Which component shows both ground-based NAVAID data and FMS derived navigation information?

• A. MCS EHSI
• B. Primary Flight Display
• C. Standby Compass
• D. Radar Scope

Answer: (A)

Navigation displays that integrate multiple navigation data sources present a unified view of where you are relative to both ground-based NAVAIDs and your FMS-guided route. The MCS EHSI is designed to show both kinds of information on one screen, letting you see VOR/DME or localizer data alongside GPS/RNAV guidance and the active route. This combination enhances situational awareness by enabling cross-checks between ground-based signals and the FMS plan. The standby compass provides only heading, the radar scope shows weather/traffic, and the primary flight display focuses on basic flight parameters and does not simultaneously present ground-based NAVAID data with FMS navigation.
