Ik AUGUST 22ND, 1946 TviL AVIATION NEWS tions were outlined for the in-clusion of the details of radar aids on these charts.On the subject of airports and ground aids, the delegates;onsidered the use of heavier ircraft in the future, and thenecessarily larger airfields which would be required.Many of the present-day main airports would be inadequate,and it would be necessary to enlarge them and provide moreample landing facilities. Ap- proach and landing systemsshould be compulsory equip- ment at all international air-ports, and it was recommended that very high intensity runwayand approach lights should be installed for use during poorvisibility periods. Agreement was reached onseveral points concerning stan- dardization of the minimum re-quirements for airborne radio equipment, and the conferencerecommended that in order to meet the common needs of international operators it was' desirable to pool international communications. The airlines were ft/GHr LONDON AIRPORT PROGRESS : A new photograph of Heathrow showing the present state of the runway construction. Considerable progress has been made recently. FUNDAMENTALLY to make their own arrangements for the types of safety equip- "D.O.A.C. are not yet able to forecast a definite date when thempnt to be carried on board aircraft, but it was recommended J-J Constellations will he harlr on thf trnncatlantir et-nrii-fmen that Governments should be responsible for surface protectionarrangements. Disagreement with P.I.C.A.O. featured on the subject of meteorology, by preferring an alternative to theP.I.C.A.O. system of classification of the route forecasting ser- vice based on distances and routes. The alternative recom-mendation being a classification on the basis of the type of meteorological service provided. The P.I.C.A.O. system does not allow for the varying charac-teristics of flight of different aircraft over the same route, whereas the I.A.T.A. recommendation will provide for differentaircraft obtaining different met; services for identical routes in accordance with their requirements, which may vary con-siderably. This is particularly important in view of future developments in the speed of aircraft and the heights at whichthey will fly. With certain suggested modifications, the con- ference approved the newly developed international code. As announced in Flight of July 25th, the conference wasunder the chairmanship of Mr. A. C. Campbell-Orde, the assistant to the Chairman of British Overseas Airways. Constellation l b back e transatlantic service,but Trans-World Airlines have announced that their Constella- tions will be flying again on the routes on September 1st.The principal modifications have now been announced and are as follows: (1) Replacement of bulkhead electrical con-nectors by re-designed assembly, and of aluminium conductors in generator circuits by copper cables; (2) insulation of circuitbreakers to eliminate shorting, or their replacement with copper fuses; (3) additional fire extinguisher protection in the rearsection of the power plant installation; (4) installation of improved exhaust collector rings. There are also some otherchanges which involve re-design of certain items in the elec- trical and hydraulic systems. It is understood that the manufacturers will flight-test theaircraft before Constellations are permitted to go into service, and subject to these tests being satisfactorily completed, thatimproved operating and maintenance techniques for car- burettor engines will be incorporated in the operating certifi-cates of the airlines. The C.A.A. has also approved the pro- gramme agreed to by airlines and manufacturer for the pro- TALL-TAILED TUDOR : The Avro Tudor II with its new tail unit has already made public appearances. This new view shows how a similar tail has now been incorporated on the Tudor I. The remarkably clean installation of the four Rolls-Royce Merlins JJs is also apparent.
