Yes. I've converted ex-Vietnam A.F. pilots (Soviet equipment) to western equipment.
They all had great difficulty coming to grips with the western way of depicting/doing things.
Russian AI's do use a ground pointer. Forgot about that in my previous post.
Also the multi-crew philosophy isn't so much 'two pilots act as a safety buffer to each other's errors & can manage alone if necessary', as a case of 'no single crewperson can operate the a/c alone so it takes the whole crew en-masse to defect'. Awkward to arrange when one or more member(s) can be a political 'plant'.
This makes single pilot IFR quite a challenge to a someone only familiar with this Soviet method of operation.
