Description
This unit involves the skills and knowledge required to conduct an instrument approach using the VOR approach procedure. This includes beginning with a descent from a route Minimum Safe Altitude (MSA) or Lowest Safe Altitude (LSALT) in compliance with any altitude restrictions on a prescribed track to the Minimum Descent Altitude (MDA) applicable to the aircraft category; and conducting a published missed approach. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Select approach and determine applicable minima
  • 1.1 Instrument Approach and Landing (IAL) chart for the VHF omni-directional radio range (VOR) approach to be flown is selected
  • 1.2 IAL chart is reviewed and briefed in relation to directing entry to the approach; maintaining minimum altitude (LSALT or MSA) prior to approach entry; maintaining tracks, distances, timing and descent limitation for the approach
  • 1.3 Fuel availability and latest divert time procedures are enacted if required
2Monitor aid signal integrity
  • 2.1 VOR to be used for the selected approach is tuned and identified
  • 2.2 Warning flags and Course Deviation Indicators (CDI) indications are monitored throughout the approach to ensure signal integrity
3Conduct initial approach
  • 3.1 Altimeter is set to the appropriate QNH
  • 3.2 Inbound track at or above route MSA or LSALT is maintained in accordance with AIP, using the VOR
4Conduct holding pattern
  • 4.1 Holding pattern at or above LSALT or MSA is entered in accordance with the specified sector entry
  • 4.2 Holding pattern is performed is accordance with AIP, using the VOR
5Conduct instrument approach procedure
  • 5.1 Instrument approach is conducted in accordance with tolerances specified in AIP, using the VOR
  • 5.2 Landing runway is identified
  • 5.3 After establishing visual reference, a visual circling or runway approach is conducted for a landing on the selected runway, in accordance with AIP
6Conduct missed approach procedure
  • 6.1 Conditions requiring a missed approach are recognised and missed approach is initiated
  • 6.2 Aircraft is manoeuvred to Missed Approach Point (MAPt)
  • 6.3 Missed approach procedure is conducted in accordance with the IAL chart
  • 6.4 Obstacle clearance in IMC/simulated IMC is maintained
