Phil77, perhaps not clear enough but I was referring to riff_raff's post,
The MRGB in the S-92, like all other FAA certified rotorcraft MRGB's, is qualified for operating in a 30 minute loss of lube condition while maintaining power levels sufficient for level flight. Thus the pilot has a 30 minute period after the HUMS gives an indication of loss of lube circuit pressure, in which to continue at level flight and/or perform an emergency landing. So that should not be a concern to you.
The fact is the 92 does not have a 30 minute capability as suggested by riff_raff, and as I said in my previous post he can not be blamed for having that view as it has been propagated erroneously by the professional aviation press as if it were fact. As I said, search for HeliComparator's posts on the subject.
HC, why are you leaving the job to this amateur, you're the professional?
