§ 12. Mr. CHORLTONasked the Under-Secretary of State for Air whether any application of heavy-oil aero-engines has been or is immediately contemplated for large flying boats to enable, by reason of their higher economy, the possibility of longer flights being made?
§ The UNDER-SECRETARY of STATE for AIR (Sir Philip Sassoon)Yes, Sir; a test is being arranged.
§ 13. Mr. CHORLTONasked the Under-Secretary of State for Air whether he will consider special attention being given to the use of high-economy heavy-oil aero-engines, using fuel of low cost, to civil mail aeroplanes to enable the postal air-service to be greatly and economically increased?
§ Sir P. SASSOONSpecial attention is being given to the development of such engines; their application to mail carrying aircraft will no doubt follow when their efficiency, reliability and economy in operation have been proved.
§ Mr. CHORLTONWhen are we to receive a little more detailed information of the progress which is being made?
§ Sir P. SASSOONThe hon. Gentleman knows that progress is very slow.
§ 14. Mr. CHORLTONasked the Under-Secretary of State for Air the number of types of aero-engines using heavy oil as a fuel that are now available for installation or already in use in the Royal Air Force or civil aircraft?
§ Sir P. SASSOONThe answer is that two such types of aero-engines are available, but they must still be regarded as being in the experimental stage.
