Incident at Gander Oceanic


1996-06-21: N805DE (MD11) and N763DL (L1011) progressed 50W and 40W within ten minutes. When N763DL, reported by 49N/30W longitudinal separation was reduced to 7 minutes when 10 minutes is the standard. The controller identified the loss of separation and Preswick was advised, who had DAL38 reduce their Mach speed to restore separation to 10 minutes. It could not be determined why the 10 minutes separation which was maintained past the two previous position points, was reduced to 7 minutes at 49N/30W.
