On the 737, the Isolation valve is used for a different purpose but the bleed Air SOV would be closed at some point. First things first, maintain aircraft control. let it burn. Engine shutdowns come a little farther down in the procedure. maybe after 2 or 3 minutes into the emergency. Usually takes a minute or so to accurately assess what’s happening and keep the airplane out of the dirt, declare the Emergency and come up with a plan. Then start running checklists, and securing engines or whatever the Emergency is. So 10 minutes to get back on the ground can seem like an eternity.
Thanks again!
I was on a commercial flight that was struck by lightning & later said something to a friend about the captain not getting on the speaker & they said a strike might have set off a bunch of alarms that they needed to address.
