ILS button #

ILS/LS Off #

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.
