My contention was "Run Dry" should be exactly that..."Dry"!
So by this You mean that the FAR29 goal of run dry is that it has to be
dry, and not the ability to continue to fly safe if all MGB oil leaves the MGB ?
Then loss of one engine literally meaning it has to fall of the A/C ?
Yes, I know...the term is 'One Engine Inoperative'. But also, in FAR29(29.927) I don't think they use the term "Run Dry".
By the way, why does it matter how the manufacturer is keeping A/C able to safe continue to fly ?
