K52
They were in control at waypoint A which was, I suggest, already too close in to climb to IMC height and therefore it is evident that they were going to stay low and turn up the coast VFR in the all-too-common conditions.
So the question still stands - what was the practice in this situation? ie the Mk1 eyeball or TACAN. Or was it always just left up to the crews? - I rather think that this situation was too common on this route for this to have been the case.
Anyone reading this thread or the transcripts of the inquiries would probably think that this particular crew was doing its own thing on some special route in unusual conditions - why the fear of discussing what was the usual practice? Why was this not the starting point for the inquiries?
