Vertical Speed / VSI / Variometer

 

The vertical speed, or rate of climb/descent, is measured by the change in the 'static' environment pressure. This can be done by measuring the airflow in or out of a bottle!

For General Aviation the vertical speed scale is in 100 feet per minute (where European gliders have a meters per second scale).
