Thanks to Rising Wings Aviation Channel, here is a very interesting video on airplane navigation aids (NAVAIDs) such as VOR (Very high frequency Omnidirectional radio Range), and how to use the OBS (Omni Bearing Selector) knob both on CDI (Course Deviation Indicator), and VOR; DME (Distance Measuring Equipment); VOR/DME; TACAN (Tactical Air Navigation); VOT (VOR Test facility); and VORTAC (co-located VOR & TACAN beacon):
This is what the next Airbus aircraft should be in the 40 years to come. The new Airbus concept is to match the passengers’ demand.
According to a consultation with the customers, 96% of them want more environmentally sustainable aeroplanes. The aircraft of the future will have to be fully recyclable, more sustainable ie eco-efficient, and less stressful:
Now, the leading aircraft manufacturer is using the feedback to paint its vision of sustainable aviation in 2050.
There is a need among the passengers to reduce the time spent in airports. The new Airbus concept cabin will integrate an additional door for faster boarding, and exit. This airliner of the future will reduce its noise, and carbon emmissions. It will use the latest technologies – bionic structure, blended airframe, enhanced laminar flow and noise reduction; blended U-tail, biomorphing seats able to collect the passenger’s body energy, cutting-edge relaxation systems, human body thermal recycling, dramatic panoramic view, World Wide Web access, round of golf, etc. Watch the video:
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:
Some pilots experienced very difficult conditions at Bilbao Airport a few days ago as strong crosswinds – up to 60 miles per hour – swept the runway from starboard (in French: tribord) ie from their right handside, forcing several of them to go around (in French: remettre les gaz):
