Description
This unit involves the skills and knowledge required to conduct an instrument approach using the ILS approach procedure. This includes beginning with a descent from a route Minimum Safe Altitude (MSA) or Lowest Safe Altitude (LSALT) in accordance with any altitude restrictions; intercepting track on the Localizer (LLZ) using locating/marker beacons or Distance Measuring Equipment (DME/GPS); fixing a position on the LLZ track; descending by reference to the Glideslope (GS) to the Decision Altitude (DA); landing or conducting a published missed approach. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Select and prepare for the approach
- 1.1 The current Instrument Approach and Landing (IAL) chart for the Instrument Landing System (ILS) approach to be flown is selected
- 1.2 The instrument approach and missed approach procedure is planned
- 1.3 Direct entry to the approach is reviewed, briefed and evaluated
- 1.4 Entry via holding pattern is reviewed, briefed and evaluated
- 1.5 Minimum altitude, LSALT or MSA prior to approach entry is reviewed and briefed in relation to tracks, distances, timing and descent limitations
- 1.6 The applicable approach minima for the aircraft performance category and runway to be used is selected
- 1.7 Pressure error correction to DA is selected
- 1.8 The holding or diversion action if visual reference is not established is reviewed and briefed
- 1.9 Fuel availability and latest divert time is selected if required
- 1.10 Aircraft systems are configured for approach
- 1.11 Altimeter is set to appropriate QNH
2Monitor aid signal integrity
- 2.1 The ILS to be used for the selected approach is tuned and identified
- 2.2 The warning flags and Course Deviation Indicators (CDI) for both LLZ and glide slope throughout the approach is monitored to ensure signal integrity
- 2.3 Locator beacons for the approach are tuned and identified
- 2.4 Marker beacon/s are tested and monitored for visual and aural indications during approach
- 2.5 DME is tuned and identified or GPS configured for ILS approach if applicable
- 2.6 DME/GPS is monitored for distance indications during applicable approach
3Conduct holding pattern
- 3.1 Holding pattern at or above LSALT or MSA is entered in accordance with the specified sector entry
- 3.2 Holding pattern is performed in accordance with instructions in AIP, using the LLZ and any other navigation aids
- 3.3 Holding fix is identified
4Conduct approach procedure
- 4.1 Aircraft is tracked to the initial approach fix using appropriate tracking aids or radar vectors at or above route MSA or LSALT to intercept the LLZ track
- 4.2 ILS approach is conducted from the initial approach fix with tracking by reference to the LLZ and descent by reference to the glidepath
- 4.3 Marker beacons, DME/GPS or approved alternative fix are used to provide distance indications
- 4.4 At least one specified altitude check on glide slope is performed
- 4.5 Continued descent on glide slope to the DA is performed in accordance AIP
- 4.6 Landing runway is identified
- 4.7 Runway or circling approach for a landing is conducted in accordance with AIP after visual reference is established
5Conduct missed approach procedure
- 5.1 Conditions requiring a missed approach are recognised and missed approach is initiated
- 5.2 Aircraft is manoeuvred to Missed Approach Point (MAPt)
- 5.3 Missed approach procedure is conducted in accordance with the IAL chart
- 5.4 Obstacle clearance in IMC/simulated IMC is maintained
