Fly like a bird to save fuel

Birds fly in a V to help conserve their energy during migrations. With the exception of the individual leading the group, each bird trailing behind the other benefits from a reduction in wind resistance.

In principle, the idea of flying aircraft in formation is the same as for migrating birds. While in formation, birds experience lower drag and therefore can fly further. Aircrafts can take advantage of the same principles to reduce their drag.

In fact, arranging aircrafts in a three plane inverted-V formation could save 12% of fuel compared to what it would burn if each aircraft flew alone.

To put things in perspective a plane like a Boeing 747 uses approximately 4 litres of fuel every second. Over the course of a 10-hour flight, it can burn up to 150,000 litres.

A 12% reduction would save thousands of litres of fuels, not to mention the related greenhouse gas emissions. Read more here.
