New flight routes at Haneda Airport Passenger planes fly for the first time over central Tokyo

New flight route at Haneda Airport Passenger plane first flight over central Tokyo April 20 20:24

In order to increase international flights at Haneda Airport, a new flight route began operation, and at 3:00 pm on March 3, passenger aircraft flew for the first time over central Tokyo, such as Shinjuku and Shibuya.

At Haneda Airport, a new flight route that passes over the city center will increase international slots by approximately 1.7 times, thereby increasing the number of flights per day by 50.

Passing over the city center from 3:00 pm to 7:00 pm when the south wind blows, the assumed altitudes are 900 m or more in Shinjuku, 750 m or more in Shibuya, 450 m or more in Shinagawa, etc. You.

On the 3rd, conditions began in the southern wind for the first time since the operation started last month, and passenger aircraft flew over central Tokyo such as Shinjuku and Shibuya just after 3:00 pm.

Then, before 6:00 pm, passenger planes passed over the city center one after another, and according to the Ministry of Land, Infrastructure, Transport and Tourism, there was no trouble on the 3rd flight.

Concerns over the new route, such as the noise of passenger aircraft and falling parts from the aircraft, have caused opposition groups to request that the route be withdrawn.

What is the new route

Until now, airplanes that land at Haneda have basically been operated in a way that minimizes the impact on the city center, such as entering from the Tokyo Bay side and taking off aircraft rising toward the sea.

However, this method did not significantly increase the number of departures and arrivals.

At the runway at Haneda Airport, the landing and takeoff routes intersected, and time was lost to avoid approaching.

However, by landing from above the city center, the same runway can be used for takeoff and landing, and the number of departures and landings can be increased.

There are two main routes that have been newly established, but the routes that pass over the city center are used by arrival aircraft when the south wind blows.

The expected altitude of passenger aircraft is about 900 meters in Shinjuku, about 750 meters in Shibuya, and about 450 meters in Shinagawa.

Operating hours are between 3:00 pm and 7:00 pm, when international arrivals and departures are concentrated, and it is about three hours excluding traffic control.

Noise and falling objects

According to the Ministry of Land, Infrastructure, Transport and Tourism, the noise measurements of flight confirmations conducted by passenger aircraft conducted by February were the largest, with 78 dB in Shinjuku, 79 dB in Shibuya, and 81 dB around Oimachi Station. It was measured.

This is equivalent to the noise of the vacuum cleaner, the side of the main road where cars come and go, and the noisy street, so the Ministry of Land, Infrastructure, Transport and Tourism said that it was `` generally as expected '' and continued to take necessary measures It is to proceed.

Another thing to worry about is falling objects from aircraft.

Three years ago, a panel weighing about 3 kilograms fell twice from an ANA departure from Narita Airport, and a panel weighing about 4 kilograms from a Dutch aircraft taking off from Kansai Airport was located in the center of Osaka City. And collided with a moving passenger car.

According to the Ministry of Land, Infrastructure, Transport and Tourism, a total of 489 cases have been confirmed in the post-flight inspection that parts have been removed from aircraft in the year 2018.

Of these, there were eight cases of items weighing more than 1 kg.

Many of the fallen objects are likely to have fallen to the sea where there are no people, but in the vicinity of Narita Airport, springs that have fallen or clumps of ice that have come off from the aircraft have caused damage such as breakage of agricultural houses and roof tiles. 23 cases have been confirmed in the 10 years until 2018.

Under these circumstances, foreign airlines have not had to report falling objects so far. We asked them to report missing parts.

In addition to requesting airlines to take measures to prevent falling objects, the government has been strengthening unannounced inspections of the aircraft, and will be punishable by airlines if there is a violation.

According to the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, we will work to reduce noise and falling objects to the extent possible to dispel residents' anxiety.
