next, which shows the current database information
on the NavData Card 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 GPS 400 package.

and other connected instruments:
• Course deviation - half left/no flag
• TO/FROM flag - TO
• Bearing to destination - 135°

• All external annunciators (if installed) - on
• Glideslope - half up/no flag

The Instrument Panel Self-test Page (Figure 1-6)
indicates the currently selected OBS course, fuel capacity
(CAP), fuel on board (FOB), and fuel flow (FF). The fuel
capacity, fuel on board, and fuel flow may be manually
entered if the installation does not include connection to
sensors which automatically provide these figures.
Entering fuel capacity, fuel on board,
or fuel flow figures (if not provided by
sensors):
1) Turn the large right knob to select the ‘CAP’,
‘FOB’, or ‘FF’ field.
2) Turn the small and large right knobs to enter
the desired figure (Figures 1-6 and 1-7), then
press the ENT Key.
