Which instrument would you use to determine your altitude change per minute?

• A. Vertical Velocity Indicator
• B. Airspeed Indicator
• C. Altimeter
• D. Attitude Indicator

Answer: (A)

Rate of altitude change, or how fast you’re climbing or descending, is shown by the vertical velocity indicator. This instrument displays vertical speed in feet per minute (positive for climb, negative for descent) and is driven by changes in the aircraft’s static pressure. The altimeter, while it gives your current altitude, does not show how quickly that altitude is changing. The airspeed indicator measures forward speed, and the attitude indicator shows the aircraft’s orientation relative to the horizon. So when you need to know how fast your altitude is changing per minute, the vertical velocity indicator is the direct, read-now source.
