aircraft tobe identified,with aminimum lateral displacement of 1000 ft or
300m;
• if strictly necessary for identification,move closerwhilemaintaining a
generally parallel course, but never closer than200m;
• if identified as friendly,make the appropriate signal toproceed from a
position slightly ahead, by a climbing turn of 90degrees toport away from
the intercepted aircraft, if permissible, consideringother air traffic.
