Expect to be put on radar vectors, expect to be allocated a level other than your requested one, expect a small delay (traffic dependant there might be no delay) to your joining clearance.
Many thanks again for your tips and comments!
I have also learnt something new about priority between IFR flights in CAS.
As always, I will be prepared to hold/ have a level other than the planned onel/ be vectored around and so on. Generally speaking I will be ready for different scenarios, and different course of actions on my side... After all your comments, I'll be much more prepared to respond to what it could happen.
As you lovely ATCOs might know
, now I have a good essential "picture" of the traffic, the area, the use of the airspace and of my flight within the chosen route.
I will let you know how I will get on...!
(by the way, the flight is being planned for next week!)
Many thanks indeed for all your help!
Cheers.
