More on airspace redesign

In the previous installment we addressed the implementation of the redesign of the airspace of Mexico City, and the implications in terms of safety and noise pollution, in this sense I commented that according to experts in data management related to means of transport, the Noise pollution, as a result of the new air routes, will impact a 65 percent larger area of ​​the metropolitan area of ​​the Valley of Mexico, which translates into 1,206,048 additional people will be affected by this new aerial approach, only considering that currently the AICM It is operating at 50 percent of its capacity and still ruling out the entry into operations of what will be Felipe Angeles International Airport.

The way to measure noise is through decibels. In this sense, the new routes that began to fly in Mexico City since March 25 at an altitude of less than 900 meters generate a noise level that ranges from 65 to 85 dB depending on the type of plane; for reference a vacuum cleaner emits noise at 70 dB. In Mexico there are no standards that regulate noise pollution from airport operations. The only one available is actually to certify the noise produced by aircraft at a distance of no more than two thousand meters from the airport.

On the other hand, other countries have regulations that refer to an exhaustive, permanent and consistent measurement of the noise caused throughout the day and night by air traffic, which among other things is used for the imposition of fines and compensation for damages to the affected. According to noise and noise pollution experts like Dr. Jimena de Gortari, It is considered that the noise caused by airplanes is not only due to their engines but also to the friction of their fuselage against the wind and to the use that aircraft make of mechanical means (ailerons and spoilers) to turn and reduce their speed during the flight. descent, which magnifies the noise generated by the aircraft, which has become very evident in the southern area of ​​Mexico City where, to top it off, the passage of airplanes has forced a reduction in the height of the helicopter flight, which further aggravates the noise problem.

It will be this Friday when the General Directorate of Railway Development, of Manuel Gmez Parra, receive offers from companies interested in building the new Vasco de Quiroga station of the Mexico-Toluca Train that was added to the original plan. According to the clarification board on the list are Caabsa, of Lewis Y Mauricio Amodio; La Peninsular, from Carlos Hank Rhon; Aim of Santiago Villanueva and Constructora de Proyectos Viales, a subsidiary of OHL. Remember that until a few months ago there were only two stations: Santa F and Observatorio, the latter connecting with the CETRAM project and the extension of line 12.
