SEPTEMBER II, 1947 CURRENT DESIGNS FOR CIVIL AND MILITARY USES: PRODUCTS OF 22 FIRMS AT the Society of British Aircraft Constructors'Display and Exhibition at Radlett this year manu-facturers in this country will show, and in most cases demonstrate, something of every type and class of aircraft. As the production tempo of military aircraft continues to slow down, our efforts to produce commercial transports of all types and sizes gathers impetus. In the short space of two years, in spite of the many difficulties, more than a dozen passenger and freight aircraft, varying in size from light twins to large fours, have been designed, built and flown successfully. Perhaps more important are Airspeed ConsulT HE Consul is the mostmodern of a long line of Airspeed models, startingwith the Envoy in 1934. In the same line the Oxfordwas used for training during the war, and long experiencehas resulted in this efficient civil aircraft. The Consul isbeing used extensively by charter companies for pas-senger and freight carrying, and could be convenientlyconverted for ambulance or other specialised work.

The Ambassador, one of the products of Airspeed, Ltd., Christ-church, Hants, is suitable for development with reciprocating engines or airscrewturbines. The type of airscrew turbines to be fitted has not been decided, butfour Naiads or two Proteus are being considered. Design will allow the finalversion to fly at an all-up weight of 52,500 lb. The Ambassador will complywith I.C.A.O. safety requirements. the designs, very advanced in conception and truly repre-sentative of post-war British thought, which are now taking form in many parts of the country. In the following review of the British aircraft now flying,the summaries of their principal characteristics are classified under the headings : civil, projected and research, andmilitary, in that order. At present it may be said that the interim civil types arecarrying the burden for the British airlines and the charter companies, but gradually the true post war transports aretaking their place, particularly in the light-twin categories. Auster AutocratM ANUFACTURED byAuster Aircraft, Ltd., of Rearsby, Leicestershire,the Autocrat is used ex- tensively by private ownersand clubs and is a develop- ment of the earlier militaryaircraft. A two-seater version, powered by a Con-tinental engine and weighing slightly less, is known as theArrow. This version has a cruising speed of about87 m.p.h. and a maximum speed of 98 m.p.h. Bothmodels are economical all-purpose light aircraft and many are being operated indifferent parts of the world, in some instances under difficult conditions.
