From "La centuria alata" by Italo Balbo: "Precision instruments are of special interest, the main ones being: the compass, the speed indicator, the up and down indicator, and the turn indicator, all in a single bright square, according to the "Nistri-Biseo" system The magnification of the movements of the sensitive devices is obtained optically.The masses of inertia are thus abolished. There is also a Sperry artificial horizon with a gyroscopic system for indicating the longitudinal and transverse trim of the apparatus and a Sperry direction indicator for course control."
