HC,
Lets look at progress: the S61 had a system that gave you two hours at Vy. The new regulations give you 30mins at Vy. I don't call that progress. Perhaps the regulations should have been less concerned with dry running and more with having a level of redundency in MGB lube systems which might get you home/safe landing site. 30 mins won't get you anywhere except wet most of the time offshore.
