Turbo cool down periods?
Really?
no
SERIOUSLY!!...
So lets examine your 'cool down'
You taxi in. Come to a stop and set 1000 RPM and wait 3-5 minutes, then shut down. Are you bothering to monitor your engine instruments and watch what is happening? Nope, most do this without any thought, and are too busy gathering up all their maps, putting headsets in bags etc and preparing to depart the aeroplane.
Lets examine 'immediate shutdown'
You land, and taxi back to your parking bay. Normally what 800-1000 RPM. ?? any more than that and your going to ride the brakes. So your trip back to parking takes what 3-5 minutes?
So please tell me, how much cooler the turbo is going to be if i taxi in and wait another couple of minutes at 1000 RPM????
Cheers
