A LOC or ILS approach is typically used in which conditions, and what is its general purpose on a check ride?

• A. A VOR approach used primarily for navigation.
• B. A radar-based approach requiring no navigation aids.
• C. A visual approach conducted in clear weather.
• D. A localizer or instrument landing system approach; used in instrument conditions or to demonstrate instrument approach procedures during testing.

Answer: (C)

LOC and ILS approaches are instrument procedures that rely on electronic navigation aids (localizer for lateral guidance, and, in the case of ILS, the glideslope for vertical guidance) rather than visual cues. They’re used when flying conditions require maintaining flight primarily by instruments—instrument meteorological conditions—or when you need to demonstrate instrument approach procedures on a check ride. In this setting, the goal is to show you can accurately follow the published approach, manage course alignment, altitude steps, and may complete the landing using the instrument guidance provided, even when the weather or visibility is limited.

Visual approaches, by contrast, are conducted in clear weather with sufficient visibility and cloud clearance, relying on the pilot’s visual references rather than navigational aids. That distinction is why LOC/ILS is the choice for instrument conditions and instrument approach demonstrations on testing, not a visual approach.
