Both pilots in VOR mode and nobody with MAP. Inexperienced F/O, steep cockpit gradient, dark night, early turn. Lots of little flags popping up. Another one is the fact the Captain had flown Russian equipment. I can never get my head around Russian ADI's. Totally arse up in my opinion.
To lose it so quickly seems a little strange especially with no signs of a recovery as the nose goes down.
Thanks 'Centaurus' all good information to reflect on.
