航空交通における空域問題

航空地理学研究の一課題として

抄録

The purpose of this thesis is to describe an introduction on the study of Aeronautic Geography. To begin with, basic problems must be considered in the study of air transport. We should particularly try to consider airspace as the most important problem in various aeronauticgeographical ones of air transport.
At first, it is taken up that the study of meteorological airspace is the most basic problem. Because the problem is directly concerned with the safe take-off, flight and landing of aeroplane.
Next, we have the international problems of territorial air and Flight Information Region (FIR). The former is a political and difficult problem in the international diplomatic relations. The latter is a social and co-operative problem in the international air transport.
And, we could not get the same significance and character in airway area as other transport routes. It has been said that the first factor of the three air transport elements is aircraft and the rest of them are airway and airport. We have a colored airway with N. D. B. and a victor airway with V. O. R.. In general civil aviation, we should take up both international airway and domestic one.
At last, we pick up three problems in the airspace of airport. First of them is the problem of meteorological area as a basic one of airport. Second is the problem of the control zone for Air Traffic Control (ATC) as a functional one of airport. The last is the problem of the positive control area as a special one of airport. We should particularly investigate the importance on ATC in airport.
In this way, through an aeronautic-geographical consideration on air transport, we could not keenly help feeling that Aeronautic Geography will meet further important problems in the future.
