Airbus A380: ten years in the air. One sudden fact from the Nature

The most pronounced lunar gravitation effect on the Earth consists in presence of tidal floods. But one may note that it has also a modest effect in daily airflights. The effect is meaningful for heavy airjets like Airbus A380 or An-225 Mriya. Assuming the full takeoff weight of A380 to be 560 tons the lunar gravitation force makes the airplane lighter for 18.58 N or almost 2 kg. In another words one handcase becomes free of charge if the Moon passes its way above the flying A380.
