hi tic
this is probably due to the fact that the FPLs that we have at any given time may or may not be true. The only way that we can ensure that you end up flying through our airspace without making any unexpected turns that endanger others or surprise us is by reading out, long-hand, the route that we're expecting you to fly. Sounds strange, I know, but we can't rely on the FPLs submitted.
If you're wondering why we don't necessarily have the right FPL; it's because some operators don't file at all, relying on our good nature to electronically input them on their behalf, or the FPLs are incorrectly processed after multiple plans have been put into the AFTN. Sometimes, we even find that the FPL carried in the cockpit bears no resemblence to the only one we've received in the centre.
Anyway, my hope is that you get a good service regardless. Have a good one.
