While offering similar precision and minimums, ILS is classified as a "precision approach" whereas LPV is an "approach with vertical guidance (APV)," which primarily impacts alternate airport planning ...

Thales recently won an FAA award for up to 300 ILS systems, to be installed between 2007 and 2013. Many will replace older equipment, but at least 100 systems will provide precision approaches at new ...

It's common misconception, but +V advisory glide slope isn't same as LPV glide path.

ILS approaches are ground-based systems providing lateral and vertical guidance (localizer and glideslope), recognized as the gold standard for precision approaches (including Cat II/III) but ...
