EFIS Control Panel

To show the TCAS data on the display, put the mode selector on the EFIS control panel in one of these modes:

· Expanded approach

· Expanded VOR

· Expanded map

· Centered map.

The range selector selects the range for the ND.

Push the TFC (traffic) switch on the range selector to let the ND show the TCAS data. When you do this, the TFC message and the TCAS symbols of any targets show on the display.

If the function selector on the ATC control panel is not in the TA or TA/RA position, the display does this:

· Shows an amber message, TCAS OFF (TCAS OFF shows in all ND modes)

· Removes all TCAS target symbols.

To remove the TCAS messages and symbols from the display, push the TFC switch again.

ATC/TCAS Control Panel

The ATC/TCAS control panel sends control data through the ATC Mode S transponder to the TCAS computer. The TCAS computer sends this data to the DEU for display.

The function selector puts the TCAS computer in the TA only or TA/RA mode. In the TA only mode, the TCAS does not supply RA traffic symbols or advisories. It also does not supply RA aural messages. The function selector can also put the TCAS computer in the test mode.

The ND shows the relative altitude of the target above or below the symbol.
