Elements and Performance Criteria

1. Select and prepare for approach
   • Current instrument approach and landing (IAL) chart for the DME/GNSS approach to be flown is selected
2. Instrument approach and missed approach procedures are planned
3. Minimum descent altitude (MDA) is determined
4. Sector entry to approach and holding pattern is selected, reviewed and briefed to flight crew as appropriate
5. Minimum altitude, lowest safe altitude (LSALT) or minimum safe altitude (MSA) prior to approach entry, is reviewed and briefed to flight crew in relation to tracks, distances and descent limitations
6. Applicable approach minima for aircraft performance category and runway to be used, is selected
7. Holding or diversion action if visual reference is not established, is reviewed and briefed
8. Fuel availability and latest divert time is selected as required
9. Altimeter is set to appropriate QNH
10. Use appropriate tracking aid and distance information, and monitor aid signal integrity
    • DME is tuned and identified
11. Reference way-point (WPT) for GNSS to be used for tracking inbound, is selected
12. Distance indication is checked
13. Approach aid is monitored throughout approach to ensure signal integrity
14. DME or GNSS is used to provide distance indications for descent via the distance/altitude steps of the approach
15. Availability of receiver autonomous integrity monitoring (RAIM) is ensured before descending below LSALT or MSA
16. Conduct approach procedure
    • Initial approach is conducted not below the specified limiting altitude for the distance/altitude descent steps
17. Arrival procedure is conducted while descending on the specified track or sector in accordance with aeronautical information publication (AIP) requirements
18. Landing runway is identified
19. Runway or circling approach for a landing is conducted after visual reference is established
20. Conduct missed approach procedure
    • Conditions requiring a missed approach are recognised and missed approach is initiated
21. Aircraft is manoeuvred to missed approach point (MAPt)
22. Missed approach procedure is conducted in accordance with the IAL chart
23. Obstacle clearance in instrument meteorological IMC is maintained

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.
