Photo of the Day

Today I was flying to Lyon on a Lufthansa 737. During landing in a very moist air I quickly captured the following photos.



It shows wake vortices of the airplane. Normally, you see them at the actual wingtip. Here they come from the extended Fowler flap. They are a consequence of the overpressure below the wing and the low pressure above the wing balancing out around the tip. Because the airplane moves forward, the vortices look like a corkscrew .Imagine how powerful this work is his are at the actual wingtip! You don't want to accidentally fly into these with a small plane.
 
Comments:
Isn't this one of the reasons to install winglets?
 
these are on the flaps, you can't install winglets there. But similar vortexes happen on the wingtip, and yes, there winglets can be used to reduce/avoid these.
