1 System description

While the Cambridge 302 is a good variometer, it needs a graphical display unit if it is to be used as an effective soaring vario and navigation system. The Cambridge solution is to couple a PDA to the 302. However, there are many ergonomic problems with this solution and it is not ideal for mounting in a glider cockpit. Now LX Navigation have solved these problems by using the display of the LX7000 Pro and coupling it with a simple serial cable to the 302. The LX7000 display has all the functionality of a PDA but with improved ergonomics and many added features; all contained in a package that fits a standard 80mm (3") panel cutout.

Logbook and flight statistics available for analysis after the flight
LXe Windows program for basic PC flight analysis, TP manipulation, task preparation and data transfer

3 System Highlights

· Communication between the LX7000 DU and the 302 is based on the published Cambridge proprietary format

· No special settings or modifications required on the 302, and all Cambridge functions, including the IGC approved recorder still operate.

· Data received from the 302:

- GPS position

- TAS

- Vario reading

- Pressure altitude

· Commands sent to the 302:

- MC setting

- Ballast,

- Audio volume (volume on 302 can be changed rotating knob on LX 7000 DU)

- IGC task declaration can be sent from LX 7000 DU directly to 302
