242 " Flight " photograph. The Hydromatic airscrew on one of the Perseus engines of the Flamingo. and 8,200ft. (2,499 m-) f°r starboard and port engines respectively, the performance on each being slightly different. Rates of climb at sea level on take-off power are 230 and 210ft. /min. (1,17 and 1,07 m./sec.) respectively. The rate of climb at sea level on two engines at take- off power is impressive, being 1,470ft./min. 7,47 m./sec.); on climbing power it is 1,010ft./min. (5,13 m./sec). Absolute ceiling on continuous emergency power is 22,200ft. (6,771 m.) and service ceiling 20,900ft. (6,374 m.). Fuel tanks for 402 gals. (1,827 litres) are provided and an oil capacity of 24 gals. (109 litres). This gives a still air range of 1,210 miles at 65 per cent., and 1,345 at 50 per cent, of continuous emergency power.

Air traffic figures for the services to and from Ireland, in the Western Scottish areas and to Paris all tend to show growth despite the war. This tendency is also show- ing in particular directions. With the opening of the holiday season at Easter, the Workers' Travel Association has an- nounced plans to utilise air travel to Jersey and the Scillies. It is the first time that air travel to Jersey has been arranged by this organisation, and prices are now quoted to include accommodation, rail travel London-Shoreham and London- Penzance respectively, and thence by air. Air Mail Summary TV/TAJOR TRYON'S answer to a question in the House of 1VJL Commons recently gives a useful summary of the air mail services which are at present available by British and other airlines. Daily services go to France, Belgium and Holland and letters for Denmark, Norway, Sweden, Finland, Latvia and the U.S.S.R. are carried onward from Holland. Air mail for other European countries only goes by air to Paris and thence by surface. The time for transmission to Paris (excluding collection, censorship and delivery) is up to 1 day, with 3 and 4 days for Stockholm, Moscow and Rome respectively. On the Indian, Hong Kong and Australian routes there are two services each week with scheduled times of 6 days to India, 8 days to Malaya and Hong Kong, and 12 days to Australia. West and South Africa have one service weekly, taking 5 or 7 days to East Africa and 7 to West and South Africa. Pan American run the Lisbon-New York route twice each week and transmission time might be as low as 3 or 4 days. But weather has put the average up to 14 lately. There is a French service weekly from Marseilles to South America, and London to Rio dc Janeiro. Bupnos Aires and Santiago under the best conditions should take 4, 5 and 6 days respectively. An alternative route to South America is from Lisbon to New York, thence south by the airlines in America. It was stated that air mail received priority of censorship. New Airline Alma-AtaH ami TDEGULAR air communications have been opened between J->- Alma-Ata (Kazakhstan) and Urumchi and Hami (Western China). The new air service, which is a weekly one in each direction, is being run by the Soviet-Chinese Aviation Com- pany '' Hamiata,'' formed by the Soviet Civil Aviation Fleet and the Ministry of Communications of the Chinese Republic. These little-known places are situated in the heart of Asia. Alma-Ata is due south from Lake Balkash while Urumchi and Hami are west from Alma-Ata. The route mileage is very roughly 800 "Golden Era" of D.D.L THE Danish airline company continues to make a thoroughjob of internal aviation. On February 21 it set up a new record by carrying 513 passengers, 29 tons of mail and 11 tons of air freight OR the two services from Copenhagen to Funen and Northern Jutland. The company practically withdrew from the international business and devoted all its flying material to the task of making up for the shortcomings of the railways and shipping. The company's two new Condors are scurrying as fast as they can between Copenhagen and Aalborg, making seven round trips a day each. In addition, a distress call has been received from the county council of Bornholm, asking for the immediate opening of a special service iron) Copenhagen to Ronne, since the shipping companies at the end of a long fight against ice and minefields have capitulated. The "foreign business" at Kastrup is largely being handled by the Swedes, Germans and Dutch, and all machines are booked full. Passenger traffic in and out of Kastrup runs into some 700 persons a day, in addition to heavy cousign' ments of air mail and air freight.
