While both offer similar precision, ILS relies on local ground infrastructure prone to localized interference, whereas LPV uses satellite-based WAAS, susceptible to GPS jamming and space weather. ILS ...

The FAA has rapidly introduced WAAS-based GPS instrument approaches (e.g., LPV, LNAV/VNAV) that provide ILS-like vertical guidance and a constant-angle descent, aiming to replace traditional "dive-and ...
