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

[Cecil Acuff]

Beat me to it...

A simple stall is one thing a FOD'd engine is another story.  But a restart 
might get you enough power to get you back to the field...it you don't have 
an engine fire in the process....

Andy,

They "can" be restarted in flight.  The difficulty is that you CANNOT
tell if it was a "simple" compressor stall OR did you just ingest as bird.

After the "Miracle on the Hudson", mental priorities and possibilities
have changed.  The awareness is different.

It is up to the Pilot in Command, PIC, what flows and what goes.

He can tell ATC, a ground controller, and approach control to "stick it"
IF he feels safety isn't being adequately addressed, or other issues.

I ran into this my self twice when I flew as PIC.  Once I simply told
the Tower to wait - My hands were full due to clear air turbulence that
drifted over MY runway from a flight that took off over 5 mins earlier.
The "heavy" had left its wake, and the crosswinds had blown it over to
my runway.  The Tower had NO way of knowing what I was fighting.  Then
again, they weren't paying attention to the position of the ailerons and
rudder.

The second one was when they told me to turn downwind into traffic they
had cleared another aircraft inbound.

It just happens!
