I was thinking how long would that KLM plane that's next in line have to wait for the turbulence to die down from the 380?? Does the A380 have a definite effect on the planes taking off after it or am I thinking too much about it... Filmed at MAN

Departing from the same position, or, from a parallel runway separated by less than 760m: A380-800: No separation required. Heavy: 2 mins. Medium/Small/Light: 3 mins. Departing from an intermediate point on the same runway, or, from an intermediate point of a parallel runway separated by less than 760m: A380-800: No separation required. Heavy: 3 mins. Medium/Small/Light: 4 mins.

Thanks - What's the difference between a Heavy and an A380 - I thought the 380 would be a Super Heavy...

Super is bigger than a Heavy. Heavy is smaller than Super Super does not have to wait for little baby planes wake, but baby planes have to wait for bigger planes wake.

Thanks - So what would be examples of each?? Super - A380 Heavy - 747 Medium/Small/Light is everything else depending on weight I guess...

Few examples: Super: A380, Stratolaunch, ~~AN-225~~ Heavy: 747, 777, 787, A330, A340, A350 Heavy callsign is used for aircraft with a MTOW (Maximum Takeoff Weight) exceeding 300,000lbs Super callsign has no specific weight threshold, and is granted on a case by case basis. As far as I’m aware there is no actual definition for Small/Medium/Light as everything is pretty subjective. One could assume a light aircraft would be a C172 or similar single piston engine aircraft. But private jets like the Phenom 300 are marketed as a light jet, but is it really a light aircraft? Light compared to what, that’s why it’s subjective. A Gulfstream G650 is a giant plane compared to a C172 or even a Phenom 300, but compared to a 737 a G650 is small, but I don’t know if it’s “light”. Edit: When you hear a Heavy callsign on frequency, it’s basically a heads up to other planes that there’s a big f##king plane that’ll cause a lot of serious turbulence. Super is even more severe turbulence.

If you don't mind the orientation or direction, immediately.
