Im looking for guidance on a problem i am having. I have seen other people give commands for a plane to go to the runway. So it looks like this: Delta 1234 pushback approved expect runway 31 at taxiway B via A B. When I do this all it picks up is Delta 1234 pushback approved expect runway 31 and does not finish the command. What am I doing wrong or is there something that I am missing. Any help will be appeciative.
