Line 1R shows the CROSSWIND data field. This shows the
current crosswind component direction and speed.
Line 2R shows the SAT/ISA DEV data field. This shows the
current static air temperature (SAT) and the equivalent
international standard atmosphere (ISA) deviation. The SAT
indication is blank on the ground.
Line 3R shows the VERT DEV data field. This shows the present
vertical deviation from the calculated vertical guidance path
during descent. In climb and cruise, this data field is blank.
Line 4R shows the TAS data field. This shows the current true
airspeed.
Line 5R shows the PROGRESS REPORT prompt. This lets the
flight crew downlink a flight progress report with an ACARS

Nav Status Page
This page shows the status of the navaids tuned or in use by the
FMCS.
Line 1L and 1R show the VOR/ILS data fields. This shows the
VOR or ILS identifiers and frequencies that are currently tuned

tuned by the FMCS through the DME interrogators.
The status of each tuned DME identifier/frequency shows this
information:
* If the navaid input is used in the navigation calculation, the
navaid identifier and frequency are in large font and the
identifier has a highlight
* If the navaid input is received but is not used in the
navigation calculation, the identifier and frequency are in
large font and there is no highlight
* If the frequency is tuned but valid data is not received, the
identifier and frequency are in small font and there is no
highlight
* If no frequency is received or the frequency sign status
matrix (SSM) is fail, FAIL shows in small font.
* If there is no identifier for a frequency shown, the identifier
field is blank
* If the navaid frequency SSM is no computed data (NCD), the
identifier and frequency are blank.
Lines 5L and 5R show the currently selected GPS and IRS used
in the FMCS navigation sub-function calculations. The GPS
display is blank if the GPS is inhibited for use in the navigation
sub-function.
