(3) The weight of power plant also trends downward from 30 per cent, for small to 20 per cent, for large machines. (4) The weight light for machines from the smallest to the very maximum sizes has to-day a lower limit at about 53 per cent. (5) For large flying boats and large aeroplanes the weight light is about the same. (6) The structural weight is\high for low-powered machines and low for high-powered machines, and in general the best weight carriers show about 18 lbs. per horse-power. Examination for Aviation Ground Engineers THE Air Ministry announces :— Arrangements have been made to hold examinations for candidates desiring to become certified ground engineers (aircraft or engines), under Section 4 of the Air Navigation Directions, 1019, at the following centres during July and August:— London, July 7, August 4, July 21, August 18 ; Bristol, July 27 ; Birmingham, July 28 ; Manchester, July 29 ; Leeds, August 24 ; Newcastle, August 25 ; Glasgow, August 26. A candidate may apply to be examined as a Ground Engineer to overhaul and inspect all flying machines and/or engines, or for the examination of any named type or types of flying machine or engine. The examinations which may be partly written, partly oral and partly practical, will be based on the syllabi outlined in Air Ministry communique No. 499 issued on March 5. Candidates desiring to be examined can obtain application forms from the Secretary, Air Ministry, London, W.C. 2, and should submit their completed forms of applications, accompanied by a fee of 5s., at least seven days prior to the date on which examination is desired. Candidates should also state at which of the above places they wish to be examined. Aerial Mail Transport in India, etc. ADVICES just to hand from Calcutta report that the Indian Government is prepared to consider contracts of fifteen years' duration with private firms, for the establishment of effective Aerial Mail Transport Services for India, Burma and Ceylon. Aerodromes are to be erected for the purpose, the main establishment connected with the Royal Flying Corps being situated at Bangalore. As an initial step in the encouragement of Indian aviation, the British Government has recently presented to the Indian Administration 100 aeroplanes of which four are destined for Burma. A certain number are to be placed in the care of the Indian Princes for special employment in the)jr own territories. A native School of Instruction is being established, and the prediction has already been made that a complete Indian Aerial Service will be in existence before the end of 1921. At the present time, Calcutta is the aviation centre for India, and is likely to remain so owing to its geographical position. A Company has already been registered there with a capital of 15,000,000 rupees under the title of Handley Page Indo-Burmese Trans- (7) Similarly, the structural weight is high for low wing loading and vice versa. (8) The wing loading is found to be greater for the larger machines, reaching a maximum of nearly 12 lbs. per sq. ft. for the large flying boats. (9) It appears that all the evidence from past practice indicates that large flying boats can safely be given a higher wing loading and a higher landing speed than land aeroplanes, and, hence, have a distinct advantage as weight carriers for commercial purposes. (To be Continued) <;> <§> port, Ltd., for the purpose of undertaking comparatively short passenger and freight services pending the establishment of permanent long distance services to suit the commercial needs of the country. An aeroplane works, a school of instruction, and an hotel form part of the objects of the Company. To Our Readers As we continually receive complaints from readers that they experience difficulty in obtaining their copy of FLIGHT promptly each week, we draw their attention to the sub- scription form which is printed on page iii of the current issue. If this is sent, accompanied by the appropriate remittance, to the publishing offices, 36, Great Queen Street, W.C., it will ensure FLIGHT being received regularly each week upon the day of publication. Art and the Air AN exhibition of aircraft paintings, by Mr. Geoffrey Watson, is to be held at the Brook Street Art Gallery, 14, Brook Street, New Bond Street, for two weeks from July 7. The exhibition, which is under the patronage of H.R.H. the Duke of York, K.G., and in aid of the R.A.F. Memorial Fund, to which the whole of the proceeds will be given, will be opened informally on the 7th by the Right Hon. Lord Hugh Cecil, M.P. (Chairman of the Memorial Fund), at 12 noon. The pictures number about fifty, and for the main part depict incidents of the air war, but a number of peace aviation pictures will also be shown. Admission to the Gallery will be is. 3d., and the Exhibition will be open daily from 10 a.m. to 6 p.m., and on Saturday from 10 a.m. to 1 p.m., until July 21. Aerial Services in Brazil Now that the Brazilian Government has definitely signed a contract with the Handley Page Co., no doubt the services will soon start. The first stage will be from Rio de Janeiro to San Paulo, the first step to linking up by air with Buenos Aires and ultimately with every city of any importance in Brazil, Uruguay and Argentina. At Rio, the headquarters will be on the Ilha do Gouvernador, where there will be a flying school. From San Paulo, will be ex- tended to Florianopolis, Porto Alegre, Pelotas, Montevideo and so to Buenos Aires. It is anticipated that the journey from Rio to Buenos Aires will take 20 hours against the 6 to 8 days now required by steamer. , -• - . 695
