Elements and Performance Criteria

1. Select and prepare for the approach
2. Current instrument approach and landing (IAL) chart for the ILS approach to be flown is selected
3. Navigation system validity and receiver autonomous integrity monitoring (RAIM)/space based augmentation system (SBAS) checks are conducted as required
4. Instrument approach and missed approach procedure is planned and self-briefed or briefed to flight crew as required
5. Direct entry to the approach is reviewed, briefed to flight crew and evaluated
6. Entry via holding pattern is reviewed, briefed to flight crew and evaluated
7. 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, timing and descent limitations
8. Applicable approach minima for aircraft performance category and runway to be used is selected
9. Pressure error correction for decision altitude (DA) is selected
10. Holding or diversion action if visual reference is not established, is reviewed and briefed
    • Fuel availability and latest divert time is selected as required
    • Aircraft systems are configured for approach and altimeter is set to appropriate QNH
11. Monitor aid signal integrity
12. ILS to be used for selected approach is tuned and identified
13. Warning flags and course deviation indicators (CDI) for localiser (LLZ) and glide slope is monitored throughout the approach to ensure signal integrity
14. Locator beacons for approach are tuned and identified
15. Marker beacon/s are tested and monitored for visual and aural indications during approach
16. Distance measuring equipment (DME) is tuned and identified or global navigation satellite system (GNSS) is configured for ILS approach as required
17. DME/GNSS is monitored for distance indications during applicable approach

20. Holding fix is identified and aircraft is manoeuvred to appropriate sector entry position
21. Conduct holding pattern
22. Holding pattern at or above LSALT or MSA is entered in accordance with specified sector entry
23. Holding pattern is performed in accordance with instructions in aeronautical information publication (AIP), using the LLZ and any other navigation aids
24. Conduct approach procedure
25. Aircraft is tracked to initial approach fix using appropriate tracking aids or radar vectors at or above route MSA or LSALT, to intercept the LLZ track
26. ILS approach is conducted from initial approach fix with tracking by reference to LLZ and descent by reference to glide path
27. Marker beacons, DME/GNSS or approved alternative fix are used to provide distance indications
28. Specified altitude check on glide slope is performed
29. Continued descent on glide slope to the DA is performed in accordance with AIP
30. Landing runway is identified
31. Runway or circling approach for a landing is conducted in accordance with AIP after visual reference is established
