Variometrum ⏰

The solution is ingenious: Instead of connecting the variometrum to pure static pressure, connect it to a . This probe combines static pressure with a pitot (ram air) pressure in a specific ratio. When you pull back to climb, the ram pressure drops (due to slowing down), which artificially adjusts the static pressure reading to cancel out the climb indication.

Modern electronic varios add —a rising beep frequency for lift, a lowering tone or silence for sink. This allows glider pilots to keep their eyes outside the cockpit, listening to the variometrum like a submarine sonar. variometrum
