i mean if they didn't consider lost com u would only recieve your SID clearance and then any further onward clearance as you proceed.
That happens to me often enough too!
Like CJ driver, I think UK ATC (and it does seem to be UK in particular) largely ignores the ATC clearance as a plan for comm failure purposes. Mostly, air traffic management seems to be a tactical exercise with an implicit assumption that tactical instructions can continue to be issued when necessary, i.e. ignoring the comms failure scenario. It's not what ICAO had in mind when ATC was invented, but it seems to work without major incidents.
