Something that always intrigues me, this C310 has been on the register in Australia since 1978, but in 2025 we still have the standby AH down on RHS side of the panel.
Back in the day DCA would have been involved in getting it on the register, how many pilots would flown the thing, numerous IFR renewals would have been conducted in it, surely somebody would have said this standby AH is in the wrong position, or RHS side of the panel needs to be tidied up?
An AH failure on night rotation at Alice Springs, that standby AH is not really going to be in your scan is it? Not to mention the high quality instrument light in a nearly fifty year old twin!
