Performance and Handling Trials


               Although a long time has elapsed since the introduction of the Merlin XX engine into the Hurricane, and although several reports have already been issued on the results of tests made of Hurricane IIís, this report deals with the results of tests made on the aeroplane as a type and is designed to be used as a basis for comparative results either already obtained or to be obtained in the future.
