ClearNav Variometer System with Digital Display (no mechanical pointer)
The ClearNav variometer has been receiving very positive reviews from glider pilots around the world. It is a state-of-the-art digital variometer.

ClearNav Vario Flight Report
I have received quite a lot of positive feedback from customers using the ClearNav Vario.  Renny Rozzoni from New Mexico was kind to send the following note:

“Outstanding – It is the best vario I have ever flown with (and I’ve been flying gliders for 43 years)!  It took me about 15 minutes getting used to it, and then over the duration of the flight I experimented with it and tried a few different settings, and I have to tell you – it is fantastic.   The Thermal Assist tool is phenomenal and really helped out in some of those rough New Mexico thermals.  In addition, the digital display screen is very easy to read, well laid out, and the key data can be seen at a glance. They have created a truly outstanding product!”

ClearNav has been working hard and has made major improvements to the CNv variometer with LCD display. The latest software version features a new Thermal Assistant as well as new signal processing with noise rejection and "inertial principles" which make it faster while remaining easy-to-use in flight. The vario has been receiving rave reviews from experienced soaring pilots around the world. The built-in GPS provides the GPS position 5 times every second (most varios only receive GPS position once each second) - which helps explain why the Thermal Assistant is so extremely useful. Experienced soaring pilots who never thought they would find a Thermal Assistant useful are fans of the new feature - it really is amazing! You can see the new Thermal Assistant in the image below. In the image, the glider is on the right and circling to the left. The scale on the left side of the screen is the variometer scale. The glider has just gone through some sink at the edge of the thermal. As the glider continues to circle to the left, the cylindrical thermal strength graph rotates to the right (clockwise) while the glider icon remains stationary. The black arrow points to the strongest part of the thermal. The dashed line indicates when the pilot may want to roll to wings level for a second or two. The lead angle of the dashed line is user configurable. The length of the black arrow indicates how much of a centering correction is recommended. Note: The new Thermal Assistant is only available on CNv varios with the LCD display (the version without a mechanical pointer) and XC software upgrade. Customers with the CNv variometer head with mechanical pointer may want to upgrade to the LCD version so they can take advantage of the new Thermal Assistant feature. With the 25% off sale - now is the perfect time to upgrade. New software enhancements to the moving map screen are also in the works for release soon.

This version of the CNv variometer includes the high-resolution LCD display. The vario scale is displayed graphically on the LCD display instead of using a mechanical pointer. It can do everything that the version with mechanical pointer can do - plus it can display a moving map with waypoints, tasks and sectors (no airspace or terrain).

Upgradeable Functionality With a Simple Software Upgrade
One of the design goals was to be able to supply an upgradeable variometer system that can be upgraded easily.  The design team has met that goal, but rather than have hardware upgrades on the shelf at the factory, they have decided to put the full package of sensors and options into every unit.  Users will pay for only the features they want.  For example, a user could start with a basic unit, then, when they want to upgrade and enable some hardware of software function in the future, they simply buy a software upgrade that is tied to their unit's serial number - enabling any features and pre-installed hardware they desire.  The software upgrade is downloaded to a USB Flash Drive and plugged into the variometer.  It's that simple.  There shouldn't be any need to send the unit back to the factory, because all the hardware is pre-installed when the unit is first shipped - regardless of what set of features are enabled.

I am very excited about the ease of upgrade of the new variometer.  You can buy a simple speed-to-fly vario and upgrade it at any time to a powerful unit with built-in task navigation, PDA support, ClearNav MFD support, and an IGC approved flight recorder - with a simple software download and USB Flash Drive.  Cool!

The CNv variometer includes:

  • TE audio vario
    Fast response with digital filters and user-selected time constants
  • Speed-to-Fly
    Audio tones and display provide feedback for best STF
  • Mechanical pointer
    Still the most effective way to display both magnitude and rate of change
  • High resolution, high contrast backlit graphical display
    Long and short averages of climb and netto and many other parameters
  • Get-home navigation ***
    Glideslope and vectors to the home field with wind correction
  • Wind data ***
    Head and tail winds, graphical and numeric wind
  • Suction (TE probe) or electronic (Pitot and Static) options ***
  • Pnematic TE Compensation with TE Probe
  • Electronic TE Compensation ***
  • In-flight adjustment of TE probe ***
    If the TE probe is under compensating it can be easily adjusted
  • Multi-coated low reflection window for maximum visibility
  • Easy update using USB Flash drive
  • 57 MM size
  • Easy to use
    One knob selects screens, the other screen values, graphical UI
  • PC utility
    Polar entry, netto or relative netto behavior, STF deadband etc can all be set using a configurator program. This program can also control which of many screens appear in flight, and the order in which they appear.
  • Upgradeable at any time to CNv Cross Country version
    You can purchase an upgrade that is tied to the serial number of the unit to upgrade it to a CNv Cross Country.

ClearNav Vario Comparison

It consists of 2 components:Package Discount
Customers that buy the CNv Club Vario at the same time as a ClearNav MFD will receive the XC Upgrade (worth $500) for free.

    57 MM (2 ¼”) display size fits any panel.
    T.E. available either from a suction probe or using pitot and static.
  • In-flight fine tuning of T.E. suction compensation.
  • ADC is highly configurable and provides scalable capability from an entry level basic T.E. vario for club use to a fully featured racing vario including Speed-to-Fly, enhanced wind vector calculations, acceleration corrections to T.E., and a secure flight recorder.
  • Display module also highly configurable with in-flight user control of:
    • Time constants (LCD, pointer and audio)
    • Displayed parameters:
      • Netto
      • T.E. (total energy variometer)
      • Relative netto
      • Smart averager
      • bottom-to-now climb
