What does the upper half of the VSI display?

• A. Rate of climb in 500 ft increments from 1000 ft to 6000 ft
• B. Rate of climb in 50 ft increments
• C. Rate of climb in 200 ft increments
• D. Rate of climb in 100 ft increments from 0 to 1000 ft

Answer: (D)

The VSI’s main job is to show how fast you’re moving up or down. The upper half specifically handles the positive, or climb, side and is laid out in 100 fpm increments from 0 up to 1000 fpm. This gives you a precise, easy-to-read cue for shallow to moderate climbs, letting you quickly judge and adjust your vertical speed to stay on the desired flight path. Other options would imply different step sizes or ranges that don’t match how this portion of the VSI is scaled, making them less useful for the common climb rates you need to monitor.
