Localizer preview and capture

With FMS selected as the primary source, the PFD can show a cyan LOC preview before localizer capture. The preview is not active localizer guidance. ^[43]

Set up the ILS

Tune the published frequency, set the front course and fly the cleared intercept. Check the source labels and lateral FMA when the signal is received. ^{[9] [43]}

If LOC does not capture

Check frequency, course, preview source, signal and intercept geometry. Do not continue an unstable approach. ^{[43] [44]}
