Re: DP/SIDs
Actually. . .
SIDs became DPs, then were back to SIDs after the ICAO had some beef about changing the abbreviation. This transition all happened between 02-04.
This was a big topic during CTI, but I'll have to search and rummage through a number of papers and books to find the exact dates SID became a DP, and a DP became a SID again.
