These two #A350 “fellos” performed the 1st transatlantic flight as paired aircraft from Toulouse to Montreal airport! What’s #fellofly? A follower retrieves wake energy lost by a leader, reducing engine thrust & fuel consumption of over 5% per trip.
Seems like a huge number as savings go. Billion dollar PIP's usually aspire such numbers. This seems like simple change in processes to achieve 5% improvement.
If this really pans out I would guess that we will have lanes in the sky to make sure that everybody benefits from this reduction in costs and emissions...
