Normal or nasty?
Turbulence made by aircraft
Recently on the forum someone asked “what was the cause of a sudden very short lived bit of turbulence?”
Here’s the answer…this picture shows what happens to the air behind a plane…not unlike a wave behind a ship at sea. You can see that the air swirls around immediately behind the wing. If you happen to fly thru’ this you’ll feel a jolt.
And just in case you’re worried…Air Traffic Control keep aircraft apart …by miles to minimise the effect.
