NASA Langley Research Center in Hampton, Virginia – New energy-efficient airplanes could be designed. Researchers work on designs for viable commercial aircraft which could leave a low to zero carbon footprint.

In order to save jet fuel, they look at new concepts, processes, and designs that could be lighter. They try to reduce drag, and they try to increase the propulsive efficiency. For this purpose, they try to get rid of metallic airframes, and parts as often as possible.

For instance NASA has a newer composite 10 percent lighter than carbon fiber composite. This advanced material is called « Pultruded rod stitched efficient unitized structure » or PRSEUS.

The new sleeker designs look like large wings without any traditional tube-shaped fuselage in the central part since it is blended with the wings. These futuristic designs are more fuel efficient as the more lift the plane has, the less it consumes fuel.

The researchers also look at new energy sources as it is showed in this video, and in the end there is further information about the NextGen project which could save fuel too, thanks to this new form of air traffic management:


Airlines extra fees in 2010: $22 billion!

According to a Wall Street Journal report, the American carriers have made a lot of money thanks to add-fees – $22 billion in 2010.

For instance, Matt McCall, the president of Penn Financial Group reports in the following video that he had to « pay 50 dollars for 4 inches » exceeding the standard luggage size the night before.

Most people pay such add-fees as they do not want to change bags in the very last minutes. It depends on the airlines – as in the video – but the fee for overweight carry-on bags can be twice as expensive. Some passengers are willing to pay add-on fees if needed.

However some other passengers may not have time to perform the luggage change required, and they pay add-on fees just before departure. So they pay, and the airlines rake the add-on fees revenue which is to increase even further:

Discrimination in the skies? UK’s Air Passenger Duty explained

Every passenger departing the UK has to pay a fee. It varies depending where you are flying to, and where you are sitting on the plane. APD – Air Passenger Duty – is divided into four categories or bands based on the distance between London, and the final destination. Watch the video about this « banding system » hereafter:
