RAIM Prediction
“RAIM” is an acronym for Receiver Autonomous
Integrity Monitoring, a GPS receiver function that performs
a consistency check on all tracked satellites. RAIM ensures
that the available satellite geometry will allow the receiver
to calculate a position within a specified protection limit
(2.0 nautical miles for oceanic and enroute, 1.0 NM for
terminal and 0.3 NM for non-precision approaches).
During oceanic, enroute, and terminal phases of flight,
RAIM is available nearly 100% of the time.
Because of the tighter protection limit on approaches,
there may be times when RAIM is not available. The
G1000 automatically monitors RAIM and warns you with
an alert message when it is not available. If RAIM is not
available when crossing the FAF, the pilot must fly the
missed approach procedure.
The RAIM prediction function also indicates whether
RAIM will be available for a specified date and time. If
RAIM is not predicted to be available for the final approach
course, the approach does not become active, as indicated
by an “Approach is not active” message, and a “RAIM not
available from FAF to MAP” message.
To predict RAIM availability:
1. Select the GPS Status Page.
2. Press the
FMS
knob. Turn the
small and large
FMS
knobs to select the ‘WAYPOINT’ field.
3. Turn the
small FMS
knob to display the
Waypoint Information Page.
4. Turn the
small and large FMS
knobs to enter
the desired waypoint. Press the
ENT
key to
accept.
5. Turn the
small and large FMS
knobs to enter
an arrival time and press the
ENT
key.
6. Turn the
small and large FMS
knob to enter an
arrival date.
7. The cursor highlights the ‘COMPUTE RAIM’
field. Press the
ENT
key to compute RAIM. The
following options are displayed:
• ‘COMPUTE RAIM?’ if RAIM has not been
computed for the current waypoint, time, and
date combination
• ‘COMPUTING AVAILABILITY’ if the RAIM
calculation is in progress
• ‘RAIM AVAILABLE’ if RAIM is predicted to
be available for the given combination of
waypoint, time, and date
• ‘RAIM NOT AVAILABLE’ if RAIM is predicted
to be unavailable for the given combination of
waypoint, time, and date
NOTE
: RAIM computations predict satellite
coverage /- 15 minutes of the specified
arrival date and time.
