International flight and flying-over are increased. Domestic flight is dependent on the case of GDP.

Even if GDP is estimated low, the number of aircrafts will exceed the limit of air traffic control capacity around 2025.

The demand may go up rather than this forecast by further promotion of inbound tourism and the growth of LCC.

Demand forecast of air traffic in Japan

* Basic case of GDP is set up based on the economic growth rate which is a target of the Japanese future strategy.

(economic growth rate is set up to 1.7% from 2010 to 2017 and 2.0% from 2017 to 2032)

* In upper case, economic growth rate is set up 1% higher than basic case.

•In lower case, economic growth rate is set up 1% lower than basic case.

•The number of IFR flights is that to add military, non-scheduled and cargo flights to those above.

Expectation of Air Traffic Flow Control

・On the Ground due to flow control : 270 traffics

・Average of delays : 25 min or over

⇒flight cancellation will occur

2025年頃の制御想定

・On the Ground due to flow control : 60 traffics

・Average of delay : 8 min

In 2025, airspace capacity in the current airspace configuration becomes

the limit.

We order to respond to an increase in the future traffic demand, conventional and different, to

expand the ATC capacity by the airspace divided by altitude.

・By difference of cruising, climbing, and descending, we raise the treatment capacity of aircraft.

・In the high altitude airspace of low workload, the handling number of aircraft makes to increase.

✓Handling ability of Air Traffic Control was raised by reducing number of aircraft per 1 sector by

subdivision of a sector conventionally.

✓However, enforcement of subdivision beyond this will increase the time and effort of taking over

between sectors. Moreover, the airspace that detour for bad weather or turn order of an aircraft

becomes less insufficient, and throughput declines conversely.
