Refer to Table 2-4 for the data that is
transmitted on these identical buses.
Bit rate = 100 kbits/sec.
The IRU reads the following data from
these three ports:
label 041- set latitude
label 042- set longitude
label 043- set heading
Labels 041 and 042 are read for Nav
initialization. Label 043 is read
to set heading in attitude mode.
The following data is read from these
two ports:
label 203- pressure altitude
label 204- bare-corrected altitude
label 210- true airspeed
label 212- altitude rate
