Thanks' TowerDog . . . . .However to ExRAFboy, - that is all well and good info, but the hypothetical question of post #221 was - with respective boost pumps on "off" (and all crossfeeds otherwise normal for t/o), will the outboard engines run a 8,600ft altitude t/o roll and departure?
I know that they will when from sea level, because years ago (although it was daylight), bonehead me did just that!
The fuel pressure lights would glow, but they would glow dim (if dim selected) and if everyone had their eyes up front, they could be missed.
