ClearNav Parts

Nav Mount


Nav Display Gooseneck Mounts

Kits and components provide 4" (100mm) or 6" (150mm) offset from instrument panel.

The gooseneck can be installed directly on the panel by drilling a 10mm hole ... or by use of an existing 57mm instrument hole using the custom panel mounting plate.

This plate attaches on the back side of the panel and provides a center gooseneck mounting hole - plus an offset corner hole.

The plate can be rotated on installation to put the offset gooseneck mounting hole in any quadrant - allowing optimum placement of the instrument.

The Nav Display attaches to the instrument mounting plate using the corner instrument mounting posts and four new nylon nuts (black) supplied with the kit.

See the price list for available kits and components.


ClearNav Remote Speaker

A remote speaker dramatically improves the clarity and volume of audio alerts (ex. "Target ... eleven o'clock high.") generated by ClearNav Flight Computers that are conected to a FLARM.

This unit is very compact (3.25" x 3.25" x 2.25") and light - allowing any number of creative mounting options in a tight cockpit.

Unit comes with a removable mounting bracket, six feet of connecting wire, and a plug.

See Tech Notes for important connection details.



Variometer Temperature Probe

A remote temperature probe will allow the ClearNav Variometer to calculate more accurate true airspeed which leads to more accurate wind speed and vector calculations.

See the Air Data Computer Connector Map in Tech Notes for important connection details..


Remote Control, Stick Mounted

Retrofitting for the Stick Handle Remote is possible at any time after installing the ClearNav. Retaining the original handheld remote is recommended to enable use in other gliders or at home with the power adapter.

When placing an order please provide the radio brand and the model so we can provide the correct remote control PTT circuit. The PTT electronics differ by radio.

Second Seat Installation

The same mounting options and components are used when installing the ClearNav in the second seat in a duo glider. Two ClearNav systems installed in one glider will operate completely independently as they each contain a GPS and full functionality. If one ClearNav is connected to a Cambridge 302 for airspeed data, a CANbus extension cable may be used to connect the two Nexus Boards to enable sharing of the airspeed data. Additional data and function sharing may be available in the future.
