GNSS Landing System

32Instrument Landing System (ILS)

First developed in late 1920’s

First flown with passengers in 1938 into Pittsburgh using a Boeing 247-D

33GNSS Landing System (GLS)

A correction to the GPS position is calculated by the Ground Based Augmentation System (GBAS) and transmitted to the airplane via datalink

The accuracy achieved is then generally better than 1 metre

37RNP to GLS

First RNP to GLS operation in revenue service involving 737NG in May 2009

Extremely smooth transitionRadar & ADS-B data confirm track conformance

Fuel saving of 140 kg (168 litres) per flight over conventional radar vectoring to ILS

Emission reduction of 440 kg CO2

Noise reductions

Technology can enable stable accurate paths to increase airspacecapacityand safety

Reduced inter-arrival spacing

Options for sequencing

More efficient routing via paths of specified width

Improved reliabilityin poor weather

We need toembrace changeto make it happen

40Summary

GNSS based technologies improve the safety and efficiency of flying operations

This has been proven during in-service evaluations

A large number of people within Qantas, Boeing, Honeywell, Rockwell-Collins, AirservicesAustralia and CASA have contributed to the success of these projects
