Convertible aircraft. Fairey Aviation Co. Ltd. Application, April 14 1948. An aircraft for carrying freight is convertible for other purposes, such as passenger-carrying, by remov ing the floor from equally spaced transverse supports 105 and replacing it by a series of standard-sized panels 106 each provided with apertures 118 spaced at standard intervals for the attachment of fittings such as seats 119 and tables 123. The edges of the panels are rebated and apertures 109 provided at the corners to register with apertures 111 in the cross members 105, for the reception of quick-release pins, hinged flaps 110 being fitted to close the openings. Similar pins are inserted into the openings 118 to secure the seats and tables in position, those openings not in use being closed by rubber plugs. Other fittings such as a steward's galley or bar, wardrobes or lockers may be secured in a similar manner. June 1954 205
