Which port is utilized for the vertical speed indicator (VSI)?

• A. Pressure port
• B. Static port
• C. Dynamic port
• D. Altitude port

Answer: (B)

The vertical speed indicator (VSI) measures the rate of climb or descent of the aircraft, providing essential information for pilots about the aircraft's vertical performance. The VSI operates based on changes in air pressure. The correct choice, the static port, is where the VSI measures ambient atmospheric pressure. As the aircraft ascends or descends, the static pressure changes, which the VSI interprets to give a reading of the vertical speed in feet per minute (fpm). This is crucial for pilots as it helps in maintaining altitude or understanding the aircraft's climb rate during takeoff or approach. In contrast, other ports such as the dynamic port are more related to measuring airspeed and not suited for the function of the VSI. Thus, the static port is vital for accurately assessing vertical movement, making it the correct choice for this question.
