________ (Do/Do not) use the terrain display for navigation.

• A. Do not
• B. Do use
• C. Never use
• D. Use as needed for navigation

Answer: (A)

Terrain awareness is the purpose of the terrain display. It shows surrounding terrain elevations to help you see potential terrain or obstacle threats and support avoidance decisions. It is not a navigation tool and should not be relied on to determine your route, position, or flight plan. The primary navigation relies on established systems (GPS/INS, radar, TACAN/DME, etc.) and the plotted route, while the terrain display is used to assess terrain proximity and maintain safe clearance. Because terrain data can be imperfect or out of date and its scale may not match your current navigation needs, using it as the main means of navigation could lead to unsafe outcomes. Use it to enhance situational awareness and terrain avoidance, not as the primary navigation source.
