BENEATH THE WINDSOCK

DIRECTIONAL SYSTEM OF CONTROL. A new directional system has been introduced whereby all flying in cloud or in conditions of bad visibilty shall as far as possble ,be subject to a uniform system of control. For the purpose of these regulations such conditions are deemed to exist when' the horizontal visibility is less than 1,100 yards (1,000 metres), states ‘Shell Aviation News.’ . Over the whole of the British Isles flight at altitudes. from sea level to 1,500 feet is not regulated. Immediately above 1,500 feet _ comes the layer of radiorcontrolled flights. This extends up to 3,300 feet over most of the country, but is given more depth where transport is thick. The result is that the actual directional system does not operate at all in Area 1 (Kent and part of Sussex), which is affected only by the new altitude allowed to unregulated flights above and below the controlled layer, 1,500/18,600 feet. As is seen from a course-height indicator which has been issued by the British Air Ministry, the scheme divides the available depth into four main la vers, each of 4,000 feet. These begin respectively at 8,300, 7,000, 11,000, and 15,000 feet. The pilot may choose which he will use and attain, the required altitude as quickly as possible. Each layer is divided into 12 main zones of direction and height, each comprising 30deg on the compass card and 300 feet in depth. AUCKLAND METROPOLITAN AIRPORT.
A long step toward the provision of an adequate commercial airport for Auckland was taken when the conference of metropolitan local bodies unanimously adopted the Manukau site as the most suitable (stated the New Zealand Herald ’ recently). It is less than three months since the Government’s expert committee, after canvassing all the technical aspects, left the conference to choose between reclamation schemes at Point Chevalier and on the upper arm of the Manukau Harbour, west of Otahuhu. A civilian subcommittee, assisted by experts, has since examined both propositions more closely, and were able to recommend the Manukau site and support the choice with good reasons. Much credit belongs to the mayor (Sir Ernest Davis) for the speed with which the whole project has latterly been advanced and for the firm decision now reached. The initial and admittedly incomplete estimate of the cost of immediate development of the approved site has been placed at £164,000. It is a high price, but one that should be faced in fulfilment of Auckland’s manifest destiny as New Zealand’s principal air terminal and junction for internal and overseas services. The site is recommended from the viewpoints of flying convenience and accessibility, and because it is capable of development to meet all conceivable requirements in the measurable future. As considerable time will necessarily be occupied in the actual reclaiming and preparation of the area, the more need now to press on with such essential preliminaries as the form of control
and questions of finance. These may depend to soine extent on the results of the additional surveys authorised, but, if the conference proceeds in the active spirit lately in evidence, the actual beginning of this essential metropolitan service should not be much longer delayed.
