Air Crew must use ICAO defined format for entry of the aircraft identification.
 - To ensure that the performance of systems based on SSR frequencies (including airborne TCAS units and SSR radars) is not compromised, TCAS should be selected when approaching the holding point. It should then be deselected after vacating the runway.
- For aircraft taxiing without flight plan, Mode A code 2000 should be selected.
