Line 9:

Examples of receivers providing LPV capability include (from [[Garmin]]) the GTN 7xx & 6xx, GNS 480, GNS 430W & 530W, and the post 2007 [[Garmin G1000]] with GIA 63W.

Various FMS models, GNSS receivers and FMS upgrades are available from [[Rockwell_CollinsRockwell Collins]] (e.g.<ref>http://www.rockwellcollins.com/~/media/Files/Unsecure/Marketing%20Bulletins%20Rev1/BRS/MBLPV%20FMS%20Upgrade%20for%20CRJ200CL850%20BRS110403.ashx</ref>). Most new aircraft and helicopters equipped with integrated flight decks such as Rockwell Collins ProLine (TM) 21 and ProLine Fusion (TM) are LPV-capable. <ref>https://www.rockwellcollins.com/Data/Products/Integrated_Systems/Flight_Deck/Pro_Line_Fusion.aspx</ref>

LPV is designed to provide {{convert|25|ft|m}} lateral and vertical accuracy 95 percent of the time .<ref>http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/library/documents/media/waas/2892bC2a.pdf</ref>. Actual performance has exceeded these levels. WAAS has never been observed to have a vertical error greater than 12 metres in its operational history.{{Citation needed|date=June 2013}}

As of April 2, 2015 the Federal Aviation Administration has published 3,534 LPV approaches at 1,725 airports. This is greater than the number of published Category I ILS procedures.<ref>http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/approaches/</ref>
