Surveillance

Lateral

5nm

  • Enroute positions

3nm

  • ADC positions
  • TCU positions

Note

The 3nm standard may be used by Enroute controllers providing top-down to a TCU, only if a seperate air display is used for the TCU position. Otherwise, 5nm standard must be used in the TCU

Sequencing

Enroute to TCU

Enroute must aim to have 2 minute spacing between two arrivals at the same Feeder Fix for the same runway.

This distance may be reduced to an absolute minimum of 10nm.

This includes aircraft inbound through nearby Feeder Fixes (eg: LIZZI and BOYSE at YMML) when specified by Local Instructions.

TCU to ADC

TCU must aim to have 2-3 minute spacing between two arrivals for the same runway.

This distance may be reduced to an absolute minimum of 5nm.

Vertical

500ft

  • Between an IFR and VFR aircraft where;
    • Both aircraft have Light Wake Turbulence Category; and
    • Both aircraft are at or below 10,000ft; and
    • Traffic information is passed to the IFR aircraft

1000ft

  • Between any aircraft at or below F290
  • Between 2 RVSM-approved aircraft at or below F410

2000ft

  • Between any aircraft that is experiencing Severe Turbulence at any level
  • Between all aircraft above F410
  • Between F290 and F410 inclusive;
    • When at least 1 aircraft is not RVSM-approved
    • Between military formation aircraft, regardless of RVSM status

3000ft

  • When at least one aircraft is supersonic
