What he’s saying is that at the initiation of flow to the booster the main air bleed acts like an emulsion bleed and starts the mains sooner and makes the fuel curve slightly richer at start up before the MAB makes the fuel curve tilt leaner at high air flows.
Thats why I’ve been saying pressure differential matters, the area of the jet/bleed matter and even the booster makes a difference.
And as I’ve said, just because a bleed exhibits a certain characteristic at high air flows doesn’t mean it has that same characteristic at low flows.
And the guy waving the banner the highest says that’s NOT what Yeti and Shrinker are saying. I can’t ask Bruce (Shrinker) because he has passed but I can ask Yeti. And that’s exactly what he says and what he writes.
