APRIL 21, 192 I 35 '&" O.A.LENGTH l9'-i" W/A/S AREA 116 -2 MAX. CHORD 4-'Zk" AVI A B.H.(£xpl 35-40 HP. Austro-Ddimkr En (Sine . THE AVIA B.H. (EXP.) 35 H.P. MONOPLANE : General arrangement drawings. —which are comparatively narrow—are constructed of three-ply. The engine is a 4-cylinder 35-40 h.p. Austro-Daimler, mounted in the nose of the fuselage, driving a 6 ft. 6 ins. walnut tractor air-screw. The radiator is mounted in the nose of the fuselage, below the engine, and is fitted with adjustable shutters. Behind the engine is a petrol tank of 13.2 gals, capacity; behind the tank is the passengers' cockpit, followed by the pilot's, in line with the trailing edge. The usual " joy-stick " control is fitted. The landing chassis is of the Morane-Saulnier " M " type, with divided axle, the outer strut members—forming the usual V, viewed from the side—being completely covered in with three-ply. During flight the axle lies enclosed in a three- ply fairing, which really forms a small, narrow lifting plane. Provision is made for the free upward movement of the axle when landing. Rubber shock-absorbers are fitted. During its first trials—carried out by Josef Novak—an engine of only 26 h.p. was fitted, and with the loadings at 31 lbs./h.p. and 7 lbs./sq. ft. a speed of 68 m.p.h. was obtained ,and the climb was 3,300 ft. in 10 mins. Unfortunately, we have no other particulars of this machine's performance withfull power. The stability is said to be remarkably good, in spite of high C.G., and it manoeuvres with great facility, andclimbs quickly. The gliding angle is small, and the get-off and run along the ground on landing are short. The following are the principal characteristics of the A viaB.H. :— Span 35 ft- 5 ins.Chord (max.) .. .. .. 4 ft. i\ ins. Overall length . . . . . . 19 ft. Overall height .. .. .. 6 ft. 8 ins.

R.A.F. and Belgian Decorations THE King has given unrestricted permission for the wearing of the following decorations conferred by the King of the Belgians on officers of the Royal Air Force in recognition of valuable services rendered in connection with the War ;— Order of Leopold Commander.—Air - Commodore Charles Laverock Lambe,C.B., C.M.G., D.S.O., R.A.F. Officer.—Group Captain Cyril Louis Norton Newall, C.M.G.,C.B.E., A.M., R.A.F. Order of the Crown Commander.—Air-Commodore Frederick Crosby Halahan, C.M.G., D.S.O., M.V.O., R.A,F. Officer.—Wing-Commander Lewis Leisler Greig, M.V.O., M.B., R.A.F. Croix de GuerreAir-Commodore Frederick Crosby Halahan, C.M.G., D.S.O., M.V.O., R.A.F. ; Group-Captain Cyril Louis Norton Newall,C.M.G., C.B.E., A.M., R.A.F. The Gordon Bennett Balloon Race SEVEN nations and sixteen competitors are at present inprospect to compete in this international spherical balloon event, to start this year, it is hoped on September 18, fromthe Brussels Exhibition grounds—that date giving a full moon. The trophy, of which Belgium is the present holder,is challenged by three competitors from each of the following members of the F.A.I. : Aero Club of France, A.C. of GreatBritain, A.C. of Italy, and the A.C. of America ; the A.C. of Spain and A.C. of Switzerland are represented by onenominee each. In addition there will be two entrants from Belgium, the holding club. Another Avro Baby '' Record '' JUST by way of showing that his flight from London to Turin non-stop on the Avro Baby was not merely a lucky flight made under favourable circumstances, Mr. Bert Hinkler made another wonderful flight in Australia on April 11, when he flew the same machine from Sydney to Bundaberg, his home town, in a non-stop flight. The distance is approximately 800 miles, and was covered in under nine hours. The fuel consumed on the flight was about 22 gala. of petrol, so that the machine averaged over 35 miles to the gal., which is distinctly good. The Avro Baby used was the same as that on which Hinkler flew from London to Turin, as was also the 35 h.p. Green engine. This engine, it may be recalled, is ten years old, having originally been fitted in an early Avro machine at Brooklands in 1911. The same machine and engine, piloted by Capt. Hamersley. won the sealed handicap of the Aerial Derby in 1919, and on it Hinkler secured second place in last year's Aerial Derby. It would be difficult to imagine anything which would better demonstrate the capabilities of the Avro Baby-Green combination than this second wonderful flight of Hinkler's. and one hopes that he may long continue such demonstration flights in his native land, to the advancement of the industry and, incidentally and deservedly, to the good of the Houses of Avro and Green. No. 2 Aircraft Dep6t Officers' Association THE next dinner will be held on Thursday, May 5, at 6.30 p.m., at " The Cock Tavern," 22, Fleet Street, E.C., morning dress. The Association is visiting the R.A.F. Depot at Milton, Steventon, Berks, on Saturday, June 25. All applications to be sent to the Hon. Sec, J. D. Fairbairn, " Hillsboro," Cromwell Avenue, Bromley, Kent. 272
