Thank you,
Roffa - I would be surprised if altimeter-related errors were not a significant causal factor in level busts - however, I see the notes say that
"80% of the errors occur when the aircraft is in the climb, is above the transition altitude/level and the standard pressure setting isn’t set."
Unfortunately I can see no breakdown of the remaining 20%, and therefore it is difficult to see any clear relevance to our particular discussion.
