Where is the VMC speed indicated on the airspeed indicator?

• A. Green arc.
• B. White arc.
• C. Yellow arc.
• D. Red radial line.

Answer: (D)

The concept being tested is the minimum controllable speed with an engine inoperative. VMC is a critical speed you must not go below when one engine is not producing thrust, because flying slower can reduce rudder effectiveness and lead to loss of directional control. On the airspeed indicator, this speed is shown as a red radial line. This marker provides a quick, visual cue to stay above a specific speed in engine-out conditions. The colored arcs (green for normal operating range, white for full-flap operating range, yellow for caution) indicate different operating envelopes, but they do not designate VMC. Since VMC changes with weight, altitude, and configuration, the red line serves as a constant reference on the instrument, while the exact VMC value is determined from performance data for the current conditions.
