ADAWS and the type 42 have had this problem for years and it won't be resolved until (hopefully will be resolved with) the introduction of the T45. The GPS is not locked into the tactical plot, for some bizarre reason. Working before with a T42 we gave positioning in Lat/Long that was crossed into grid for the plot before being converted back to Lat/Long for the targeting computer, with ERRORS. There is training/competence issues here with cross referencing plots but when there are lives at risk and the problem is known how can this be a red herring. Nobody knows if the bag held the ship on radar or was relying upon position reports passed from the ship. T42's do not physically jump miles! Shame really, t'would be a huge saving in fuel bills!
What the Bag was doing? Thats a BOI thing I'm afraid, none of us have enough info to speculate on services provided and I'm sure we all agree that the aircraft captain would have kept a close eye on the plot as well.
The Lynx MK 8 can carry three people and full fuel even in the Gulf. This idea that it has the legs of a wasp is c&*p. The only issue that could cause a problem is single engine recovery to the deck, but hey that affects all helos in the area.
