Any comments on the likely success of operation when not inverted?
Having seen the way these heads work in sprinkler systems I'd be
surprised if a satisfactory result came from horizontal mounting. Would
it deploy fully on its side?

It would be less effective on its side. The AFFF would still prevent
fire developing in fuel pools where it had coverage but if the engine
room floor has strakes then some area may not be covered allowing fire
to develop.

I still think it would only half deploy if used on its side (pressure
lost without expelling liquid once fluid dropped below the outlet).
