Wherever there is no turn an bank indicator, it is advisable to install a bank indicator. This simple instrument is particularly useful in training aircraft. Slip/Skid Size I, No. 1110 Winter Slip/Skid fits in a standard 57 mm (2 ¼") instrument hole.
Size I has exactly the same dimensions as an electric turn and bank indicator installed in the small standard housing. It can be replaced by an electric turn and bank indicator at a later date, without the need for any alterations to the instrument panel
