That only applies if you have and can maintain visual reference to the ground. We're talking here about what do you do once having lost visual reference? That appears to be what happened here. The APNG flight could not land at Kokoda due to the weather (otherwise they would have landed), and they probably remained in the weather until the point of impact(otherwise they wouldn't have flown into the mountain)
You
DO NOT know that. I can tell you what they were NOT doing and that is tooling along in IMC and then whacked into 'a mountain' sticking up in front of them.
I do have an idea what
MIGHT have happened because it has happened to me - I
HAVE seen
EXACTLY what they saw in their last seconds but I got away with it. THAT is why I WILL NOT be drawn into any more of your inane posts and why
I won't do anything other than help people to understand the challenges they faced.
