151:. One difference from a typical (Segelflugzeubau Kassel) Zögling was that the BS.16's ailerons were increased in length from 40% to nearly 60% of the span. The wings were braced with a pair of struts which ran separately from the lower fuselage frame, slightly diverging, to the wing spars. These removed the need for many of the wing bracing wires and for the triangular pylon of the Zögling to which they were attached.

159:. The forward vertical supported the wing at its front spar and the two diagonals met on the rear one. The lower frame extended forwards, with the pilot's seat projecting either side of it immediately ahead of the forward vertical frame. Underneath it, a curved skid was mounted and faired in, forming a long, deep, narrow box, reaching aft to the rear vertical frame. From the

rearwards the upper frame member was split into two, running parallel to each other and cross braced in the horizontal plane. This provided extra stiffness against sideways flexing and further reduced the wire bracing. Aft of the second vertical member the lower frame sloped upwards, meeting the

The forward fuselage frame consisted of two, parallel horizontal members, one above the other. They were connected by a vertical pair of members and two diagonal ones, attached at two points on the lower frame and three on the upper. The rear vertical member was lighter than the forward three

Despite its seemingly late type number, the BS.16 was one of the first aircraft designed by
Camillo Silva after joining the company set up by Vittorio Bonomi in about 1930. Like many primary gliders of the period, its design was strongly influenced by the popular
183:, which was hinged on the extreme frame and was rectangular apart from a cropped under edge. The BS.16 sat with its tail well clear of the ground, so no tail bumper was required, though there was a short aft horizontal extension of the main skid.
124:, the wing and fuselage bracing and the aileron area, though comparisons are not straightforward as there were many Zögling variants, all different in detail.

The
Allievo Bonomi was well received by Italian gliding clubs, who used it to take novice pilots to their A certificate. More than sixty were sold.
