The ILS/LS Button when pushed cycles the localizer and glideslope scales ON or OFF. It also displays:

  • The ILS identifier & frequency
  • ILS DME on the associated PFD if a DME is collocated
  • The ILS course bar on the heading scale
  • Deviation symbols are displayed when a valid ILS signal is received

The LS label may replace the ILS label on some aircraft. The ILS/LS Button illuminates green when selected ON.
