Re: 747 180 degree turn on runway after backtrack

The typical technique is to track the centreline and then "diverge" sideways towards the edge until the pilot on the outer side is at the "turning point" (on the A330, this point takes the "outer pilot" well over the runway edge since the nose gear is rather far back), ...

Re: Fedex callsigns into Indy: all 16XX

Many carriers have patterns like this. At my carrier, the first flight number digit indicates the region. Also, odd flight numbers are westbound and even numbers eastbound.

It isn't really that confusing most of the time. With a bit of practice, you learn to discriminate between all those numbers.
