Instantaneous Vertical Speed Indicator (IVSI)
The Instantaneous Vertical Speed Indicator (IVSI) is an aircraft instrument that provides pilots with real-time information about the aircraft’s rate of climb or descent. It functions by instantly indicating the movement of the aircraft in the vertical axis, as displayed on the vertical speed indicator (VSI), with little or no lag time. The IVSI is a valuable tool for pilots, allowing them to make adjustments to their aircraft’s altitude in real-time, ensuring a smoother flight experience. The IVSI is a crucial component in identifying any unexpected changes in vertical speed, which can help pilots detect and address potential safety concerns. The IVSI is a simple yet highly effective technology that has become an integral part of aircraft instrumentation over the years, serving as a critical aid for pilots who rely on precise and accurate readings for a safe and successful flight.
