What is redundancy in aircraft design

Airbus presents "Smarter Skies" visions for 2050

BERLIN - Airbus has presented visions for air traffic in 2050 under the motto "Smarter Skies" that go beyond aircraft design. In order to be able to sustainably cope with the expected growth in air traffic, the manufacturer outlined five concepts that could be implemented in all phases of flight operations in order to reduce redundancies inherent in the system (waste of time and fuel, lowering of CO2 emissions).

These are in detail:

Aircraft take-off with external starting aids that are powered using renewable energies. With steeper climbs, the noise emissions at the airports could be minimized and efficient cruising altitudes could be reached more quickly.

"Intelligent" aircraft would be able to organize themselves and choose the most efficient and environmentally friendly flight routes ("free flight"). In doing so, they would make optimal use of the prevailing weather and atmospheric conditions.

On routes that are frequently flown, the planes could fly like birds in formations when cruising. The lower air resistance and energy consumption bring efficiency improvements.

Airplanes that can approach airports in gliding flight generate fewer emissions and less aircraft noise when descending, since neither engine thrust nor air brakes are necessary.

When landing, the aircraft engines could be switched off earlier and the runways could be left more quickly. This would reduce emissions on the ground. The landing position of an aircraft could be technically calculated so precisely in advance that an autonomous tow vehicle powered by renewable energies is available so that the aircraft can clear the runways more quickly.

The use of sustainable biofuels and other alternative energy sources (e.g. electricity, hydrogen and solar energy) will be necessary to secure the supply and to further reduce the environmental impact of air traffic in the long term, according to Airbus.
