According to the Instrument PTS, you may use a GPS approach down to LPV minimums to substitute a precision approach.

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 Collins]] (e.g.<ref>http://www.rockwellcollins.com/~/media/Files/Unsecure/Marketing%20Bulletins%20Rev1/BRS/MBLPV%20FMS%20Upgrade%20for%20CRJ200CL850%20BRS110403.ashx {{webarchive|url=https://web.archive.org/web/20160304092050/http://www.rockwellcollins.com/~/media/Files/Unsecure/Marketing%20Bulletins%20Rev1/BRS/MBLPV%20FMS%20Upgrade%20for%20CRJ200CL850%20BRS110403.ashx |date=2016-03-04 }}</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>{{cite web|url=https://www.rockwellcollins.com/Data/Products/Integrated_Systems/Flight_Deck/Pro_Line_Fusion.aspx|title=Pro Line Fusion®|publisher=}}</ref> In 2014, Avidyne began equipping general aviation and business aircraft with the IFD540 and IFD440 Navigators incorporating a touch-screen Flight Management System with full LPV capability.<ref>{{cite web|url=http://www.avidyne.com/products/ifd/index.html|title=Avidyne®|publisher=}}</ref>

LPV is designed to provide {{convert|25|ft|m}} lateral and vertical accuracy 95 percent of the time.<ref>{{cite web |url=http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/library/documents/media/waas/2892bC2a.pdf |title=Archived copy |accessdate=2008-02-18 |deadurl=yes |archiveurl=https://web.archive.org/web/20081004122449/http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/library/documents/media/waas/2892bC2a.pdf |archivedate=2008-10-04 |df= }} {{webarchive|url=https://web.archive.org/web/20081004122449/http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/library/documents/media/waas/2892bC2a.pdf |date=2008-10-04 }}</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 September 17, 2015 the Federal Aviation Administration has published 3,567 LPV approaches at 1,739 airports. This is greater than the number of published Category I ILS procedures.<ref>{{cite web|url=http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/approaches/|title=Satellite Navigation - GPS/WAAS Approaches|publisher=}}</ref>
