ROYAL AERONAUTICAL SOCIETY NOTICES ARRANGEMENTS have been made with the Air Ministry to publish extracts, from the scientific press of the world, of articles on aeronautics and its allied sciences. These extracts, which will be published as issued by the Air Ministry in the " Journal of the Royal Aeronautical Society," will prove of inestimable value to all those who are interested in the technical progress of aeronautics throughout the world. A very wide field is being covered, and the full sources of information are given in every case, so that those who are interested can obtain copies of the publication from which an abstract has been made. Among the subjects covered in the first of these extracts may be noted : Fuels, and their Characteristics ; Lubricants and Lubricating Systems ; Light Alloys in Aircraft Engines ; Supercharging ; Cooling ; Light Alloys generally ; Dopes ; Paints and Varnishes ; Fluid Motion ; Wing Design ; Wire- less, Armament; and Airship Design. Informal Discussion.—On January 18, at 6 p.m., Mr. A. H. K. Fedden will open an important informal discussion on " Oil Cooling." This discussion will take place in the Library of the Society. No tickets of admission are required. The chair will be taken by the Master of Sempill, Chairman of the Society.—J. LAURENCE PRITCHARD, Secretary. m mm m NEW YEAR PROMOTIONS IN THE R.A.F.]] AMONGST the New Year promotions in the R.A.F.—a full list of which will be found on p. 7—perhaps the most interesting is the promotion of Air Chief-Marshal Sir Hugh Trenchard, D.S.O., Chief of the Air Staff, to the rank of Marshal of the Royal Air Force. This rank, which is the highest in the R.A.F., and is the equivalent of Admiral of the Fleet in the Navy and Field-Marshal in the Army, was created in 1919 when the R.A.F. titles were reorganised. Sir Hugh Trenchard is the first officer to hold this rank It may be of interest to note here that Sir Hugh—disrespect- fully but affectionately known in the Service as " Boom "— entered the Army in 1893 and learnt to fly in 1912, obtaining his " ticket" on'the Sopwith School Farman at Brooklands on August 13 that year. In 1913 he was Assistant Comman- dant of the Central Flying School, R.F.C., and Commandant in 1914. He was in command of the First Wing of the R.F.C. in France at the commencement of the Great War, and later G.O.C., R.F.C. in the Field, with the rank of Maj.- Gen. In 1918 he became Chief of Air Staff and undertook the forming of the Royal Air Force on the amalgamation of the R.F.C. and R.N.A.S., and later organised the R.A.F. on a peace-time basis. m m m. & Gloster Aircraft's New London Office WILL our readers please note that the Gloster Aircraft Co., Ltd., have changed their London office, and have moved from 49, Rathbone Place to 5, Graf ton Street, Bond Street, W. Their telephone number is now Regent 7355-6 ; telegrams " Glosaircra," London. Hawker " Danecock's " Altitude Record NEWS has just been received from Denmark to the effect that the Hawker " Danecock " machines of the Royal Danish Naval Air Service—several of which were supplied a short while back by the H. G. Hawker Engineering Co., Ltd.—have set up a new altitude record for Scandinavia. The flight was carried out under service conditions with full load, the pilots being from the Royal Danish Naval Air Service. m . m m M REARRANGEMENT OF FORECAST DISTRICTSTHE Air Ministry announces that the Meteorological Office has decided to rearrange the districts into which the British Isles are divided for forecastpurposes from January 1, 1927. The changes affect Scotland and the Isle of Man. In the past the mainland of Scotland has been divided into threedistricts only, the east, southwest and northwest. Weather conditions differ so widely over a mountainous country like Scotland, that these three districtshave been found insufficient, and it has been decided to double the number, dividing the mainland into six districts in place of three. On the other hand,the Hebrides and the Isle of Man will no longer form separate districts, the Hebrides being grouped with N.W. Scotland and the Isle of Man with S.W.Scotland. The Orkney and Shetland Islands will remain, as hitherto, a separate district. The new districts will be as follows ••—District 11—S.E. Scotland.—Extends on the East Coast from Berwick-on- Tweed to Montrose. Includes the following counties :—Berwick, Roxburgh,Selkirk, Peebles, Haddington, Edinburgh, Liulithgow, Clackmannan, Kinross, - Fife, Forfar.District 12—S.W. Scotland.—Extends on the West Coast from the Solway Firth to Loch Long. Includes the Isle of Man and the following counties :—Dumfries, Kircudbright, Wigtown, Ayr, Lanark, Renfrew, Dumbarton, Stirling.District 13 (A)—W. Scotland.—Extends on the West Coast from Loch Long to Loch Shiel. Includes Argyll and Bute. JANUARY 6, 1927 District 13 (B)—N.W. Scotland.—Extends on the West Coast from LochShiel to Cape Wrath. Includes the western parts of the counties"of Inverness, Ross and Sutherland west of a line through Rannoch Station, Fort AugustusBeauly, Lairg and Melvich. Also the Hebrides. District 14—Mid Scotland.—Perth.District 15—N.E. Scotland.—Extends on the East Coast from Moutrose to Duncansby Head. Includes the counties of Kincardine, Aberdeen, Banff,Elgin, Nairn and the eastern parts of Inverness, Ross and Sutherland. Also Caithness. District 16— Orkneys and Shetlands.—Under;this redistribution, Edinburghwill remain in district 11 and Glasgow in district 12. An important change is made in the far north, where the eastern and western parts of the countiesof Inverness, Ross .and Cromarty and Sutherland will be separated from one another. Formerly these counties were all included in a single district.Full particulars of the different districts can be obtained from the Director, Meteorological Office, Air Ministry, Kingsway, London, W.C.2, or from theSuperintendent, Meteorological Office, 6, Drumsheugh Gardens, Edinburgh. CAIRO-KARACHI AIR MAILS THE Postmaster-General announces that the fortnightly Air Mail Servicebetween Egypt (Cairo) and Iraq (Baghdad) is to be extended to Basra. A further extension to Karachi will be made later. The following improvedfacilities will be offered forthwith :—The Air Mail from London of Thursday the 6th hist., and fortnightly thereafter, will be due to reach Baghdad late onthe afternoon of the next Thursday (7 days from London), and Basra on the Friday morning (7£ days from London). At Basra it will be due to connectwith the fast Saturday mail steamer due at Karachi on the second Thursday (14 days from London), and also with the slow service for various PersianGulf ports, leaving Basra on alternate Sundays (January 16, 30, &c). Thus, in the week of despatch, the Air Mail will offer, in comparison with trans-mission by the Desert Motor Route, or by the sea route via Bombay, a saving in time of transit of about 2 and 17 days respectively to Baghdad, about 3 and13 days respectively to Basra, approximately 7 days to Bushire and other Persian Gulf ports, and about 2 days to Karachi and North-West India(Sind, Baluchistan, North-West Frontier Province, Punjab, Kashmir). The rates of air fee payable (in addition to ordinary postage) will remain for thepresent as already indicated in the current Air Mail Leaflet (July, 1926 edition) for Iraq, West Persia and India respectively, viz. :—on letters,postcards, printed papers, &c, for Iraq, 3d. per oz., for Persia, South and West, Arabia North East, 3d. per oz. ; India, 6d. per oz.
