       (4) The long side of the rectangle must be 3.5 m and other sides 1 m long.

       (5) The push-back vehicle parking position line marking must commence a minimum of 3 m from the nose of the aircraft with the reference code which the parking position is intended to serve.

       (6) If the push-back vehicle parking position line marking needs to be marked with an alignment line marking, the push-back vehicle parking position line is the primary marking.
