A vertical speed indicator (VSI), often called a rate of climb and descent indicator (RCDI), is a device that shows how quickly an aircraft is climbing or descending.
The vertical speed is calculated by the VSI using the aircraft pitot-static system, and the result is shown on a traditional needle and circular scale instrument or on a ribbon at the side of an EADI electronic flight instrument system.
A barometer capsule is housed in a sealed casing in a basic VSI. The pitot-static system supplies static pressure to the capsule, and the casing is also connected to it via a calibrated nozzle.
There is a delay between a change in static pressure and the pressure that is felt inside the casing because the nozzle inhibits the flow of air.
As a result, as the aircraft ascends (or lowers), the pressure inside the capsule will drop (rise), but it does so more slowly inside the case due to the nozzle’s presence.
A mechanical system translates the movement of the capsule into the movement of a needle.
Global vertical speed indicators market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Vertical Speed Indicator TL-3624 is appropriate for both gliders and aircraft. The Vertical Speed Indicator’s buttons make it simple to set a range of climb/descent, and the device will track it for you and send you audio alerts.
The Vertical Speed Indicator also allows you to review the history of measured values at any moment using a PC and the delivery application.
The Acoustic Vertical Speed Indicator has the following basic features: – when the external button is pressed, the maximum climb and descent rate reached are displayed immediately; – when using your PC, you can download the flight history from the Acoustic Vertical Speed Indicator at any time (the climb/descent rate, including symbols and GPS positioning); – you can always download the most recent firmware to your Acoustic Vertical Speed Indicator, ensuring that you always have the most recent features they prepare for you.
It uses an integration or averaging memory with a customizable averaging period to measure the climb and descent rates with great precision.
Use the acoustic climb and descent rate signals and configure the climb and descent rate limit values at two levels (Warning and Alarm),link the Acoustic Vertical Speed Indicator to the GPS to find the aircraft’s location, and then use the external button to store this location in memory.
