Description
This unit involves the skills and knowledge required to conduct a GPS/NPA instrument approach from route Lowest Safe Altitude (LSALT). This includes entering the GPS/NPA approach procedure in compliance with any altitude restrictions; tracking via the specified approach Way-point (WPT), descending in accordance with specified altitude limitations to a straight in or circling Minimum Descent Altitude (MDA), and performing a straight-in or circling approach or conducting a published missed approach if visual reference is not established by the Missed Approach Point (MAPt), using the GPS. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Select approach and determine applicable minima
- 1.1 The current Instrument Approach and Landing (IAL) chart for the GPS/NPA approach to be flown is selected
- 1.2 The entry to and conduct of the instrument approach and missed approach procedure is reviewed and briefed
- 1.3 The currency of the GPS receiver database is confirmed
- 1.4 The applicable meteorological minima of the approach for the aircraft performance category is determined
- 1.5 Fuel availability and holding or diversion action if visual reference is not established is reviewed and briefed
2Select, retrieve and activate approach from database
- 2.1 GPS approach for the appropriate runway from the GPS receiver navigation database is selected
- 2.2 Initial approach fix to be used to transition of the approach procedure is selected
- 2.3 Aerodrome altimeter subscale setting to obtain elevation or altitude (QNH) in the GPS receiver is entered, and approach is activated
- 2.4 Confidence check of tracks and distances between the approach Way-point (WPT) as calculated by the GPS receiver is performed
- 2.5 Course Deviation Indictors (CDI) are checked and selected to GPS as applicable
3Monitor GPS signal integrity
- 3.1 Receiver autonomous integrity monitoring (RAIM) is checked for availability on the approach
- 3.2 RAIM indications are monitored throughout the approach
4Conduct initial approach
- 4.1 Altimeter is set to appropriate QNH
- 4.2 Track to the initial approach WPT is maintained at or above route MSA or LSALT
5Conduct holding pattern
- 5.1 Automatic sequencing of the GPS is suspended
- 5.2 Published holding pattern is conducted at the appropriate initial approach WPT using the prescribed sector entry procedure
- 5.3 Automatic sequencing is resumed to continue the approach
6Conduct approach procedure
- 6.1 GPS/NPA instrument approach is conducted while descending on the specified track to each approach WPT
- 6.2 Approach altitude restrictions are complied with
- 6.3 GPS receiver transitions to approach mode is confirmed no later than the Final Approach Point (FAP), WPT or discontinue approach
- 6.4 Secondary navigation aid is utilised to maintain situational awareness
- 6.5 Descent to not below the MDA while tracking to the missed approach point is conducted within tolerances
- 6.6 Landing runway is identified
- 6.7 Runway or circling approach for a landing is conducted after visual reference is established
7Conduct missed approach procedure
- 7.1 Conditions requiring a missed approach are recognised and missed approach is initiated
- 7.2 Published missed approach procedure is executed if visual reference is not established before reaching the MAPt or RAIM
- 7.3 A missed approached is conducted on any other event specified in AIP or GPS operations manual
- 7.4 Aircraft is manoeuvred to Missed Approach Point (MAPt)
- 7.5 Missed approach mode is selected
- 7.6 Missed approach procedure is conducted in accordance with the IAL chart
- 7.7 GPS receiver is configured to conduct another approach or to hold or divert as required
- 7.8 Obstacle clearance in IMC/simulated IMC is maintained
