I will begin by answering the first part of your question, regarding manufacturers and air traffic control. With respect to air traffic control, we've just published the regulations in January 2008, which includes airports and air traffic control. The process has therefore begun.
With respect to aircraft manufacturers, the regulations will not come into effect for about another two years.
With respect to the deadline of September 2008, Mr. Preuss can provide you with further details on that.
