During an ILS approach, what instrument displays horizontal deviation from the localizer course?

Explanation:
Horizontal guidance for an ILS is shown by the localizer deviation indicator. This instrument displays left-right deflection from the localizer course, and keeping it centered means you’re on the localizer path. The glideslope indicator, in contrast, shows vertical deviation from the glideslope. The attitude indicator provides pitch and bank information, and the altimeter shows altitude. So for horizontal deviation from the localizer, you use the localizer deviation indicator.
