This indicator has North at the top of the dial, and a
rotating aircraft symbol that rotates in sympathy with the heading of the
aircraft. The deviation bar is placed around the aircraft symbol, in exactly
the same relative position that the selected track is in relation to the
aircraft. If you draw a sketch using the information given in the question you
will see that in this case the selected track is behind the aircraft, and that
is where the bar will be placed on the dial.
