Question for all you ex-PNG expats out there.....
Was in PNG a while back looking for a job and spent a while hanging out with a few different companies and observing from the RH seat.
The thing that amazed me was that the majority of time was spent flying round in about 1/10 of what's classified VMC in OZ, down valleys and over ridges which sepnd 90% of their time shrouded in cloud, in areas where the terrain a mile ahead of you looks the same as the terrain a mile behind you and the odds of getting a 'fix' aren't even worth calculating.
Was all fairly do-able given that all the boys up there now have GPS, but what i'm wondering is how the hell did you boys navigate into back country stirps with marginal WX back in the 70's? I imagine it would have put a whole new definition on the term 'dead reckoning'?
