Conduct a 2D global navigation satellite system non-precision instrument approach

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria



Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.


Select approach and determine applicable minima


Current instrument approach and landing (IAL) chart for GNSS/NPA approach to be flown is selected


Entry to and conduct of instrument approach and missed approach procedure are reviewed and briefed to flight crew


Currency of GNSS receiver database is confirmed


Applicable meteorological minima of approach for aircraft performance category is determined


Fuel availability and holding or diversion action if visual reference is not established, is reviewed and briefed to flight crew


Select, retrieve and activate approach from database


GNSS approach for appropriate runway from GNSS receiver navigation database, is selected


Initial approach fix to be used to transition approach procedure is selected


Aerodrome altimeter subscale setting to obtain elevation or altitude (QNH) in GNSS receiver is entered, and approach is activated


Confidence check of tracks and distances between approach way-point (WPT) as calculated by the GNSS receiver, is performed


Course deviation indictors (CDI) are checked and selected to GNSS as required


Monitor GNSS signal integrity


Receiver autonomous integrity monitoring (RAIM) is checked for availability on the approach


RAIM indications are monitored throughout the approach


Conduct initial approach


Altimeter is set to appropriate QNH


Track to initial approach WPT is maintained at or above route minimum safe altitude (MSA) or lowest safe altitude (LSALT)


Conduct holding pattern


Automatic sequencing of GNSS is suspended


Published holding pattern is conducted at appropriate initial approach WPT using prescribed sector entry procedure


Automatic sequencing is resumed to continue approach


Conduct approach procedure


GNSS/NPA instrument approach is conducted while descending on specified track to each approach WPT


Approach altitude restrictions are complied with


GNSS receiver transitions to approach mode is confirmed no later than the final approach point (FAP), WPT or discontinue approach


Secondary navigation aid is utilised to maintain situational awareness


Descent to not below the minimum descent altitude (MDA) while tracking to the missed approach point, is conducted within tolerances


Landing runway is identified


Runway or circling approach for landing is conducted after visual reference is established


Conduct missed approach procedure


Conditions requiring a missed approach are recognised and missed approach is initiated


Published missed approach procedure is executed if visual reference is not established before reaching the MAPt or RAIM


Missed approached is conducted on any other event specified in aeronautical information publication (AIP) or GNSS operations manual


Aircraft is manoeuvred to MAPt


Missed approach mode is selected


Missed approach procedure is conducted in accordance with IAL chart


GNSS receiver is configured to conduct another approach or to hold or divert as required


Obstacle clearance in instrument meteorological conditions (IMC) is maintained
