previous item.
The following items are available:
Checklists — provides up to nine different user-de-
fined 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 500W-series unit
power is on, or only when your ground speed exceeds
30 knots.
Trip Statistics — provides readouts for trip odom-
eters, average speed and maximum speed. These
readouts are resettable (individually or all at once) by
pressing MENU to display an options window.
RAIM Prediction — predicts if GPS coverage is
available for your current location or at a specified
waypoint at any time and date. Receiver Autonomous
Integrity Monitoring performs checks to ensure that
the 500W-series unit has adequate satellite geometry
during your flight. RAIM availability is near 100%
in Oceanic, En Route and Terminal phases of flight.
Because the FAA' s TSO requirements for non-precision
approaches specify significantly better satellite cover-
age than other flight phases, RAIM may not be avail-
able when flying some approaches. The 500W-series
unit automatically monitors RAIM during approach
operations and warns you if RAIM is not available.
In such cases, use the GNS 530W' s VLOC receiver
instead for the approaches. RAIM prediction helps you
plan for a pending flight to confirm GPS operation
during an approach.
RAIM prediction only predicts the availability of
Fault Detection (FD) integrity in the absence of WAAS
corrections. It cannot predict the availability of LPV
or L/VNAV approaches. The FAA provides a NOTAM
service for LPV approach availability.
An "INTEG" annunciation at the bottom left corner of the
screen indicates that satellite coverage is insufficient to pass
built-in receiver autonomous integrity monitoring (RAIM)
tests. When this occurs, the GPS receiver continues to provide
navigation information, but should not be used for primary
navigation guidance. Use the GNS 530W's VLOC receiver or
another suitable navigation source.
