Thanks much, got a post it on the canopy now, no long duration neg g fun.:doh:

Ok 5k, feet i roll inverted and do an outside loop, at just past ap, both engines flamed out and spool down, i leveled out and was able to get one engine restarted 200 feet off the deck....just before i went into the trees. Grin. So the hog fuel pumps starve at negative g's? Only reason i can see for them both shutting down.

In the simplest terms you are going to use that guage to monitor at a glance and ensure you do not grenade your engine due to detonation or overpressure, adjusted for altitude. Seasoned pilots can do this by sound and rote action in the real deal so it becomes like breathing.
