OPERATION
POWERING UP THE GNS 530
The GNS 530´s power and COM volume are controlled using the COM power/volume
knob (5) at the top left corner of the unit. Rotating it clockwise will turn unit power on
and increase the COM radio volume. After turning the unit on, a 'welcome page' will be
displayed while the unit performs a self test, followed by a 'land data page'.
The database confirmation page will appear next, which shows the current database
information on the NavData card (with the valid operating dates, cycle number and
database type indicated). The database is updated every 28 days, and must be
current for approved instrument approach operations. Information on database
subscriptions is available inside your GNS 530 package.
To acknowledge the database information, press the ENT-key.
Once the database has been acknowledged, the instrument panel self-test page will
appear. To ensure that the GNS 530 and any connected instruments are working
properly, check for the following indications on your HSI and external annunciators:
• Course deviation - half left /
no flag
• TO/FROM flag - TO
The instrument panel self-test page 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 are entered manually.
