tell me the one aircraft that is in this category even though it does not meet the weight requirments and why??
Not quite correct.
There are a few aircraft that are classed as 'Upper Medium' at airports in the UK, Heathrow being one. The 757 and VC10 are in this category although technically they are actually in the medium category, not heavy. CAP 493 Manual of Air Traffic Services Part 1 refers.

My bad - didnt even consider the UK - the question comes from a FAA ATP exam - and is specifically aimed at the 757s wake turbulence charachteristics
I'll remember to be clearer next time :roll:
Funny - didnt notice the Queen of the skies using "heavy" going into Nellis

IIRC I first heard the term "heavy" on ATC when the 747s started to appear at Heathrow. Was never used at the same time for DC-8 and 707. So I suspect that there must have been some rule implemented to make sure that separation was increased on final approach. And in those days there was often an additional verbal warning about "being aware of wake turbulence from the one in front"

From the FAA so Im told - and I believe EVERYTHING the FAA tells me.
Ian -the first time I heard it used was in 1978 dead-heading from LGW-ATL on a DC10 and I specifically asked the TIA crew what
that was all about - and was told it had just been instituted by the FAA - but hey what would I know
Not in the mood - its been a really Sh*tty night at work and I'm tired of trying to be helpful
