What Constitutes A "Heavy"?

Fri Dec 21, 2001 8:03 am

I always hear the term "Heavy" used in reference to planes like the 747... Why (Besides the size) is it considered a "Heavy", and what other a/c are in the same class?

To simplify the matter, all widebodies, plus 757's.

Ben88, I am not sure about the 753, but the 752 is technically considered a heavy to ATC even though it does not weigh the heavy weight. But, I have heard through the grapevine that ATAs 757s are considered heavies. Can anyone confirm?

All B-757s are classified as "heavy" by ATC. So is the Concorde, believe it or not.

The Concorde doesn't need to be classified a heavy anyway, it automatically gets priority for its fuel situation.

I've listened to ATC before and I didn't think that 757s were called heavys. Also something that I noticed... the 763 is called a heavy but not a 762.

Am I loosing my mind?

The reason for the heavy callsign is not for fuel, but for wake turbulence separation.

Heavys have to have 5 miles cleared behind them, 757-200's 4 miles, and regular airliners 3.

In the US a heavy qualifies for an airplane that has an MGTOW of greater tahn 255,000 pounds. Note that it does not have to actually weigh that...just be able to weigh that.
