MAN: Modified DESIG1R?
Evening PPRUNE,
tonight at about 21:00 i witnessed a Pakistan 747-300 depart on a DESIG1R, it exercised the usual path (turn right at D3 MCT(345), turn right at XUMAT (083) to DESIG)....
the next departure was a Air Berlin 737-800 which seemed to take the same routing, but this time it continued way past XUMAT(345), thus leaving the turn to DESIG much later than usual...
so why was this?, i can only think of wake turbulence from the PIA 743?
hope MAN control can help
cheers

No idea why in this case. Unlikely to be due to vortex wake though, as there would have been at least 2 minutes between them at departure and the 747 would have had a pretty decent groundspeed (although very little climb rate probably!). Probably the sector had the 737 on radar headings then to separate against other traffic either inbound or setting up for a more northerly eastbound track? Like I said, just a guess.
