AMEX,
I don´t know where you fly, where I fly (mostly europe) I´ll be told either by the plate or ATC how quick to fly (yeah I´m the captain, still I like the Idea of complying to instructions). So there is not to much room for straying from speed. (especially not at airports that are served with the heavies -the 57 aside)
The seperation we get here is usually 5 or 6 nm behind heavies (depend on your own weight class)
I had 2 closer shapes with wakes, one in a CJ2 behind a 757 and one in a KingAir behind a Fokker 50. Both have been in weather when by the book, you would not have expected it.
Still I´d like the big fellows at least tell us if they fly high on the GS. I usually fly high as well.
BTW, anyone else noticed that newbies have a real trouble to fliy exactly one dot off whilst they are really good on flying on the glide? Maybe I was the same, but I don´t recall.
BelArgUSA: happy retirement! Wish I would be short before it as well...
