    Watched a programme where the difference between Western and Soviet artificial horizons may have caused crashes.

    In Western aircraft the horizon moves and the wings don't. In soviet aircraft the wings move and the horizon doesn't.

    So a right turn in a western indicator can look like a left turn in a Soviet indicator.

    It is said that in a full blown emergency, an old school Russian pilot falls back on his training and flies a Tupelov again instead of an Airbus and end up in the ground because his training is telling him what he is seeing.

    Former WarPac and other Soviet allies who now fly Western jets have to be re-trained and un-trained to fly western artificial hirizons.

    I'd like to see documentation of crashes attributed to this. Many former east bloc aircraft operated in the US still have the old soviet style attitude indicator and their owners seem not to have issues with them, although there have been some who removed this and opted for a western system. Additionally some of these aircraft have AC inverters that power these instruments and they are heavy and bulky, another reason for their removal.
