Not really frustration, Scott, consider it 'eagerness' to get both sides of the microphone understanding each other's problems. We had a fair bit of success a while back with the 'LGW arrivals' thread in learning such (not so much with 'LGW departures') and I hope this will do the same with 'descents'. In conversation in the pub last night it seems there may be more queries from UK pilots on US descent profiles which I hope they will raise here (my horizons are short-haul Europe only).
PPR (3 above) highlights discrepancies on expected descent profiles which should be explored too?
