How can you display the ILS information on the PFD?

• A. Turn the heading knob
• B. Press the LS pushbutton.
• C. Push the ILS button on the ND
• D. It cannot be displayed

Answer: (B)

To display ILS information on the PFD, you press the Localizer pushbutton (LS). Activating this mode overlays the Localizer and Glide Slope cues onto the primary flight display when an ILS approach is active and the NAV source is set to the approach frequency. This gives you the lateral and vertical guidance directly on the PFD. Turning the heading knob only changes the compass or heading view, not the ILS guidance. The ILS control on the ND affects only the Navigation Display, not the PFD, and the ILS information can indeed be shown on the PFD, so the last option isn’t correct.
