sounds like you just
think it was, simply, a them against us thing, and they got theirs. Amazing
how people like Barry are still fighting political wars from decades ago. 

Now that Barry got his political hit piece in, and I responded, we need to
get back to R-390's.

I've not heard of a turbine that doesn't have an engine restart 
procedure. Even the lowly helicopters I flew had them. It may take 
several thousand feet to get it restarted, but they are meant to 
restart. Having some sort of failure or damage changes things somewhat. 
We practiced those over and over in the simulators.

I had small compressor stalls only once. I was flying nights with 
goggles with students in Alabama. We were flying around 400' over the 
trees. I was a brand new night instructor and still a little nervous. I 
went for the first field I saw when I realized it was stalling over and 
over. As soon as I got close to the ground and saw the big transmission 
lines, I did exactly what you aren't supposed to do. I pulled in full 
power to get out of there before hitting the wires. That turbine ran 
like a champ until I set down about a mile away.

The plane over the Hudson didn't have near the altitude needed for a 
restart attempt.

Declining ATC suggestions? I've turned down directions more than a few 
times. Sometimes, they are just lollygagging around the air conditioned 
tower, and are clueless. The best thing that ever happened was when 
Reagan fired the striking controllers in PATCO. The radio traffic 
instantly became friendlier and more helpful. The bad ones were gone and 
it was fun to talk to ATC once more.

It also depends on what controller level you talk to. Centers like 
Atlanta are the best and rarely mess up. You know you are in good hands 
with those guys.
