PREDICTIVE RAIM REQUESTS
CAUTION:
It is not recommended to perform manual predictive RAIM requests when the aircraft is about to enter
the approach phase of flight as the CMA-9000 FMS automatically sends predictive RAIM requests as
well. No manual predictive RAIM request should be done when the aircraft is within DTG=6 nm to the
FAF waypoint.
Display the NAV STATUS INDEX 1/1 page by pressing [INIT REF], <NAV STATUS> (LSK 5R).
Display the GPS PREDICT RAIM 1/1 page by pressing <PREDICT RAIM> (LSK 1L).
The GPS PREDICT RAIM 1/1 page for the destination airport is displayed, with the current estimated time
of arrival (ETA) in the LSK 2L field. The arrival times listed on the right hand side of the display are for the
ETA (at the centre in reverse video), and at intervals of 5 minutes before and after the ETA, up to a
maximum of 15 minutes. After a short delay, the results of the predictive RAIM computation are displayed
for each arrival time. The possible outcomes are:
DISPLAYED
PREDICTED HIL (NOTE 1)
APPR
Less than or equal to 0.3 nm.
TERM
Greater than 0.3 nm but less than or equal to 1.0 nm.
ENRT
(NOTE 2)
Greater than 1.0 nm but less than or equal to 2.0 nm.
NONE
Greater than 2.0 nm.
" **** "
No computed HIL data due to lack of current almanac information, or due to GPS sensor
failure.
1. To determine the predicted HIL for any waypoint, key the waypoint identifier into the scratchpad and move it
to the IDENT field by pressing LSK 1L.
The ETA field is replaced by dashes ("---"), and the right side of the display blanks.
