§ 35. Mr. DAYasked the Under-Secretary of State for Air whether all the machines used in the Royal Air Force at present are fitted with the slot safety device; and, if not, how many are not so equipped?
§ The UNDER-SECRETARY of STATE for AIR (Sir Philip Sassoon)No, Sir; in the case of certain types of Service aircraft, slots would seriously impair operational efficiency. Otherwise, they are fitted whenever it is advantageous to do so. It is not the practice to insist on slots in current specifications, the stipulated flying characteristics near the stalling speed being obtainable without them. The answer to the last part of the question is that 14 out of 35 types of Service aircraft are not equipped with slots.
§ Mr. DAYCan the right hon. Baronet say how many altogether of the aircraft are fitted with this device?
§ Sir P. SASSOONI could not say without notice.
