THE trend of development in size of seaplane and landplane designs is established from current modern American designs. The tell-tale charts of their characteristics and mainly of useful load-range-gross load relations are given. It is assumed that a cruising speed above 200 mph for transatlantic travel is a necessity and deduced that, although seaplane design would have to go as far as 100-passenger, 100-ton size in order to fulfill the requirements, the landplane of about half this size would do.
The characteristics, weight, performance estimates, and the general outline with the operationcost figures of a transatlantic landplane project for non-stop New York-Paris flight are presented. It is believed that the bright prospects of this solution are made possible by systematic weight and drag savings, these being facilitated by the elimination of the otherwise necessarily big and heavy fuselage and by the advantageous wing arrangement, where comfortable accommodations for 48 passengers are provided and where the great gasoline load is distributed along the span. The project TA-2 is supplemented for comparative purposes with the project TA-1, differing only in fuel capacity.
