shutdown of engines (C525)
When coming to our stand, we usually cut off the engines immediately according the checklist. In the flight safety checklist, it says, however, at "shutdown" that throttles should be cut off after two minutes (original text:"Throttles...off(after allowing ITT to stabilize at minimum value for two minutes)). Now, I've never seen any jet letting the engines run for an additional two minutes when coming to a stop. I was thinking that from touching down until reaching the parking stand, two or more minutes usually elapse with throttles barely above idle so that enough cooling time should be provided for the engines. How do you handle that? And: does it make a differenc if you cut off the engines one by one or if you cut off both at the same time?
Thanks for any input,
Cecco
