               destination %       land level at 0, headed northwest 
               destination fix     exit level at 5 thousand 
               separation          different altitude or 3 miles 
               fuel                jets 15 minutes, props 21 minutes

               Aircraft burn fuel while waiting to take off. 
               Landing aircraft have an implicit hold (H) command. 
               Commands are executed upon detection of last needed 
                 keystroke.  (i.e., ENTER is not required). 
               Upper or lower case input accepted. 
           
          Notes: 
           
              The % and # commands could be called "clear to approach."
              Missed approaches are possible.  After an xA0 command, the
              aircraft will no longer accept commands.  However, if it
              crosses the wrong airport it will be returned to altitude 1
              instead of landing and will once again accept commands. Turns
              take effect during the NEXT 15 second interval, not
              immediately.
