bered 40, 41, and 42, while the Tellier-Hispano boat is numbered47. A three-engined Caudron, piloted by Poiret, also arrives, and is moored to a buoy. This machine is similar, in ageneral way, to the large cabin machine shown at the.Paris Aero Show. It is, however, of smaller dimensions and hasno enclosed cabin. The engines—three Le Rhones—are mounted as were the Salmsons in the Show machine, i.e.,one in the nose of the fuselage and two on the wings, all driving tractor airscrews. This arrangement, for a given total enginepower, would appear to possess certain advantages over the twin-engined machine with its engines on the wings. Forinstance, suppose the total horse-power is 600 h.p., with each engine placed 6 ft. out from the fuselage. In the twin-enginemachine, if one engine stops, not only is the power reduced by half, but there is a turning moment of : Thrust of 300 h.p.by 6 ft., which has to be counteracted by the rudder. In the three-engined machine, if the fuselage engine stops thereis a loss of only a third of the power and no turning moment. If one wing engine stops the resulting turning moment is only :Thrust of 400 h.p. by 3 ft. If the thrust h.p. is 4 lbs., the yawing moment on the twin-engined machine is 4 X 300 x 6= 7,200 lbs. ft. On the three-engined machine, however, the moment is only 4 x 400 X 3 = 4,800 lbs. ft. Whether,therefore, one looks at it from the percentage loss of power or from the yawing moment point of view, the three-enginedarrangement would seem to score over the twin-engine- on-the-wing system. This Caudron has two rectangular section floats, placedone under each wing engine, and although the floats are not very long, the machine does not get its tail down when restingon the sea. There is a small cylindrical tail float of copper, but this does not appear to be really required, nor does itseem to be of sufficient volume to support the tail unless assisted by the main floats. As Nieuports have only Lecointe here, there is now no pilotfor the small machine, and one therefore doubts if this will take part in tomorrow's speed race. In the Spad hangarthe mechanics are busy changing the wings, taking off the planes used in the altitude flights and substituting racingMnngs. These, as on the Bournemouth machine, are charac- terised by a top plane which is of considerably smaller spanthan that of the bottom plane. It should be added that in the Spad machines ailerons are fitted to the bottom planeonly, and the lateral control is, therefore, probably only little affected by the fitting of a smaller top plane. Just before 11 another machine hove in sight, whichappeared to be very fast. This proved to be one of the old type Hispano-Spads piloted by Ensign Tece, who did a sortof half-roll-half-loop-half-Immehnan-turn before alighting. His landing afterwards was far from perfect, and the machineseemed utterly helpless once it was on the sea, chasing its tail like a frisky pup (not Sopwith). It was ultimately towedin by a boat and hoisted on to the North Quay, where it was found to have sprung a very bad leak in its starboard float. It is hoped that the Savoia racer may arrive in time for APRIL 39, 1920 this race, andTits appearance is naturally awaited with^thegreatest interest as it is said to have attained over Lake Maggiore a speed of 300 kilom. (about 180 miles) per hour.If this prove true the machine is one of more than ordinary-;/ merit for a seaplane of the flying-boat type. Later. News has just come through that Lecointe and Coli on theTellier-Nieuport, Sunbeam engine, arrived at Ajaccio, Corsica, at 8.48, and at Bizerta at 2,48. A Savoia has just arrived, which proves to be piloted byJanello, of Bournemouth fame, who has come over by air, accompanied by his mechanic. He informs me that he hatestravelling by train and has made the trip in the most natural way—by air. The racer is expected to arrive by road tonightor tomorrow morning. The machine in which he came over is one of the standard Savoias, type S 13. Sunday, April 25.The only happenings of importance today were the speed trials of de Romanet on the Spad and Janello on the Savoia.The Spad's time over the 80j kilom. course to Cannes and Scale cf Miles The course for the speed tests Mentone was 22 mins. 52^ sees., equal to a speed of just over131 m.p.h., while the Savoia flying-boat took 23 mins. 46f sees.; Janello losing a little time at the start and appear-ing to go wide at the turns. Monday, April 26. A message has come through that Lecointe has made thestage from Bizerta to Tunis and Susa, but on coming down at Bizerta on his return smashed his propeller. He has sentfor a new one and is held up meanwhile. Three naval flying- boats which set out to fly to Bizerta yesterday reachedAjaccio safely, but on restarting ran into fog. Two re- turned to Ajaccio, and the other put into San Antioso, Sar-dinia. - . . ., Aerial Lighthouse at St. Inglevert THE Air Ministry has issued the following Notice toAirmen (No. 41) :— " An aerial lighthouse has been installed at the aerodromeat St. Ingtevert (approximately E. by N. 7 miles from Cape Grisnez), and will be in operation every evening from sunsetto two hours after sunset. Its characteristic signal is the letter ' A ' of the Morse code, every eight seconds, thus :—Light half second, eclipse half second, light three seconds, eclipse four seconds." , . „...,. ...... _. . _• .. Lille Aerial Lighthouse <:~••-'"'*• ; " THE Air Ministry has issued the following Notice to Airmen (No. 42) amending Notice No. 24, of March 9 :— "The aerial lighthouse at Lille aerodrome, in position 'Lat. 500 37' N. Long. 130 6' E. of Greenwich, has been allotted a new signal. This lighthouse will, in future, signal the letter ' B ' of the Morse code (i.e., dash, three dots), once every ten seconds, and will be in operation every evening for a period of two hours, commencing at sunset." Lyons Aerodrome THE Air Ministry has issued the following Notice to Airmen (No. 43) :—• " Three wind sleeves have been installed at Lyons (Bron)aerodrome, to assist -pilots landing by day. Two of these ' sleeves ' are red, and are situated on the western side ofthe landing-ground ; the third is white, and is on the east of the ground. " When there is no wind, machines should land and takeoff from south to north. " Bron aerodrome is in a position Lat. 450 44* N. Long.4° 53* E. of Greenwich." Summer Time in Holland - THE Air Ministry has issued the following Notice to Airmen (No. 44) :— " Summer time was introduced in Holland on April 5 and will remain in force until September 27." Examination for Aviation Ground Engineers •..',•..--. THE Air Ministry announces :— " Arrangements have been made to hold examinationsfor candidates desiring to become certified ground engineers (aircraft or engines), under Section 4 of the Air NavigationDirections, 1919, at the following centres during May and June :—- London May 12, May 26 Manchester .. May 20 June 9, June 23 Leeds .. .. June 15Bristol .. .. May 18 Newcastle .. June 16 Birmingham .. May 19 Glasgow .. .. June 17 "A candidate may apply to be examined as a groundengineer 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, partlyoral 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 secure applicationforms from the Secretary, Air Ministry, London, W.C. 2, and should submit their completed forms of applicationaccompanied by a fee of 5s. at least seven days prior to the date on which examination is desired. Candidates shouldalso state at which of the above places they wish to be exam- ined." 470
