Would I be correct in saying that a Russian attitude indicator would depict a movable aircraft symbol as opposed to the fixed aircraft on a Western AI?
Only Russian aircraft I have flown is the Yak 18T with a Western AI (speed indications in kilometres an hour still confound me at times though). It is so easy to revert to type when tired or distracted.
Lack of type training and experience as well as an approach in IMC plus the communication overhead and it easy to comprehend why a pilot might revert to a previously learned mode of thinking.
The question of inebriation doesn't even bear countenancing.
