Some problems LPV is helping to resolve
• Schedule reliability for charter or scheduled flights due to absence of traditional ground-based approach aids on remote destinations.
– Issues: Runways without ILS, severe weather, and night landing
• Reduce airport maintenance with planned removal of ILS facilities – Re-confirmed by FAA during LPV progress meeting (Feb 2013)
• Cost of new infrastructure – ILS is costly to install compared to publishing an LPV approach
– Maintenance: periodic LPV re-survey versus ILS antenna re-cal
• NPA are designed with step-down level-off segments: fuel burn
• ILS Weaknesses – Clear surrounding area (multipath issues)
– Must be “on the runway”
– ILS ground support equipment failures
– Occasional glide-slope “glitches” causing go-arounds
• FAA current plan is to no longer establish new Category- I ILS – Ref.: CNS Task Force meeting August 17,2011

Operation
According to Chris Drossos, 737-300 project pilot for
Canadian North
"The addition of LPV capability to our aircraft permits
us to provide significantly improved schedule
reliability for our scheduled and charter clients,
given the absence of traditional ground-based
approach aids at many of the remote Canadian
destinations we serve. From the pilot's perspective,
CMC's LPV system provides a clean, straightforward
interface which behaves exactly like an ILS, but with
the exceptional WAAS performance and availability."

• LPV approaches/vertical guidance derived exclusively
from SBAS and are not affected by temperature.
• Design criteria is very much like an ILS and can be as
low as 200 with a half mile visibility.
• AC 90-107 provides guidance for operational approval
• OpSpec/MSpec/LOA paragraph C052 and C053 provide
guidance on training requirements

– Select a RNAV Approach plate for Runway (example RNAV 13R) for the LPV approach
– New Action: Enter the 5 digit number into the Control Panel, the 5 digit number is obtained from the approach plate’s WAAS Channel Number, eg 80090.
– New Action: Select LPV approach using source select switch on forward instrument panel.
– Maintain map mode on ND during approach
– Select LAND/ILS mode on autopilot
– Autopilot transitions to ILS/LPV as per normal
– FMS indicates normal precision approach
– Pilot flies LPV like a standard Cat I ILS approach procedure
• Missed approach as per ILS

Localizer performance with vertical guidance (LPV)
• Operational Benefits
– LPV is ILS Look-Alike
– LPV plates are RNAV procedures
– LPV is here and is expanding globally.
– Implementation brings immediate savings
– Installation in all aircraft is a reasonable and achievable bolt-on task
– The CMA-5024 is certified, airline proven-in-service, with LPV
– Reduced dependence on terrestrial navaids
• Improved dispatch reliability SIDS (use SBAS as navigation source)
• Improved STARS (use SBAS as navigation source & LPV)
• Can continue LPV operations when ILS is out-of-service to all runways
– Enhanced operational safety due to the vertical guidance provided
– No operational limitation due to cold weather
– Integrated solution exists with CMA-9000 FMS

Localizer performance with vertical guidance
(LPV) (Cont.) • Infrastructure benefit
– Terrain variation does not impact publication of a LPV approach
– No maintenance (contrast this to ILS continual flight inspection)
– All SBAS services are interoperable (WAAS, EGNOS etc.) so
only one type of SBAS receiver is required
• FAA – LPV published advantages: (source: Federal
Aviation Administration Implementation of WAAS LPV
Procedures) – published in 2004
– Procedure Integrity
– Lower Minimums
– Significantly increases the number of available instrument
approaches

Prepared for the Future… GBAS
• GBAS/GLS is very similar to SBAS/LPV operationally,
both deliver CAT-I performance.
• GBAS is expected to deliver CAT-I to CAT-III operations; however,
certification to CAT-II/III does not exist at this time, and GBAS CAT-I not
deployed yet.
• Differences between the systems
– LPV receives error corrections from SBAS geostationary satellites,
GLS receives error corrections via uplink from GBAS ground station.
– LPV Final Approach Segment (FAS) is hosted in the avionics database,
GLS FAS uplinked via VHF Data Link from the GBAS ground station.
– Concepts between GBAS/GLS and SBAS/LPV are highly similar except
GBAS GLS requires ground stations to work, SBAS LPV is self-contained
• CMA-5025 will provide GBAS capability when infrastructure will be
available
