Beep Trim does what?

• A. Modifies the attitude reference in ATT MODE and adjusts corresponding upper-mode references when engaged.
• B. Engages the autopilot
• C. Resets the go-around state
• D. Changes the aircraft color display

Answer: (A)

Beep Trim changes the target attitude that the attitude-hold mode uses. When it’s engaged, the system shifts the attitude reference that ATT MODE is trying to maintain, and it also updates any higher-level references that depend on that attitude. This keeps all parts of the flight-control system aligned with the new trim setting, so the aircraft holds its trimmed attitude with less manual input. Engagement isn’t about turning the autopilot on, resetting a go-around state, or changing display colors—the trim function specifically adjusts the attitude reference and the related upper-mode references so the flight path stays consistent with the new trim.
