chopjock, I see from your profile that you own and operate a H500 and hold a PPL. I beg of you, please, please take heed of the advice given by the old heads here, SASless, Crab and Thomas Coupling. I'm betting you have no IF experience to speak of, scud running and driving your 500 into a cloud is only going to have one outcome, the exact same as prompted this thread. Get home'itis is a killer, park it and get the thermos and sandwiches out, or take a cab. Your wife/partner and kids will thank you for it.
