Perform global positioning system (GPS)_non-precision approach (NPA)

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

Reference books for 'Perform global positioning system (GPS)_non-precision approach (NPA)' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to for every purchase, so go nuts :)

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
