FLIGHT, MARCH 22, 1934 IMPORTS AND EXPORTS The Editor does not hold himself responsible for opinionsexpressed by correspondents. The names and addresses of the writers, not necessarily for publication, must in all casesaccompany letters intended for insertion in these columns. BRITISH v. AMERICAN AIRLINERS [2917] Being a Canadian, and therefore on the fence between Britain and the U.S.A., I am interested in watch- ing aeronautical developments in both countries. My neutrality takes the form of boosting things British when talking to Americans, and boosting things American when talking to Britons. I take this opportunity of doing a bit of the latter in comparing two aircraft, the D.H.86 and the Lockheed " Electra," both of which have been recently described in FLIGHT. Never have I seen two aircraft so closely comparable in purpose, accommodation, weight, power and modernity. Not only do these machines afford material for a U.S.-British discussion, but also a new answer to the old questions of monoplane v. biplane and wood v. metal construction. In this case we find that the American all-metal mono- plane has the same useful-gross weight ratio as the British wood-and-fabric biplane, and 9 ft. 6 in. less span. The Lockheed's cruising speed is 30-35 m.p.h. higher than the D.H.'s, and its landing speed 9 m.p.h. lower; the maximum speed ranges are 3.41 and 2.36 respectively. (Incidentally, I think a landing speed of 72 m.p.h. should be appalling to Britishers since their standard objection to American aircraft has been their high landing speed.) Reducing the Lockheed's range to the 460 miles of the D.H. and giving it the same allowance for furnishings, radio, etc., we find identical payloads of 1,940 lb., so that their efficiency figures come to 0.320 and 0.272 (ton-miles/horse- power-hour) respectively. Passenger miles per h.p.-hour show 3.30 and 2.81, with 240 1b. allowance for baggage in each case. The Lockheed lags then only in manoeuvrability with engine(s) cut, volume of cabin space, and probably in first cost. The D.H. should be credited with the first two of these points, although the Lockheed is not inadequate, while the difference in first costs will be overcome after five or six years' service when the D.H.'s fabric and plywood has been renewed several times. Incidentally these two machines are intended for use under very similar conditions: the D.H. on the Empire airway from Singapore to Australia, and the Lockheed on Pan-American Airways from Mexico to Buenos Aires. The D.H.86 figures are from official tests, I believe, while the " Electra's " are based on calculation, but the margin is great enough to leave little room for doubt. Finally may I say that I admire the D.H.86, as I do all D.H. aircraft, but only wish to point out that while it is above the average for ships of its type, it has not necessarily " taken a step in front of the rest of the world." C. D. LONG. Toronto, Canada. March 7, 1934. • • • <• The Model Aircraft Club Ax Stag Lane Aerodrome on Saturday, March 24, the Model Aircraft Club is holding, under the patronage of Capt. G. de Havilland, an exhibition of models, photo- graphs, lantern slides, etc. From 11 a.m. till dusk on Sunday, March 25, there will be model flying on the aerodrome. The College of Aeronautical Engineering EACH year sees some improvement, both in the organi- sation or the curriculum of the College of Aeronautical Engineering. The latest prospectus, which may be obtained from Sydney Street, King's Road, Chelsea, contains few deficiencies or redundancies. Although basically similar to those of previous years, the curriculum includes a num- ber of new subjects. The list of Honorary Lecturers includes Mr. A. Nigel Norman, of Airwork, Ltd. (" Aero- drome Development "); Mr. Brian Allen, of Henlys, Ltd. (" Sales and Service "); Mr. R. F. Banks, of the Ethyl Export Corporation (" Fuels "); and Mr. J. D. Titler, of the Airscrew Co., Ltd. (" Airscrews "). Jan.Feb. .. Exports 1933. £ .. 82,963 .. 79,357 1934. £ 255,437 69,623 162,320 325,060 Imports and Re-exports.—From January 1, 1934, con- siderable changes have been made involving re-classifica- tion of a number of articles. Under this re-classification apparently the value of aircraft imports and re-exports have been lumped with imports of locomotives and ships. It is therefore no longer possible to give the figures for aircraft imports or re-exports. * • * * PUBLICATIONS RECEIVED Air Review. Vol. I, No. 1, March, 1934.
