To display TCAS information on the MFD, which control must be pressed?

• A. Turn on the TCAS display switch on the MFD power panel.
• B. Press the TFC button on the Display Control Panel.
• C. Select TCAS from the PFD reversionary panel.
• D. Use the EICAS control panel to enable TCAS.

Answer: (B)

Showing TCAS information on the MFD is controlled from the Display Control Panel, and the TFC button is the control that activates or toggles the TCAS display on the MFD. Pressing TFC brings traffic data into view, so you can see nearby aircraft on the MFD.

Other options don’t fit because:

• Turning on a separate TCAS switch on the MFD power panel would power the display unit but doesn’t enable the TCAS data on it.

• Selecting TCAS from the PFD reversionary panel affects the PFD, not the MFD display.

• The EICAS panel handles engine and systems alerts, not TCAS traffic display.
