What visual indicators show the system is in TASR mode?

• A. Heavy green border; 'displaying recorded data' alert; TASR playback control bar
• B. Red flashing border; 'live data feed' alert; TASR stop button
• C. Blue glow; 'playing' label; TASR pause button
• D. Yellow border; 'recording' alert; TASR control wheel

Answer: (A)

This question tests how TASR mode is visually indicated on the operator interface. In TASR mode you’re reviewing previously recorded data, not monitoring live signals, so the UI uses clear playback-oriented cues. The strongest combination is a heavy green border that frames the TASR view, an alert that explicitly says recorded data is being displayed, and a TASR playback control bar that includes playback controls. Together, these cues make it immediately obvious that you’re in replay mode rather than in live operation.

The other visual cues don’t fit TASR playback as precisely. A red flashing border with a live data feed alert signals live operation, not playback. A blue glow with a playing label and a pause button could imply playback, but without the dedicated TASR playback controls and the explicit recorded-data alert, it’s harder to confirm you’re in the intended review mode. A yellow border plus a recording alert describes recording activity, which is the opposite of playback.
