On the speed tape, the green line is located at what percentage above the stick shaker speed?

• A. 20%
• B. 26%
• C. 28%
• D. 30%

Answer: (B)

The green line on the speed tape is a visual guard band above the stall warning threshold. It’s set at a fixed percentage—26%—above the stick shaker speed, which marks when a stall is imminent. This margin gives pilots a consistent buffer across different weights and configurations, helping maintain safe airspeed and providing time to recover if the stall warning triggers. For example, if the stick shaker speed is 160 knots, the green line would be around 202 knots. It’s a proactive cue, not a limit, designed to keep you safely above the stall region.
