There is indeed a difference in pressure on top and on the bottom of a wing but the main function of the wing is to accelerate the air it passes through towards the ground (like a ceiling fan's blade does). The air goes down, the plane goes up just like Newton intended. The block of air going down is only as wide as the wing - the air to the left and to the right of the wing is not affected. At the transition you are adding a rotation, hence the wingtip vortices.
Super cool video!
Minutes after a big jet had landed you would hear the noise of the vortices reaching the ground - they sounded like someone whipping a long stick to and fro.
This was when Concorde was still flying - that would set most of the car alarms off from the engine roar and the dirty brown trail of partially burnt fuel was a sight to behold!
It's awesome. Apparently there are quite a few calls to various bodies either complaining about or reporting unidentifiable noises in the sky.
It's pretty much the only positive of having a busy international airport so close to the centre of the city (obviously it's been a lot quiter over the last 14-15 months).
A cheap diode laser would get the job done.
This story is fairly interesting:
The tower must have been watching pretty closely because they notified other traffic within about 2 seconds before I called in or gained altitude.
Is it the weight of aircraft that contributes to the wake turbulence or the physical size? Presumably these usually correlate pretty well but just asking for clarity…
It makes me want a fog machine too. My daughter is still a little young to appreciate the science but I bet she’d have fun playing with fog!
