For any CRJ drivers out there - would it be normal to shut down an engine immediately after clearing the runway to save fuel? Would it make sense on a hot day in Denver? Or, would there be a cool down period required with these motors?
I've seen many engine shutdown policies come and go over the years to save fuel and in some cases brake wear.
In my experience, both personal and anecdotal, two times that engines are more likely to catch fire is when they start and when they are shut down.
