The N1 flex thrust indicator on the gauges appears as which of the following?

• A. Magenta caret and a digital "flex"
• B. Red warning banner
• C. Blue digital readout
• D. Green band with white text

Answer: (A)

The display uses a magenta caret accompanied by a digital “flex” to show this mode. When flex thrust is selected for a takeoff, the N1 target is marked on the gauge with that magenta caret, and the word “flex” appears in digital form to remind you that the takeoff thrust is being limited by a flex setting rather than commanded full thrust. This combination is designed to stand out clearly so pilots can instantly recognize that the engine output is governed by the flex value.

The other options don’t fit because a red warning banner would indicate an abnormal condition, not a normal mode indication; a blue digital readout isn’t the standard way flex is shown; and a green band with white text typically signals a safe or normal range, not a mode label like flex.
