Co-ordination between en-route controllers.
Wondered about this last week when the below exchanges happened a couple of times.
Situation; currently being vectored en-route flying heading 160
"ABC own navigation direct CLIPY, contact London Control on xxx.xxx"
change freq
"London Control ABC FL90 direct CLIPY"
"ABC roger turn left heading 160"
This makes me wonder what coordination goes on between the two en-route controllers, as I would have thought the first one would arrange with the next one for the direct routing into their sector, and it seems strange to go straight back to the previous vector on transfer. Would reasons would often be behind this?
