GPS PREDICT RAIM 1/1(if ARINC 743/743A GPS is configured)

Used to predict future GPS integrity at any required space/time point.

Display the GPS PREDICT RAIM 1/1 page by pressing [INIT REF], <NAV STATUS> and <PREDICT RAIM>.

IDENT [1L]: Any valid waypoint identifier where GPS integrity predictions are required.

NOTE: Defaults to destination airport on initial display of the page.

ETA [2L]: Estimated time of arrival when GPS integrity predictions are required.

NOTE: Defaults to ETA at the MAP waypoint when page first displayed. If no MAP waypoint yet inserted,

defaults to destination airport reference point. On entry of a flight plan route waypoint identifier, defaults

to ETA at entered route waypoint (based on current wind and speed). When on ground, ETA must be

manually entered. When airborne, predictive RAIM ETA is based on system wind.

NAV STATUS [6L]: Returns to the NAV STATUS INDEX 1/1 page.

SAT DESEL [6R]: Access to the GPS SAT DESELECT 1/1 page.

Predicted GPS integrity at entered IDENT/ETA ± 15 minutes: Displays the most restrictive phase of flight

that should be navigable with GPS at the entered position (identifier) and time (ETA) ± 15 minutes by intervals of

5 minutes. Possible GPS integrity status:

• NONE: GPS would not meet en-route navigation requirements.

• ENRT: GPS should meet en-route navigation requirements.

• TERM: GPS should meet terminal and en-route navigation requirements.

• APPR: GPS should meet GPS instrument approach, terminal and en-route navigation requirements.

• ****: Asterisks indicate that the GPS cannot provide a predicted integrity. The most probable reason is that

the GPS almanac needs to be updated. Allow a maximum of 25 minutes for the GPS to

automatically load the most recent satellite constellation almanac.
