Quite correct Mr Meagan, it’s called a ‘Departure Alternate’ by my current employer.
I have never had anything to do with NVMC always avoided it like the plague. Some of the most difficult IFR flying is taking off on a moonless night on a country strip with no visible horizon and no lights anywhere (apart from RW lights).
I flew into Porepunkah in the early seventies in a Navajo with Bill Borthwick a State Minister of something when Australian Aircharters had the State Premiers contract. The reason I remember it so well was trying to get out safely with low cloud and rain. (Was one of many scary moments learning the trade in my youth).
Trying it at night in a 182, no thanks.
