VP - that's great information - so EBCAU will govern Nf then so even if DECU's 'flip out' the basic EBCAU should stop overspeed ... ? and so T/R might not overspeed if that all works ...
as an aside (whilst we have an expert on the line) people run helis up without blades sometimes - does DECU have a problem with this ? Is there an issue with feedback/resonance/oscillation ? Is it an 'ok' procedure to run with out blades?
