Experiments in Lateral Control: An Account of Tests with Autoslots and Interceptor and Spoiling Devices on the same Aircraft

WING tip automatic slots have proved an effective device for providing increased lateral stability at the stall and many service aircraft of the two seater and larger types have been fitted with them. In the case of single seater fighter aircraft, where manoeuvrability is of primary importance, it is desirable that adequate control at the stall should also be provided and the plain automatic slot does not, in general, supply this need. Certain aircraft fitted with the interconnected slot and aileron type control have shown satisfactory control characteristics at the stall but little or no increase in stability.
