PBN Deployment – New Zealand Domestic Airspace

CAA PBN ForumNovember 18 2009Auckland

Background Drivers

• Modern FMS• Ground aids reaching end of life• Operational efficiency• Environmental

• ICAO• IATA

70 % rule

• FAA experience.

• Less than 70% users able to use – don’t implement

• More than 70% users able to use – implement • and withdraw conventional

In the beginning

• Establish RNAV as the default language/method of navigation and ATM

• at AA, WN and CH– 1/. RNAV STAR – 2/. RNAV SID – 3/. RNAV En-route between– 4/. RNAV approach as supplement to ILS

Followed by

• Establishing RNAV as default language/method of navigation and ATM

• at all airports with regional control towers– 1/. HN, RO, TG– 2/. NV, DN, WP– 3/. NS, WB– 4/. OH, PM, NP– 5/. NR, GS

Ideal roll out – ATC perspective

• Airport specific - implement as a package

• RNAV STAR• RNAV Approach • RNAV SID • Separation charts to enable management

• Staff training

Current anomalies/difficulties

• Some regional airports have parts of the package.

• Result of nav aids reaching end of life.

• Mixed fleet equipage.

• Complex lateral separations • Mixed messages.

Existing PBN procedures

• RNP10 (RNAV 10) in OCA

• RNP4 Trans-Tasman

• RNAV Enroute

• RNAV SIDs and STARs

• RNAV(GNSS) 57 locations

• APV @ 16 runways

• RNP AR @ Queenstown

• RNP AR @ RO, AA, WN, CH coming

So what’s to come

• Establish/confirm the Regional PBN Plan

• Initial scoping meeting – July 09• ATC planning meeting - 5,6,7,8 Oct 09

• Feedback from regional CCs• Ongoing coordination with users.• User meeting 1 Dec 09 • Generic Tower Model established (Feb 2010)

Generic Regional Tower model

• McDonalds• Supermarket

• From RNAV En-route to Feeder Fix• RNAV STAR to Approach.

• Approach will be RNAV (GNSS).• Upgrade to APV (Baro V NAV). • Need to limit choices• Assume VORs (used as approach aid) will go ?• ICAO – PBN APV to all instrument runways by 2016

Chunks – step one

• Queenstown

• By itself – unique – jet – terrain – RNP AR • Current ATM very inefficient with regards to traffic “flow”• Departure example, 23 minute delay once RNP approach

“committed”.• Review in progress.• Next meeting 23, 24, November

Chunks - step two

• RO, HN, TG

• Plan Feb, March, April 2010

• Implement Nov 2010

Chunks – step three

• NV, DN, WP Plan May, June 2010

• NS, WB Plan July, Aug 2010

• OH, PM, NP Plan Sept, October 2010

• NR, GS Plan Feb March 2011

• Implement through 2011

PBN – Issues/Considerations

• Customer needs – sort this out first• Fleet capability • Charting standards• Procedure design capability• Regulator capability (rules) to approve PBN operations• Public vs. Tailored RNP AR• ATM considerations - Mixed mode operations • What noise there is gets concentrated• Who’s going to pay?

PBN – Issues/Considerations (2)

• Equipment performance standards• RAIM Prediction service• Back-up procedures• Contingency – DME/DME, DVOR• Flight planning requirements – ATM• Training requirements

ATM system ability

• A lost message.• ATM system still needs to monitor and assist the aircraft

with PBN • Current ground system could provide much more.• Off track alert - Turn initiation - Cleared altitude vs actual

climb• For ATC to use this ability aircraft need • Enhanced mode s - capable of up grade to• ADS-B

RNAV Arrivals – Noise Concentration
