A Vertical Speed Indicator (VSI), also known as a Rate of Climb and Descent Indicator (RCDI) is an instrument which indicates the rate of climb or descent of an aircraft. The VSI uses the aircraft pitot-static system to determine the vertical speed and depicts the result on a conventional needle and circular scale instrument, or on a ribbon at ...

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. It can be calibrated in metres per second, feet per minute (1 ft/min = 0.00508 m/s) or knots (1 kn ≈ ...

The Vertical Speed Indicator (VSI) is an instrument that displays rate of climb and descent to the pilot by measuring rate-of-pressure changes. This information helps the pilot determine the aircraft's trend. Reacts before changes in the altimeter is sensed allowing the pilot to be alerted quicker. May be referred to as a Rate-of-Climb ...

The VSI, or variable source inverter, was the earliest solid state VFD. It is sometimes called a "six-step" drive because of the voltage sent to the motor. Variable source inverter operation is relatively simple. Basically, AC input voltage and frequency is converted to DC by rectifiers, then converted back to AC through the inverter section ...

VSI is mainly used to convert a constant DC voltage into an AC voltage with variable magnitude and frequency. Fig. 3.6 shows a schematic diagram of a three-phase VSI. The inverter is composed of six switches S inv,1 through S inv,6 with each phase output connected to the middle of each inverter leg. In the simplest form, three reference signals are compared to a high-frequency carrier waveform ...

Operation of 120° Mode Inverter: The firing sequence for 120° Mode Inverter Operation is tabulated below. It can be seen from the above table that each of the thyristor conducts for 120° duration only and it remains off for the next 60°. This is different from 180° operation mode where each thyristor conducts for 180° duration.

Vertical Speed Indicator (VSI) is an instrument that uses static pressure to display a rate of climb or descent in feet per minute. The VSI can also sometimes be called a vertical velocity indicator (VVI). The vertical speed indicator (VSI), which is sometimes called a vertical velocity indicator (VVI), indicates whether the airplane is climbing, descending, or in level flight.
