Although FFF makes several very good points, and God knows we've all relied on the 'experienced guy' on occasion, unfortunately after an accident its the letter of the law not the usual practice at FTO's that counts. The younger guy here was P1 - end of story and incidentally, I suspect the 'experienced' one in this case wasn't as 'experienced' as the P1 thought.
Notwithstanding, there are clearly many and various other circumstances surrounding this extremely sad case and recrimination is now mostly pointless but I wanted to chuck in my 2p on a specific aspect which just might help someone somewhere.
The main thing I have to add is that training in the discipline of command is largely missing from PPL training. It was certainly missing from mine! However, luckily for me after about 5 minutes in the RAF system that soon changed.
I dont mind telling anyone that there are times without number I have wondered quite literally how I survived those first couple of hundred hours before that. I try not to be the 'old fart' these days but that long forgotton trait of 'Captaincy' has saved many lives when light aircraft were not hi-tech, glass screen, gps driven pretend airliners.
PPL Instructors should spend at least some time (and I know some do) talking about how once a PPL is in your pocket, you are in command, even if you have a 10,000 hour ATPL/IR TRE..TRI skygod... etc etc etc sitting alongside you, if its your P1 its your decision.... and yes sometimes its difficult to voice your opinion but a quick read of this AAIB report should hammer the point home!
Also point out to trainees that the airlines themsleves have a serious and growing problem with the 'gradient' in the cockpit especially with younger fATPLs and they include it in their courses now and the crusty old farts are having to learn it too.
Anyway, as always condolences to all involved and as someone has already said this report should be required reading for all!
