Automatic Fadec shut down and N-1 ferry permit.
I start with the end: Never and Never.
Tdracer is the expert and he has spoken.
The PW on the Do328 jet would cut the fuel at 108% if the two other overspeed protection system had failed controlling the overspeed condition.ONLY to introduce fuel as the engine got under control , something that posed majore controleproblems as the engine cycled from 108% idle and 108% over a ca 30 sec time.
All fun and games in the sim.
No FADEC is certified to shut down in the air. periode.
Had a Yank in the sim once that wanted to simulate a ferry flight with one engine.
Why ever do You want to do that? Was my question! Shure it can be done He say! OK ! Go for it.
First he showed me how the Dornier was an expensive lawn mower, then he fed in power gently over 600m runway accelerated to v1( not that consept was valid anymore.and climbed away at V2 with a grin on his face.
Having used ca 2500 meters runway.
We then proceeded with two engines and he did a roll.
(Something that HAS been done with a 328 by Air Engedina on a ferry flight, observed by an offduty Swiss CAA Guy , OOPS!)
With that out of his system we vent for coffee and we decided to Get With The Program.
