It may be taken generally that the wider the body the greater the weight, for the struts have not only to be made longer but also of greater overall section. The practice in this country is to keep the longerons parallel to the centre line on plan, as far as the rear cockpit, tapering from that point to the stern post in a straight or slightly curved line, as [Fig. 71].

This simplifies the fittings, the sockets for the centre plane struts are in line, and the different lengths of fuselage struts necessary reduced to a minimum.
