Selecting a menu option from the Utility
Page:
1) Press the small right knob momentarily, to
activate the flashing cursor (Figure 10-15).
2) Turn the large right knob to select the desired
menu option
3) Press the ENT Key to view the selected page
(Figure 10-16).
Figure 10-16 Trip Statistics Page
The following menu options are available:
• Checklists - Provides up to nine different user-
defined checklists containing up to 30 items each.
• Flight Timers - Provides count up/down timers,
plus automatic recording of departure time and
total trip time. Departure and total trip time
recording can be configured to run either any time
GNS 530 power is on, or only when ground speed
exceeds 30 knots.
• Trip Statistics - Provides readouts for trip
odometers, average speed, and maximum speed.
These readouts are resettable (individually or all
at once) by pressing the MENU Key to display the
Trip Statistics Page Menu.
• RAIM Prediction - Predicts if GPS coverage is
available for the current location or at a specified
waypoint at any time and date. Receiver
Autonomous Integrity Monitoring (RAIM)
performs checks to ensure that the GNS 530
will have adequate satellite geometry during
the flight. RAIM availability is near 100% in
Oceanic, Enroute, and Terminal phases of flight.
Because FAA TSO requirements for non-precision
approaches specify significantly better satellite
coverage than other flight phases, RAIM may not
be available when flying some approaches. The
GNS 530 automatically monitors RAIM during
approach operations and warn the pilot if RAIM is
not available. In such cases, use an external LOC
receiver instead for many of the non-precision
and precision approaches stored on the Jeppesen
NavData Card. RAIM prediction helps the pilot
plan for a pending flight to confirm GPS operation
during an approach.
An ‘INTEG’ annunciation at the bottom left corner
of the screen (Figure 10-17) indicates that satellite
coverage is insufficient to pass built-in RAIM tests.
When this occurs, the GPS receiver continues to
provide navigation information, but should not
be used for primary navigation guidance. Use an
alternate navigation source.
