What does a red chevron indicate during an aircraft upset?

The presence of a red chevron during an aircraft upset is an important visual cue for pilots. It typically indicates that the aircraft is not in a safe flight attitude and that the control inputs should be adjusted to transition to level flight. When a red chevron appears, it signals to the flight crew that corrective actions are necessary to regain a stable flight path.

While the chevron serves as a clear indication that the aircraft has deviated from the desired flight level, it serves primarily to inform pilots that they need to take action to align the aircraft back to level flight. Understanding the role of visual indicators, such as the red chevron, is crucial for pilots to respond appropriately during critical flight situations.
