Aircraft taking off behind it need to wait for the wake to pass....Longer time needed for Heavy aircraft or aircraft with large wake due to wing designOriginally Posted by Tower Air
747,Dc-10, MD-11, A340, A330, A300, L-1011 and.......757 wing is horrible with the wingtip wake vortices's so that is also on the list.
The three most common expressions in aviation are, "Why is it doing that?", "Where are we?" and "Oh Crap".
the takeoff weight of the aircraft is over 250,000 lb. in addition, the wake turbulence behind some airplanes (757 namely) that they are just assigned a 'heavy designation."
there are more rules to wake turblence, send me a PM if you want more clarification.
it is mathematically impossible for either hummingbirds, or helicopters to fly. fortunately, neither are aware of this.
yeah, basically 200,000/+lbs but usually also the controller will add 'caution wake turbulence from the NWA 747 . . . .'

A 757 is not referred to as heavy on the radio,* but for wake turbulence separation standards, it's treated as a heavy. And, yes, controllers will say something like 'caution wake turbulence, you're 6 in trail of a 757,' when they otherwise wouldn't say that you're 6 in trail of, say, an A320. Heavy goes on any aircraft with an MTOW over 250,000lbs.
*ATA's 752s are certified with an MTOW of 255k, and, thus, are heavies.
This topic was discussed on some of the Aussie forums I am a member of, they might be of interest 8)

Not just he 757, because airlines like BA use RB211's on their 767's and 747's!the wake turbulence behind some airplanes (757 namely) that they are just assigned a 'heavy designation."
At MDW The word "Heavy" is frequently used on all 757-200 aircraft at that airport (ATA). I have always heard a 757-300 refered to as "Heavy" no matter where what airport you are at.
Also you might catch a Mexicana 757-200 pilot slip and use it at an airport.

a 757-300 is over the weight limit and therefore is "heavy"
Overheard on JFK TOWER - S Turns are fine, U-Turns are bad....
BMI at IAD and Icelandair at BWI use(d) "Heavy" with their callsign.
Both were 757s.

When it takes a 12 pack to make her look 'good' that is considered a HEAVY ;)
