Bleed Air Shutoff synonym

[GravityHater]

I am studying a new type and it has a Bleed Air Shutoff just below the glareshield. (type withheld for privacy reasons)
Anyway, reading the manuals of course it goes into great detail about what it is and how to use/misuse it. It sounds just like what I have always learned as a Firewall Shutoff Valve electric switch. I just wondered about the history of the nomenclature... or is there a specific difference between the BAS and the FWS?
Its a PT6.
It closes off way more than just the bleed air, why do they call it bleed air shutoff if it shuts off the fuel, electrical, hydraulic, air etc etc.?
Thanks.
Plain nasty replies will be filed for future reference!

LOL!

Schooled. :beer:


It sounds like just a normal fire handle/button function if it does all the usual stuff (bleed air, fuel, generator, fire bottle, etc). Maybe it's referred to as a Bleed Air Shutoff since some PT-6 applications don't use bleed air? I flew a PT-6 a long time ago, but I can't remember what the button was officially called.

I guess I have no answer for that, give yourself 10 points!!

sometimes you want to shut off the bleed air but not shut the engine down, right? like if the conditioning unit for the air fails, but there is no risk of engine fire; well, you don't want your pax to burn up but you want to keep flying. or am i thinking the worng thing here?
