SEPTEMBER 12TH, 1946 FLIGHT FOR AIRLINE, CHARTER AND PRIVATE OWNER much to make unsubsidized flying not only possible butprofitable. Nevertheless, the Dove fulfils much the same requirements, as well as being entirely up to date in bothdesign and equipment. It is an all-metal, 8-n-passenger tricycle type, intended primarily for operation on tributaryroutes. Apart from the provision of maximum passenger comfort within the size limitations imposed and of an ade-quate modern all-round performance, the design has allowed for simple and economical maintenance. The Dovehas an all-up weight of 8,500 lb, a maximum speed of 222 m.p.h., and a normal cruising speed (at 50 per cent^take-off power and 5,000ft) of 155 m.p.h.—at which speed total fuel consumption is 22 galls /hr. The maximumveak-mixture cruising speed is 200 m.p.h. at 8,500ft. It has a rateof climb on one engine of 230ft /min, and the aircraft complies, of course,with A.R.B. "asymmetric" take-off requirements. In addition to thevarious D.H. aircraft being flown at Radlett there will also be exhibited amock-up cabin for the Dove as laid out for private-owner travel. General Aircraft WHILE the power-assisted Hamilcar X, which will be demon- strated at Radlett with military load and a Halifax tug, also has useful civil applications, General Aircraft's static ^ exhibit will include a scale model of f the Universal transport which is now maximum of 63 passengers; and the pressurized Mark III,which is due to be powered with Bristol Theseus airscrew- turbines, which will carry much the same passenger load asthe II, but at a cruising speed of 355 m.p.h. For the moment, the Hercules-engined Hermes I is, however, ofmajor importance. This has an all-up weight of 75,000 lb and an economical cruising speed of more than 200 m.p.h.at 10,000ft. With full tanks the Mark I has a still-air range of 4,720 miles, or, with reduced fuel supply, a maxi-mum payload of 16,000 lb—which can include 50 passengers. For more immediate " interim " use there is the Halton—a civil transport version of the Halifax C.VIII. Twelve Above is one of the latest versionsof the Percival Proctor—the Mk. V - -which has a cruising speed of140 m.p.h. The Miles M.38 Mes- senger (below) is a three-four-seater private-owner type with safe and easv flying characteristics. Originally designed for economical freight-carrying work, the Miles Aerovan can also be equipped as a 10-seater " air coach " for short-range journeys. g developed by the company. In this particular ver- it is arranged to accommodate 90 passengers, and its 1-up weight is expected to be 87,300 lb. This interesting and practical large aircraft will be powered by four Bristol Hercules, and is a high-wing type with a tricycle under- carriage in which only the front wheel group is retractable. The Universal transport is intended to fill the future need for a comparatively short-range utilitarian load-carrier, and will have a cruising speed of 170 m.p.h. Handley-Page THE first civil aircraft to be built by the company since•*- 1930, the Handley-Page Hermes is being produced in three different forms. The Mark I, in both unpressurizedand pressurized versions ; the Mark II, which will be pres- surized and will have a longer fuselage to accommodate a of this type are now in service with B.O.A.C. The Haltonis a ten-passenger aircraft with, in addition, both the load- carrying and space capacity for 8,000 lb of baggage, freightor mail, which is carried in the modified bomb bay. The Halton's economical cruising speed is 210 m.p.h. atIS,oooft, and its maximum still-air range, with normal tankage, is 2,420 miles. Miles TTEADED by the Marathon, which was designed to-*•-*- Braba.zon VA requirements, Miles Aircraft show a wide range of civil types. The development tests of the four-engined, medium-range, medium-capacity Marathon have been_under way for some time. With its four Gipsy Queenengines, the Marathon has an economical cruising speed of 175-210 m.p.h. and a payload of 3,600 lb over a still-air
