I started in 1988 and it was in there then. Nobody knew how bad the 757
was at that time, the crashes were just starting to pile up. They changed
the 757 to basically a heavy in the 90's.

What planes, or how heavy does a plane need to be to get the heavy
designation?

What do they call the ones just below that, and do they issue wake warnings
behind them?

Thanks.
