Mechanical Variometer, Vane Type, Model: 5 StVLM 5-3 - Logarithmic Scale - Sensitive

  • 57 mm (2 1/4")
  • ±10 knots
  • Logarithmic scale
  • 1.6 second response time

Note: the 0.9 Liter capacity flask (or 2 x 0.45 L flasks) are not easy to fit into many sailplanes - so this is not a popular option.

Application
With its logarithmic scale, the 5 StVL combines the advantages of a precision variometer with those of a standard variometer.  In the precision range from 0 to ±200 ft/min the graduations are equal to 20 ft/min.  From ±200 ft/min to the end of the scale the instrument is a standard variometer.  The needle travels farther in the low lift/sink range than in high lift/sink range - giving you more information when you need it in weak lift.
Note: Since the scale is not linear, this variometer cannot be used with a MacCready ring.
