The CNv continues the ClearNav design philosophy of providing robust and configurable products which are simple to use and require a minimum of heads-down time in the cockpit.

While every CNv ships with a complete package of hardware and software, upgrades are enabled via downloadable software modules, allowing pilots to select the exact performance package appropriate to their needs.

The new Nav Display Climb screen is displayed in the photo on the left. A view of all screens can be seen in the user manual.

The CNv is offered in two performance packages:

  • CNv Club Vario:   High performance speed-to-fly variometer with wind display and Get Home navigation feature.
  • Cross Country (XC) License Pack:   Add secure flight recorder and task declaration displays. Provides navigation displays and task editing and serial data out to drive third-party navigation.
