What Does VVI Stand For?

VVI stands for Vertical Velocity Indicator

The Vertical Velocity Indicator (VVI) is an essential instrument in aviation that displays the rate of climb or descent of an aircraft. It measures vertical speed in feet per minute (fpm) and assists pilots in maintaining optimal altitude performance during flight. By providing real-time data, the VVI enhances situational awareness, allowing for informed decisions regarding ascent or descent trajectories. This indicator is crucial for safe and efficient flight operations, especially during critical phases such as takeoff and landing.
