^^—• FEBRUARY 24, 1921 - .r: NOTICE TO AIRMEN France—Aerodromes and Seaplane Stations, Etc. 1. NOTICES to Airmen Nos. 98 and m of 1920, are amplified and amended as follows :— 2. Aerodromes and Seaplane Stations. • *'. (i) VILLACOUBLAY.—(a) The construction of a concrete platform in the N.E. position of the aerodrome is to be com- menced very shortly. Pilots should therefore avoid this danger area, the boundaries of which will be marked as clearly as possible by strips of canvas and red and white flags. (b) Villacoublay is a private civil aerodrome owned by the Soc. An. des Aeroplanes Morane-Saulnier, and is situated 2 kms. West of Villacoublay village and 6 kms. E.S.E. of Versailles, Latitude 480 46' N., Longitude 2° 12' E. (ii) BORDEAUX (TEYNAC). (Latitude 440 50' N., Longi- tude 0° 42' W. Markings : The centre of the landing zone on this aerodrome is marked with a white circle of 50 metres diameter, situated 400 metres, 1980 (approx. S.S.W.) from the W/T mast. (iii) MONTPEIXIER. (Latitude 430 32' N., Longitude 3° 53' E.) As a result of recent floods the civil emergency landing ground at Montpellier has become unfit for use by aircraft, and should therefore no longer be used. (Note. Para. 1 of Notice to Airmen No. 111, of October 22, 1920, is amended accordingly.) (iv) BAYONNE. Civil seaplane station. Position: Lati- tude 430 31' N., Longitude i° 30' W. Situated 3 kms. north of Bayonne. Accommodation : There are two hangars^-and one slipway available. 3. GENERAL.—When any work is in progress at a French State civil aerodrome, which renders part of such aerodrome unfit for use by aircraft, the boundaries of the dangerous zone will be marked by means of red and white strips laid flat on the ground and by red and white flags. 4. AUTHORITY.—For para. 2 (i), sub-section (a), French Notice to Airmen No. 22, of January 14, 1921. For re- mainder (excepting para. 2 (i), sub-section (b))—" Bulletin de la Navigation Aerienne," No. 10, January, 1921. (No, 18 of 1921). NOTICE TO GROUND ENGINEERS • Interplane and Centre-Section Struts : Rotting in Lower Sockets 1. IN several instances recently it has been noted that the lower ends of wooden interplane and centre-section struts have rotted in the sockets, due to prolonged exposure of the aircraft to the weather under winter flying conditions. 2. The attention of Ground Engineers is therefore directed to the necessity of a careful examination of this portion of all such struts. 3. The tendency of the strut end to rot can be materially reduced by providing some arrangement to prevent water from entering the socket, thus obviating constant contact between moisture and the end grain of the strut. (No. 18 of 1921.) Top Overhaul of Engines After Storage All engines that have been in storage or unused in machines for more than three months since previous running, as recorded in the log-book, should be subjected to top overhaul before being passed by the Ground Engineer for flight. The internal condition of the engine should be carefully examined for signs of corrosion, particular attention being paid to cylinder bores and all ball and roller bearings. In addition to the usual precautions taken after top overhaul to ensure that all parts of the engine, including ignition and carburation systems, function correctly, special attention should be given to the flushing of all oilways— flushing, cleansing, adjustment, refilling, etc., of lubricators, filters, etc. (No. 19 of .1921.)

Navy and Army Canteen Board Goes ; Service In- stitutes Take Charge AN Army Council instruction states that the Navy, Army, and Air Force Institutes will replace the Navy and Army Canteen Board, and will for the future be responsible for the conduct of all naval, military, and Air Force institutes in the United Kingdom and in garrisons overseas, and of canteens in His Majesty's ships. With a view to fostering close and friendly relations between the Army and the new organisation, it has been decided that the existing Command Canteen Committee, under the name of Command Institutes Committees, will continue, and that, in addition, an Army Institutes Comxnitttee will be established, consisting "*of 129 officers nominated by the Army Council and of one officer and one other rank from each command in the United King- dom, representing their respective Command Institutes Com- mittees. At the same time it is announced that the N. A. and A. F. Institutes have decided to sell their surplus properties, and have instructed Messrs. Knight, Frank, and Rutley to offer the same by auction. The sale will include the provision depot in Regency Street, Westminster, which was for some time in the occupation of the Australian Expeditionary Force. This property has an important building area of about 21,000 ft, with lifts to each floor. The warehouses in Queen Street, Dover, and in High Street and Nelson Street, Aldershot, will also be sold at the same time. Paris-Geneva Air Line M. BUISSON, director of the Vie Airienne, is at the head of a company which has acquired the air transport enter- prise founded last July by the two air pilots, Minier and Durafour, for operating the Geneva-Paris and Geneva- Lyons air line. It is proposed to restart a regular service this year. -• >• D 2
