Airbus xLS concept

Approaching runways

November 2017 EIWAC - Airbus xLS concept

Straight approach

• ILS look-alike functions: xLS concept

Curved approach

• RNP AR function

Introduction

• ILS is the reference for straight approaches

• Airbus xLS concept provides ILS look-alike

crew interface

• Airbus xLS concept includes:

• ILS (Instrument Landing System)

• GLS (GBAS Landing System)

• SLS (SBAS Landing System)

• FLS (FMS Landing System): xLS solution for

Non-Precision Approaches with Baro-VNAV

guidance

November 2017 EIWAC - Airbus xLS concept

xLS expands the ILS operational benefits to

all types of approaches

FMS Landing System

• Guidance mode to fly RNAV(GNSS) & conventional approaches

• Aircraft is guided along a virtual beam computed by the FMS

• No ground infrastructure (based on FMS NDB)

• Vertical profile corrected from temperature
