§ Mr. van Straubenzeeasked the Minister of Aviation what further trials are in prospect as to the effect of slush on the rate of performance of aircraft; and whether an Elizabethan will be included in the trials, having in mind the accident which took place at Munich in 1958.
§ Mr. MartenWork has been in hand for some time to devise a system of measuring the effect of slush on take off, and it is proposed to conduct a series of trials on a number of individual types of aircraft, including the Elizabethan. These trials must be fitted in with other work, and the availability of aircraft. It is hoped to conduct trials with the Elizabethan in July of this year.
