Digital Radio Altitude
The Figure 1010 shows an example of a Digital Radio Altitude screen. Line 2
shows the correct radio altitude from the No. 1 digital data source. The plus
(+) sign in position 16 of line 2 shows that Altitude No. 1 source is the active
input. If the Altitude No. 1 data was incorrect, then INVALID would be shown
on line two. Line 3 shows the Altitude No. 2 data in the same procedure that
line 2 shows the Altitude No. 1 data.

line 2 shows the Altitude No. 1 data.

Analog Radio Altitude
The Figure 1011 shows an example of an Analog Radio Altitude screen. Line
2 shows that analog radio altitude No. 1 data is incorrect. If the analog altitude
No. 1 data were correct, then the altitude would be shown on line 2. A plus
sign (+) in position 16 of line 3 shows that altitude source is the active input.
Line 3 shows the correct altitude from analog altitude No. 2 and the plus sign
shows that analog radio altitude No. 2 is the active altitude source.
2 shows that analog radio altitude No. 1 data is incorrect. If the analog altitude
No. 1 data were correct, then the altitude would be shown on line 2. A plus
sign (+) in position 16 of line 3 shows that altitude source is the active input.
Line 3 shows the correct altitude from analog altitude No. 2 and the plus sign
shows that analog radio altitude No. 2 is the active altitude source.

Pressure Altitude
The pressure altitude data is supplied to TCAS from the transponder through
XT Coordination No. 1 and No. 2 ARINC 429 data bus (Data Word Label 203).
Figure 1012 shows a sample Pressure Altitude screen. Line 2 contains the
altitude data from XT Coordination No. 1 pressure altitude data source. In this
example the data source is correct (altitude = 2400 ft.) and the plus sign
shows that the XPDR No. 1 is the active source. If the data is correct, then
line 2 shows INVALID. The line 3 indications are almost the same except that
they are for XPDR No. 2.
