In aviation, a variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the pilot of the rate of descent or climb. [1]
The RoC in an aircraft is indicated with a vertical speed indicator (VSI) or instantaneous vertical speed indicator (IVSI). The temporal rate of decrease in altitude is referred to as the rate of descent (RoD) or sink rate. A negative rate of climb corresponds to a positive rate of descent: RoD = −RoC.
The variometer, also known as the vertical speed indicator (VSI) or the vertical velocity indicator (VVI), is the pitot–static instrument used to determine whether or not an aircraft is flying in level flight. [5]

The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
VSI may stand for: . Vertical shaft impactor, a type of impact crusher; Vertical speed indicator, an instrument in an aircraft monitoring rate of descent or climb; Very Short Introductions, a series of books published by Oxford University Press
Dementia impacts nearly seven million older adults in the U.S. But the devastating condition often progresses slowly, making it difficult to know if a loved one is struggling early on. However ...
Refusal speed is the maximum speed during takeoff from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration. [19] Incorrectly, or as an abbreviation, some documentation refers to V ref and/or V rot speeds as "V r ."
