The main reason for the post is to ask pilots for some help when this happens. If you can see early on that a turn may be neccessary, let us know asap. Our best policy in these situations is to go for just vertical separation, radar headings with 'at your discretion' descents do not work when one wants to manouvre towards another. Let us know exactly what heading you need, and if you can go around either way, give us the choice of the 2 headings needed. We then can choose quickly the best way for the plan ahead.
What you seem to be asking for, 5mb, is for crews to share their plans with you sooner rather than later, so that you can fit their weather planning in with your air traffic management planning. I think that's an excellent suggestion.
But can you understand my frustration at reading that in the light of your responses in
this thread when I asked that
you share your plan with
us?
