Description
This unit involves the skills and knowledge required to conduct a DME or GPS Arrival procedure from the Lowest Safe Altitude (LSALT), within a specified sector or on a specified track. This includes descending not below the distance/altitude descent steps specified for the procedure to the Minimum Descent Altitude (MDA) applicable to the aircraft category; conducting a published missed approach if visual reference is not achieved by the Missed Approach Point (MAPt); using Non-directional Beacon (NDB) or VHF Omni-directional Radio Range (VOR) for tracking and DME or GPS to provide distance indications. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Select and prepare for approach
  • 1.1 The current Instrument Approach and Landing (IAL) chart for the DME/GPS approach to be flown is selected
  • 1.2 The instrument approach and missed approach procedure is planned
  • 1.3 MDA is determined
  • 1.4 Sector entry to the approach and holding pattern is selected, reviewed and briefed as appropriate
  • 1.5 Minimum altitude, LSALT or Minimum Safe Altitude (MSA) prior to approach entry is reviewed and briefed in relation to tracks, distances and descent limitations
  • 1.6 The applicable approach minima for the aircraft performance category and runway to be used is selected
  • 1.7 The holding or diversion action if visual reference is not established is reviewed and briefed
  • 1.8 Fuel availability and latest divert time is selected if required
  • 1.9 Altimeter is set to appropriate QNH
2Use appropriate tracking aid and distance information and monitor aid signal integrity
  • 2.1 DME is tuned and identified
  • 2.2 The reference Way-point (WPT) for GPS to be used for tracking inbound is selected
  • 2.3 The distance indication is checked
  • 2.4 Approach aid is monitored throughout the approach to ensure signal integrity
  • 2.5 DME or GPS is used to provide distance indications for descent via the distance/altitude steps of the approach
  • 2.6 Availability of receiver autonomous integrity monitoring (RAIM) is ensured before descending below LSALT or MSA
3Conduct approach procedure
  • 3.1 Initial approach is conducted not below the specified limiting altitude for the distance/altitude descent steps
  • 3.2 Arrival procedure is conducted while descending on the specified track or sector in accordance with AIP
  • 3.3 Landing runway is identified
  • 3.4 Runway or circling approach for a landing is conducted after visual reference is established
4Conduct missed approach procedure
  • 4.1 Conditions requiring a missed approach are recognised and missed approach is initiated
  • 4.2 Aircraft is manoeuvred to Missed Approach Point (MAPt)
  • 4.3 Missed approach procedure is conducted in accordance with the IAL chart
  • 4.4 Obstacle clearance in IMC/simulated IMC is maintained
