Not trying to be smart or cute, but how does someone first on scene know to look up this manual? Wouldn't most rescue personnel be hard pressed knowing it is a Cirrus and not just a "Cessna"?
That is a very good point FTS. Our local fire brigade has been briefed on the Cirrus in particular, however the point would be that you should treat ALL aircraft as live in terms of a BRS as they could be fitted to many aircraft, RA-Aus in particular as well as even Trikes.
If you're fire brigade is from a non-aviation area nowhere near an aerodrome, the potential is there for them to go barreling on in and have some issues. Some might say that would be unlikely, however in many of these areas you're talking about CFA volunteers whom may not be aware of such equipment.
It's a good topic of discussion.
