Scott, what you say is undoubtedly true, but I don't think it's confined to ACARS clearances. Just because I read back a clearance correctly over the RT doesn't mean that it's what I've put in the box, unfortunately......
And I do think you Yanks could improve the layout of your PDCs a bit, the squawk code is awfully hard to find, buried in amongst a whole bunch of other 4 digit numbers. The number of times I've tried to squawk my STD....
BTW, did I read one of the other posts above correctly? Are we actually going to be able to acknowledge the PDC electronically at LHR, without having to read it back, have it acknowledged, acknowledge the acknowledgement etc. Good heavens, such sensible thinking, what is the world coming to? But gadzooks man, we don't do things that way in the UK, next thing we know you'll be allowed to clear us for the ILS without first wasting RT time by clearing us for the loc, us reporting established on the loc, you clearing us down the slope, us acknowledging that clearance etc etc.....
