So, we need to restrict you peasants from taking fossil fueled flights. Not the Elites, of course
Climate change will ‘lead to noisier take offs’
Scientists have discovered that warmer air from climate change will create more noise pollution from departing airplanes around European airports.
Researcher’s from the University of Reading have been studying how rising air temperatures change the way aircrafts take off.
On average, departing aircraft climb angles will decrease by 1-3%, but individual hot days could reduce climb angles by up to 7.5%.
Dr Jonny Williams, lead author at the University of Reading, said: “Over the next three decades, thousands of extra people in London could be blighted by noise pollution caused by climate change.”
So, this is all about climb angles. Commercial jets typically take off at 5-15 degrees of pitch, and rarely exceed 20 degrees when they are higher up. So, what, the angles will be 5.89-14.79 degrees? It’s like saying people can really notice the difference between 70F and 71.7F. Planes will still take off the same, typically you see about 10 degree for a typical airport. High altitude airports tend to have lower up angles.
They focused on the 50-decibel level, which marks a boundary where aircraft noise becomes more noticeable to residents.
The team studied how climb angles of the Airbus A320 commonly used for short European flights affect this threshold as the climate changes.
In central London, around 60,000 people currently live within the 50dB noise footprint of a typical A320 aircraft.
Changes in climate and population density could mean around 2,500 additional people are brought into this boundary.
Whoop de do. Except the takeoff angle won’t really change. Heathrow is supposedly limited to 5 degrees, which is weird, because they try to limit noise, hence their approach angle for some bigger jets is 3.2 instead of the typical 3.0, a slightly higher angle to reduce noise time. Not quite a slam dunk.
Dr Williams explained that the problem gets worse with different types of sound. Low frequency noise which travels further will “increase the most” whilst deeper sounds “annoy human ears and can cause stress and sleep problems”.
“Without action on greenhouse gas emissions, rising temperatures will make managing the problem of airport noise more difficult, even as engine technology advances,” he said.
Maybe do not live near an airport? Remember, these same people have no problem forcing people out in the countryside to deal with the noise and constant blocking of sun as blades revolve.
Let’s start with the action by banning politicians and climate cult scientists from taking fossil fueled flights.
