I caught this last night. AA 254 (757) from OGG goes around at LAX at 11:50ish of this MP3. You can also hear atc whistling Pirates of the Caribbean in the background. Made me laugh after a long day of teaching!!
Sorry about the length, but I am still trying to figure out how to use the Audacity thing to shorten the clips.
Thanks

jajajajajaj.... Nice...
Thank You.... :roll:

Hear the Pirates tune at the beginning? The tune switches around throughout the MP3!! LoL
Thanks

why is a 757-200 from AA using the "heavy" designator? i thought only the -300s and some very rare variants (ATA, etc) had "heavy" 75's.
255,000 MGTOW

A lot of facilities have issued directives that require controllers to treat any B757 as heavy. Such is the case at Boston, Los Angeles, and many others.

yeah, i have heard that many facilities "treat" the 757s as heavies in terms of spacing, but I was not aware of them actually being given the heavy callsign. If you look for instance at the other 757s going into LAX, none of the other ones have the H in the equipment like the one on this go around did (via flightaware)
-
some 752's are heavy's
-
Must'a had the family at Disneyland the day before!
-
Some of the B752's are heavy's because they added wingtips and extra fuel tanks in the back . This caused the weight to be over 255,000 lbs.
-
The Biggest Loser contestants were on this flight putting the aircraft over 255,000 lbs that's why "Heavy" was attached to the callsign. :lol:

I was on a 737 a few weeks ago and it should of been called heavy.... The most fat people I gad ever seen!!

I know you and the other guy are kidding, but the distinction is MGTOW (Max Gross Take-Off Weight), not the actual weight of the aircraft at any given moment. If the plane CAN weigh more than 255k then it's "heavy," if it can not, then it is not called "heavy."
As mentioned, some facilities treat 757's as a heavy, as opposed to the next distinction down, in order to provide adequate spacing due to the unique and extreme wake turbulence it causes.

Right on the money Pilot3033.

I know it is 255,000. I heard on Lax freq them calling some 757's heavy, usually the 300's from continental and northwest. 50% of the time they call the 200's heavy. It sounds like they are getting use to the change.

...I didn't hear anything out of the ordinary...

I vaguely recall some 15 years or so ago the FAA got a bunch of complaints of turbulence from planes following behind a 757. They decided the 757 wing generated stronger than "normal" wingtip vorticies than would be expected for the weight. ATC was instructed to compensate by treating all 757's as heavy even if they wouldn't otherwise require the designation.
Memory is vague as it really didn't affect me one way or the other.

It boils down to this. All 753's are heavies. Some 752's are heavies due to extra fuel tanks and being rated for a higher MTOW then most 752's. Even the 752's that are not heavies have special separation rules that apply to them on final, but it's not as simple as treating them as heavies.
-
I was at KSNA yesterday and they called an American 757 Heavy and the US Air 757 regular. It must be the added tanks and winglets also. The Cactus didnt have the winglets.
-
We now have to treat all 757 200 series as heavies. But if you ask the pilot and they state that they are not a heavy then you can treat them as a regular 757.

At KLAX AAL is the only carrier with the exception of an occasional AWE that have H/B752/_
