London’s Heathrow boosts quiet electric aircraft

by David M. Sykes, Vice Chair, The Quiet Coalition

Insiders say the next big wave of disruptive innovation in commercial aircraft will be quiet, electric engines. In fact, Airbus says they can deliver by the early 2020s. And London’s Heathrow airport has added it’s own $1 million prize to accelerate the race, offering free landing charges for a year to UK’s first electric plane.

Can we get some of those quiet jets in the U.S. too, please? But hurry up, because global air traffic is expected to double in the next 15 years. So if you think it’s noisy out there now, imagine the din with twice as many flights overhead. Clearly something needs to happen quick.

In fact, electrically-powered aircraft are already here (we’ve written about this here). So the experts are serious and aircraft manufacturers, airlines, and regulatory authorities acknowledge that this really will be a major disruption. There are currently between 15 and 100 projects (depending on what you’re counting) underway worldwide on the development of commercial scale electrically-powered airplanes.

So with America’s aerospace leaders (e.g., Boeing and GE) dragging their feet on this, it looks like we’re handing Airbus and others a big win.

Perhaps some of America’s biggest airports should look closely at Heathrow and think about getting into this prize game too. Something needs to be done to wake up America’s air transportation industry that BOTH noise and fuel efficiency matter to their customers and their neighbors. If they don’t change soon foreign suppliers like Airbus will walk away with the business.

The EU wants quiet, fuel-efficient airplanes sooner

Some encouraging news this week from the BBC on the EU’s effort to develop quiet, fuel-efficient aircraft engines. Here’s how the BBC summarizes the situation:

Modern jets aren’t nearly as noisy as their predecessors from a couple of decades ago, but they still make quite a racket on landing or takeoff. If your house is close to the airport that’s bad news. Electric motors are a lot quieter, so they could allow more night flights, especially in airports close to city centres. And of course, there’s the question of emissions. Electrified aircraft, like hybrid cars, should be cleaner than conventional models.

If you live near an airport or beneath a glide path, you’re certainly wondering how soon “quiet” aircraft might appear, right? Well, according to the BBC, so do Airbus and it’s partner Siemens, as the BBC writes that “[t]he firms want to fly a demonstrator version of the plane by 2020, with a commercial application by 2025.”

If that’s not soon enough for you then get in touch with your Congressional representative and tell him/her that you want them to support the work of the Congressional Quiet Skies Caucus and the National Quiet Skies Coalition.

Tired of jets flying over your neighborhood? Here’s what FAA is (not) doing to help you

By David Sykes, Vice Chair, The Quiet Coalition

You may already know about the movement in Congress to address the problem of aircraft noise. A specific congressional caucus, The Congressional Quiet Skies Caucus, was formed to encourage the Federal Aviation Administration (FAA) to address the problem of aircraft noise around airports, specifically the problems caused by FAA’s “NextGen” program. “NextGen” is a bungled FAA program that has made the noise problem much worse for many communities across the USA–35 communities are already aligned with The Congressional Quiet Skies Caucus.

The noise problem applies to all airports, not just big-city transportation hubs. A recent Sun Sentinel article about NextGen problems in Ft. Lauderdale, Florida is a good piece to read about NextGen because it spells out what the FAA is—and isn’t—doing to “help” affected communities. Bottom line: If you squawk loud enough and long enough, they may agree to replace your windows and doors with “sound-insulating” ones—but how much money you might get depends on the assessed value of your house. But replacing doors and windows doesn’t stop the earth-shaking vibration from big jets, and it certainly doesn’t stop the noise outdoors in your backyard. As long as the FAA and its parent, the Department of Transportation, perpetuate the decades-old myth that noise is “merely annoyance” (i.e., has no appreciable effects on you other than to make you irritable), all you can do it take their money and suffer quietly. Only by changing the discourse and carefully spelling out that noise is a public health hazard will communities have the chance to turn this situation around.

The Quiet Coalition Chair, Daniel Fink, MD, asked me to add this note:

“Rest assured that if you are bothered by aircraft noise, you are not alone! ‘Noise as a Public Health Problem’ was the theme of the 12th Congress of the International Commission on the Biological Effects of Noise (ICBEN) which recently took place in Zurich. I presented two papers there and am now preparing a summary of what I learned. The European Union is well-aware of the adverse health effects of transportation noise (aircraft, rail, and road traffic noise) and is taking steps to minimize its effects. I also presented a paper on the adverse health effects of transportation noise at the Institute for Noise Control Engineering meeting on June 12 in Grand Rapids, Michigan.”

There’s another very hopeful perspective on this problem, although admittedly down the road a few years: the development of quiet (electric) aircraft. Lithium-ion battery-powered airplanes and helicopters have already been developed and flown in Germany and in the U.S. So take heart, quiet electric aircraft could very well be flying by 2027, the 100th anniversary of Charles Lindbergh’s historic transatlantic flight.
