Preview new version of Explane site

Dear followers and users of the Explane app. We have made available a preview of the new open access website with all data that is gathered by you using the app. Please visite https://reports.explane.org/preview.html.

We would appreciate it very much if you provide us with feedback. Is the new site easy to use, do you understand all the presented data, do you need more explanation about what you see? Please mail us at [email protected].

You can visit the current site at https://reports.explane.org to see the changes.

Explane data now publicly available

A few moments ago we have put our new website live that gives you open access to all measurements made with this app.

Please visite https://reports.explane.org and play with the data. Let us know what you think about it, what has to be made better and what information you like or dislike.

Please mail us your feedback via [email protected] or via our form at https://cms.explane.org/feedback.

We need your feedback to improve our site from this first version to the next version! We appreciate that you made over 12.000 measurements in the first phase of this civic science project.

Soon available: web site to explore Explane data

We are nearing the completion of the first version of the web site which will enable you to explore all the data that is gathered with the Explane-app.

The site will allow you to browse all the data, visualize it and choose that information that is interesting to you.

You will be able to choose your own region, to see which airplanes produced the most noise and how many measurements were made in your city.

Currently we are testing the site. Once finished we will publish the site address here and on social media. Please have patience for another week and you will get rewarded!

Tips & tricks: keep your phone out of the wind

In our database you filled with aviation noise measurements we see sometimes strange curves. We suspect that these are caused by users who try to measure the aviation noise while standing in the wind.

‘Regular’ measurements show a relatively slow upcoming and dying noise profile. But some of the measurements show more than one top and bottom. We will flag these measurements to distinguish them from the regular registrations.

We will keep these ‘odd’ measurements in our database, to give scientists the chance to analyze them, but we will not show them in our regular overview on the upcoming website. Read more >

First preliminary result from Explane app

The thousands of aviation noise measurements from users of the Explane app have led to a first preliminary result. This could lead to broader noise corridors and thus even more impacted homes.

Measurements show that planes make (much) more noise when they fly over a densely populated area with lots of ‘hard’ materials like bricks and asphalt. The same planes show a lower noise level in an area with ‘softer’ materials like fields, trees and sand grounds.

Airport calculations of noise nuisance do not account for these differences in environments.

If this first result is proved after further research, airplanes cause much more noise pollution in urbanized areas, causing much more nuisance than what was calculated until now by aviation sources. Read more >

Aviation CO2 emissions: the real story

More than once we read stories from the aviation industry that their CO2 emissions do not exceed 2% of a country’s total. We did not trust these fairy tales and decided to do some calculations on the Dutch emissions. Spoiler alert: aviation is not telling the truth.

Following the most recent numbers the Dutch Bureau for Statistics CBS announced in Holland 3.75 billion kilograms of kerosene was sold in 2016.

Burning 1 kg kerosene gives 3.14 kg of CO2, resulting from the chemical formula to transform one CH2-group (fuel) with atomic weight 14 to a CO2-molecule with atomic weight 44 (44 devided by 14 equals 3.14). Read more >

Dutch government secretly spends 744 mln on French-Dutch airliner

This week the Dutch government spent nearly 800 mln community money to gain a 14% interest in airliner Air France-KLM. Stock prices tumbled over 10% following the announcement of the purchase. French government is furious.

The Dutch bought the shares secretly, without sharing its intentions with other shareholders and the French government. As a result, the French are likely to block another term for KLM-CEO Pieter Elbers.

A week ago Elbers mobilized 25.000 KLM-employees to plead for another four years of his presidency of the company. This convinced AFKL-CEO Ben Smith to promise Elbers a new term. Read more >

Archaeological sites Peru threatened by airport construction

The construction of a brand new airport near the world famous city of Machu Picchu in Peru destroys archaeological sites that are yet unexplored.

The airport aims to ease access of tourists to the former Inca capitol. Archaeologists, anthropologists and historians claim it will destroy cultural riches visitors come to see.

Nearly 200 Peruvian and international experts have signed a protest to the national government asking to suspend construction and consider relocation of the project.

The current location of the project overlooks Peru’s Sacred Valley, one of the first areas conquered by the Incas in the 1300s. Incan agricultural terraces still cover the mountainsides around this spot. Read more >

New Twitter-account for Explane

We just opened a new Twitter-account for the Explane-app. Via this account we’ll inform you about the newest developments in our work.

The first tweet mentions the 4.000 registrations that have already been made since we launched the app.

Also we mention the hard work that is going on to produce an interactive web site to present reports. The registrations will be accessible for anyone with an interest in the problem op aviation noise and its nuisance.

No outcome for consultation Schiphol Airport

After years of consultation between residents, the aviation industry and politicians, earlier today became clear that there will be no outcome of this process. Parties could not reach an agreement about the future of the airport.

In December last year the consultation seemed to head up to an extra 25,000 flights for Schiphol until 2023. At the beginning of this year the president of the residents was taken out of the talks because of this threatening outcome.

Since the forced change of the spokesman residents forced a zero growth in the negotiations. Mayors and politicians of neighbouring cities and the Environmental Federation (Milieufederatie) backed citizens in that pursuit . Read more >
