Flight investigation of some airworthiness problems of civil boat seaplanes

Abstract

A general investigation has been made into measurement, control and performance problems associated with boat seaplane take-off and initial climb. Particular attention was paid to engine failure during take-off and initial climb, and also to the criteria to be used for defining the minimum speed for control in the air. The aircraft employed was a Solent flying-boat of weight 78,000 lb, powered by four Hercules Mark XIX engines. The general conclusion is that the present methods used for landplanes are also applicable to seaplanes, with certain modifications to meet water-stability requirements and the greater freedom of manoeuvre available with respect to heading and position on the water.
