Picture
Whether flying contests, OLC flights, badge flights or just plain flying for fun, the ClearNav II Flight Computer gives you everything you need to fly.
  • Task management
  • Airspace
  • Landability information
All clearly presented on the large, high contrast and extremely bright LCD display.

Essential flight data is clearly and logically presented on the bottom of the screen and is highly configurable.  A simple and intuitive user interface make for a fast learning experience and does not require a manual or even a quick-start card if you don’t fly for a couple of weeks.




Our design philosophy is focused on ease of use, and on providing the pilot with information just from glancing at the screen.  An example of this is the landability amoeba which shows the glide range in all directions taking into account the glider polar, MC setting, wind, height, and terrain.  Another example is our unique presentation of equidistant arcs which greatly simplifies area task management.
The combination of a nine-button controller and a “block” cursor minimizes heads down time and makes for fast and easy screen selections. Finally, flexible mounting options allow for installation in almost any glider.

Quick Reference Card
Simple Navigation
A single button-touch summons a simple “ribbon” menu with large clear icons that control all frequently used functions and values.
Picture
Considerable care has been taken to ensure the user interface is simple and consistent — buttons do what a pilot expects them to do. This contributes to the goal of a straightforward instrument that serves, rather than fights, the pilot. ​

​Moving map with selectable layers
Moving map shows just the right degree of contour and terrain information, together with clear display of airports and turnpoints. User settings allow you to show or suppress selected details as desired.
​Glide “amoeba”
ClearNavigator’s unique visual presentation of all areas you can reach given current conditions. This instantly understandable graphical presentation of your landable footprint takes altitude, glider polar, wind and terrain into account and also depicts your reachable footprint above a user-settable arrival altitude
Task optimization
Includes intuitive area task optimization through clearly drawn turn point arcs.
Airspace monitor
Visual display of all SUA’s, with audio proximity alarms and easily accessed details.
Flarm Alert
Visual and Audio alerts of all FLARM and transponder traffic.
Integral GPS & Secure Flight Recorder
The ClearNav includes a state-of-the-art rapid-update (4 Hz) GPS engine for accurate position sensing, and a secure IGC Certified flight recorder that makes a complete record of every flight.

Airspeed Input Compatibility
The ClearNav’s high resolution GPS and software allow it to accurately calculate wind from thermal displacement. However, the ClearNav can also accept airspeed data input from the ClearNav Vario for even more accurate wind calculations in all circumstances.  The CNII may also be connected to the Cambridge 302.

Near Unlimited Memory & Easy Data Transfer
The ClearNav has a 2GB internal flash memory capable of holding turn point, terrain, map, and airspace information for a substantial part of the earth’s surface. The ClearNav will be able to hold detailed data for all the sites that a typical pilot might fly in a lifetime, as well as flight logs covering hundreds of flying hours. Pilots will appreciate never again having to struggle with the constraints of limited memory.

Picture
​The ClearNav ships standard with a small handheld remote designed to be easily operated with the non-flying hand. At the heart of the ClearNav 9-button configuration is the standard “up-down-left-right-select” combination commonly found on AV and game remotes, phones, cameras and more. The function of these controls is familiar and instantly clear to every user. The buttons have a logical layout and excellent feedback. Pilots quickly find that they never need to look at the remote to operate the ClearNav. As an optional accessory, we offer an elegant teak stick handle with the remote keypad (plus PTT button) incorporated in the ergonomically designed top.
The ClearNav display is not cluttered with confusing buttons or dials. There are no rows of unmarked buttons, or even worse, buttons whose functions change unpredictably on different screens, thus competing for the pilot’s attention during flight. The ClearNav also does not employ a touch screen. They are difficult to reach in some gliders and are extremely challenging to operate in turbulence. We believe the combination of the keypad and the “block” cursor is the optimal control solution in a glider.
