SBAS General Facts • SBAS provides the accuracy, integrity, continuity and availability
needed to rely on GNSS navigation for all phases of flight, from en-route through to category 1 approach.
• SBAS technology provides the opportunity to cover very large areas of airspace not served by other navigation aids
• SBAS adds increased capability, flexibility and generally more cost-effective navigation options than legacy ground-based navigation aids.
• SBAS is available in most non-aviation uses of GNSS applications. It should be an essential component of our National infrastructure.

SBAS Benefits En-route
• SBAS is considered a primary navigation system
• SBAS allows for RAIM and FDE
• ADSB requires the use of an SBAS capable receiver
• Accuracy, Reliability, Integrity.

SBAS benefits in the Approach • Provides Cat 1 equivalent vertical guidance at any qualifying runway
• Localiser Performance with Vertical Guidance (LPV) meets ICAO standards required in resolution 37-11
• From a pilot’s viewpoint, an LPV approach looks and flies like an ILS
• SBAS service does not require the installation or maintenance of ground-based landing system navigation aids
• SBAS is immune to barometric and temperature fluctuations or improper settings of QNH
• SBAS provides positive guidance RNP 0.3 across service area.

SBAS LPV equipped aircraft estimated by FAA
• Total estimated SBAS equipped aircraft by FAA in August 2014 was
74,572
• This includes not just GA but all sizes and makes up to the A350 Airbus and includes Helicopters.

Airbus A350 XWB Airbus new acronym “The xLS function”
• The new SBAS/LPV approaches are halfway between RNAV and GLS approaches (GLS = Cat 3)
• Technology is similar to GLS
• RNAV / LPV approaches fit perfectly in the Airbus xLS concept
• SLS is the acronym selected by Airbus for the A/C function supporting SBAS applications it pops up on the screen to identify the approach
• Airbus SLS function is first introduced on the A350 XWB.

SLS / LPV Standard Operating Procedure
• LPV approaches with the SLS function are flown like an ILS approach.
• LPV approaches are published as RNAV(GNSS) with LPV Minima
• Approach Preparation is the same as usual
• Approach Execution is the same as usual

Airbus Test Pilot Feedback • Geometric Glide Path is a real asset compared to BaroVNAV
• SLS /LPV signal observed on the A350 is operationally equivalent to Cat 1 ILS and sometimes better
• A/C position relative to FAS is always available and reliable
• No false LOC or GS side lobes.
• Can be made available at almost any runway end without ground infrastructure.
• LPV is the ideal backup solution on main runways currently equipped with ILS (e.g. in case of failure or maintenance)

From the Airbus Test pilot
“As an operational Pilot this is what I would like to see”
• LPV approaches at all runways with adequate SBAS coverage.
• Additional SBAS constellations / regions.
• LPV 200 capability and real Cat 1 minima.
• LPV solution on more aircraft types.

AU / NZ SBAS will happen
• It should be a National infrastructure project, not just Aviation.
• The safety benefits are greater for Aviation BUT USED BY ALL
• Maritime = accurate positioning
• Rail = ticketing & control
• Road = road user charges, alerts
• General = tourism, SAR functions, PLB’s
• Precision Agriculture

Where are we now...
• Next important meeting is March 24th 25th 2015 in Canberra
• Involves highest level of Government agencies from both countries
• Promoted by Thales Alenia Space with emphasis on an EGNOS duplication
• Supported by AOPA Australia and AOPA NZ
• New Zealand & Australian Regional and GA operators need to get behind this initiative.

SBAS Basics
• The FMS database has a data block with lateral and vertical definition.
• Data block transmitted from FMS to Sensor Unit (GNSSU), used to compute lateral & vertical deviations
• LPV - Localiser Performance with Vertical Guidance

SBAS vs ILS
• LPV – similar terminology to ILS.
• Essentially designed in the same way as an ILS except for the Vertical Alarm Limit
• ILS Cat I – 12m
• SBAS APV 1 – 50m
• More design options for ILS e.g. Collision Risk Modelling
