Which statement correctly describes the RA depiction difference between MFD and PFD?

• A. RA appears as a solid red square on the MFD and a green vertical speed arc on the PFD
• B. RA appears as a blue circle on the MFD and a red cross on the PFD
• C. RA appears as a flashing yellow square on the MFD and no change on the PFD
• D. RA appears as a white dot on the MFD and a blue arc on the PFD

Answer: (A)

When a TCAS Resolution Advisory is issued, the displays cue it differently to balance urgency with actionable guidance. On the MFD the RA is shown as a solid red square, a bold, attention-grabbing symbol that marks the alert within the traffic display. On the PFD, the same advisory is conveyed as a green vertical speed arc, which represents the recommended vertical speed change to resolve the RA and aligns with the flight guidance cues you see during normal vertical navigation. This separation helps you quickly distinguish the nature of the information: the red square on the MFD signals an active, urgent alert related to other aircraft, while the green vertical speed arc on the PFD provides the corrective action in terms of vertical movement. Other symbolic options don’t align with how RA is typically depicted on these displays, making the described combination the best match for how RA is shown across MFD and PFD.
