IVSI – Instantaneous Vertical Speed Indicator
IVSI stands for Instantaneous Vertical Speed Indicator. This instrument is used in aviation to measure the rate of change of the aircraft’s altitude. It works by comparing the difference in pressure between two ports on the instrument, one of which is connected to a static source and the other to the aircraft’s pitot system.
The IVSI provides real-time information on the aircraft’s vertical speed and can be used by pilots to maintain a desired rate of climb or descent. It is an important tool for ensuring safe and efficient flight, particularly during takeoff and landing.
Overall, the IVSI plays a crucial role in modern aviation, providing pilots with the information they need to make informed decisions and navigate their aircraft with precision and accuracy.
