Do Electric Airplanes Reduce Emissions?

David Pflieger explains whether or not airplanes actually reduce emissions.

Electric power is the future. It is designed to overtake traditional dirty fossil fuels in a big way over the next decade or so. From the sleek electric cars of Tesla to he solar roofs that are popping up on houses all over the sunnier parts of the world, the electric industry has never been bigger. But what about airplanes?

In the modern age, flight is simply a fact of life. Everybody needs to get around somehow and if the destination is far and time is of the essence then there really are not any better alternatives. Nothing can compete with the efficiency of an airplane. It is therefore too bad that airplanes are themselves not very efficient when it comes to fuel consumption and CO2 emissions.

Despite all of the optimism coming out of the current electric industry, the truth is that jet-fueled airplanes are not going to be replaced any time soon. In order for a viable alternative to take over, the new source of energy would have to be comparable in efficiency to jet fuel. The reality is that nothing can compare to jet fuel except rocket fuel, which is even worse for the environment.

Current electric vehicles make use of lithium-ion batteries. This is what powers everything from the cars of Tesla to the electric subways that make their way through the English countryside. Lithium-ion power has seen several advances within the last few years and has proven to be a viable competitor to gasoline. Even so, it is not without its downsides.

Test Flight of A ‘Blind’ Drone

David Pflieger explains the importance of the first test drive of a “blind” drone.

Drones As We Know Them Now
Many of us are familiar with drones hovering over a football game or getting a stunning photoshoot in a national park. These drones usually require a line-of-vision range for the human operator. Others rely on ground-based radar to follow a pre-selected flight pattern. This has been the standard for drone activity since its inception. Change is in the air.

The Blind Drone
A blind drone is one that does not rely on an operator directing them. It also does not depend on ground-based radar. Instead, it uses an onboard program known as a collision-avoidance system. This allows the drone to fly independently. It can avoid obstacles and maintain its programmed route. The potential applications are significant.

Tests in Alaska and Kansas
Testing in Alaska earlier this year involved a blind drone competing with one operated by a human. The goal for each was to fly towards a vehicle and avoid hitting it. The onboard guidance system provided by Iris Automation won over the human-guided drone. This led to further testing in Kansas. In this test, the blind drone had to operate beyond the operator’s line-of-sight. The success of the test led to FAA-approved innovation to permit longer flights. Prior to this, the FAA required drones to utilize either the human controller and their field of vision, or the ground-based radar, which is expensive to install.

This Retired 747 is Testing the Engines of the Future

David Pflieger highlights the 747’s testing of a brand-new engine.

Airplanes have a limited life expectancy. They last for years, but every plane will eventually wear out and retire from active service with an airline. Some of them end up as scrap while others find their way into new roles. Rolls-Royce has acquired one of those retired planes for research purposes. They plan to use it to help test new engines that may see use on the planes of the future.

The Plane

The test plane began life as a Boeing 747, one of the most common jets among modern airlines. It flew for one of the world’s oldest and largest airlines, Qantas Airways Limited, for two decades before transitioning to its new role. It will need roughly two years and millions of dollars before it is ready to take to the skies again.

That investment of time and money will equip the plane with both a new engine and all of the special instruments that it will need to track the engine’s performance while it is still in the air. The modifications will ensure that the jet is as much a research station as an aircraft. It is certainly a large project, but it is likely to go smoothly. Rolls-Royce has plenty of experience because the company has already converted another Boeing 747 for research purposes.

The Project

Rolls-Royce plans to use their plane to test one of their latest designs, the UltraFan engine. The company hopes that the new engine will offer more fuel efficiency than modern engines, improved safety, and a higher level of general performance. The improvements will benefit both the environment and the passengers on future planes. That type of improvement may seem like a tall order, but Rolls-Royce is confident that it can get the job done. They have a large team working on the project and plenty of technical experience. The company hopes to start deploying the new engines within a decade.

The Future

It will take years of tweaking and testing to prepare the new technology for deployment. After all, jet engines are highly complicated devices and Rolls-Royce needs to be sure that they are safe before deploying them. Their newest test plane will definitely have a lot of work to do in the coming years.

The Most Commonly Connected Airports in the World

David Pflieger highlights the most commonly connected airports in the world.

While it is easier to get a direct flight than ever before, there is still a very good chance that you will have a layover the next time you fly. This is especially true if you are flying out of a relatively small city. This is done because airlines need to consolidate passengers onto one flight to a major connected airport in order to save money. These are four of the most commonly connected airports in the world.

Chicago O’Haire

O’Haire International Airport deals with more flight connections than any other airport in the world. Chicago is the perfect location for a connected airport because it is centrally located in the country. Airlines throughout the country can divert their passengers to Chicago without having to spent a lot of money on fuel. While there are dozens of airlines operating out of Chicago O’Haire, American and United handle the most flights at the busy airport.

London Heathrow

If you are flying from the United States to Europe, then there is a very good chance that you will have to catch a connecting flight at Heathrow Airport in London. In addition to being the busiest airport in the world, London Heathrow is also the closest major European airport to the United States. Passengers heading overseas make a quick pit stop in London before catching a short flight to their final destination.

Dallas-Fort Worth

It is far easier for airlines to keep costs low if they operate out of a single hub city. They can transfer all of the passengers in small cities to the hub city before dropping them off at their final destination. This operating strategy is a major reason why you are likely to experience a layover at Dallas-Fort Worth International Airport at some point during your travels. This popular airport serves as the primary hub city for American Airlines.

Hartsfield-Jackson Atlanta

Delta Air Lines uses the same hub city strategy out of Hartsfield-Jackson Airport in Atlanta. Passengers flying to or from a small city on the East Coast of the United States will get rerouted to Atlanta at the start of their trip. The Atlanta airport handled more than 107 million passengers last year, and 73 percent of them were on flights operated by Delta.
