Turbo waiting on taxiway. 100+, #8 million in line for takeoff
My one and only rear 'started to thermal runaway' was years ago at Hanscom AFB, when the place had 450+ based aircraft, was DEC helicopters' base, and a wild and wholly place to operate.
One Saturday I was number eight million in line for takeoff, 100+F on the taxiway.
The rear engine started to get hotter and hotter.
"Uh oh," I thought.
I found the trick was to keep about 1,200 RPM or so on the front engine, to drive airflow into the top rear scoop, w flaps open.
My turbo has the big juicy flaps and much more open space under the spinner too.
Since then all fine, never an issue.
