you can see the flap vortex on my DC-9 landing. It was my first ever airliner flight and I was wondering how lucky I would have to be to get to see them. Yet they showed up!
@82648947 Actually they are termed wingtip vortices because they form off the wing tip. AND WINGTIP vortices are not visible unless there is a cloud or something to show the movement of air. Ive been studying aviation for three years. Shut up you're a fucking moron
@gypsykingg ..you read wikipedia too much. I quote for your education from the Boeing web site " Commercial airplanes with flaps extended produce multiple trailing vortices that remain distinct for some distance behind the airplane". You will see in this video that vortices also come off the traliling edges of the flaps on this aircraft. Also study the physics of vortex production, cloud is NOT required for them to be visible as you claim.
@82648947 Yes I did all my ground school and earned my commercial license for wiki. You need to study the physics of the formation of vortices. I know how they're formed. Because I need to because they can be very dangerous
@gypsykingg ..Good, I also know how they are formed. As long as you understand there are multiple vortices formed on wings with flaps deployed and spoilerons in motion, and not only from the wingtips, all will be okay.
@gypsykingg ..I suggest you watch the video "HD Wing Condensation & Vortices " and you will see where they usually form..the outer trailing edge of the flaps. You will also notice no clouds present to "show the movement of air" as you claim is necessary.
No. You *don't* need a cloud to see a wingtip vortex.
A wingtip vortex becomes visible when the temperature within it drops below the local dew point. A vortex becomes visible when liquid water or ice droplets form in its core.
While a dark cloud in the background can increase the contrast - and make vortices more evident - they aren't necessary.
Good engineering video, visual representation of how airflow around an airfoil shape and the air conditioning effects of air expandings on top of the wing and cooling the air causing watervapour to condense and fog up. very nice for you to capture this video, The humidity level have to be perfect for this visual phenomenon to occur. Once I captured a unique shot like this on the 777, too bad that CD got corrupted while burning..
this happened to me to i was in 737 to omaha and i look out window and see this i was like holy crap were gonna crash but not outloud and i was joking it was cloudy, rainy and windy on decesend
you can't see vortices, the strings of water vapor you see in the video is only the core of the vortices.

The panel between the two flaps is fluttering like it wants to deploy as a spoiler. WTF.

@lifeson30 It's called a high speed aileron. It helps the aircraft turn.

those are not vortices, that's due to the high pressure above the wing become low pressure very quickly which causes the air to condense

@gypsykingg...No, they ARE termed vortices!
