According to the rule of thumb, how should you apply bar width on the attitude indicator for altitude corrections?

• A. For corrections less than 100 ft, full bar width; for greater than 100 ft, half bar width
• B. For corrections less than 100 ft, half bar width; for greater than 100 ft, full bar width
• C. For corrections less than 50 ft, quarter bar width; for greater than 200 ft, full bar width
• D. For corrections less than 120 ft, half bar width; for greater than 120 ft, full bar width

Answer: (B)

The bar width on the attitude indicator is a visual cue for how big the altitude correction is. The idea is to scale the cue with the amount of correction you need to make so you can judge quickly how aggressively to adjust. For a small correction (less than 100 ft), using half the bar width keeps the cue subtle, helping you avoid overreacting to minor error. When the correction is larger (more than 100 ft), using the full bar width makes the cue prominent, signaling that a more noticeable adjustment is warranted. This threshold provides a practical, easy-to-read distinction between minor and significant errors, supporting smoother, more controlled corrections rather than abrupt changes.
