Follow-up Question: “Would it be possible to do a follow up presentation for the next stakeholder meeting taking an actual real example of a flowgate constraint and ATC interface calculation and show what happens in the model runs as it goes from several months out to current real time? I think that would be very illustrative and now that we understand the process much better this would give us a better picture of what the implementation looks like. “ Topic has been held to be addressed at the Face to Face meeting scheduled for May 24, 2012
