Purpose
The position initialization (POS INIT) 1/3 page lets the user enter a reference position for the air data inertial reference unit (ADIRU) alignment. The page also shows the FMCS time reference.
Page Access
To get access to the POS INIT 1/3 page, do one of these steps:
*
Push POS INIT from the INIT/REF 1/3 page
*
Push POS INIT from the IDENT page
*
Push POS INIT from the TAKEOFF REF page

Information
Line 4L shows the UTC time.
Line 1R shows the FMCF last calculated position. If the FMCF position is not valid, the last valid FMCF position shows.
Line 2R shows the reference airport position. This position shows when an airport identification is in line 2L.

Line 3R shows the reference gate position. This position shows with a gate entry in line 3L.
Line 4R shows the global positioning system (GPS) position.
Entries
This page permits entries of airports and gate identifiers in order to get the latitude and longitude from the navigation database. These latitudes and longitudes are available to initialize the ADIRU.
Do this to get the latitude and longitude of an airport:
*
Type a valid airport identifier into the scratchpad
*
Enter into 2L
*
The latitude and longitude of the airport shows in 2R.
Do this to get the latitude and longitude of a gate at an airport:
*
Type a valid gate identifier into the scratchpad
*
Enter into 3L
*
The latitude and longitude of the gate shows in 3R.
To initialize the ADIRU, there are two steps. First, enter a latitude and longitude into the scratchpad with one of these steps:
