on the NavData and Terrain Data cards. Database
information highlighted in yellow indicates the database
is not within its effective dates. The NavData database is
updated every 28 days and must be current for approved
instrument approach operations. Information on database
subscriptions is available inside the GNS 430 package.

The Instrument Panel Self-test Page (Figure 1-5)
