ClearNavToday’s cross-country soaring pilot must gather, display and assimilate a large amount of information. In most glider cockpits, this is still being accomplished with a collection of equipment including a GPS receiver, flight recorder and PDA (Personal Digital Assistant).

Real-world experience with this approach reveals severe limitations: PDA’s weren't designed for aircraft use and are too small and dim to effectively supply information to a busy pilot in a sunlit cockpit. Cabling and connectors tend not to be rugged, so failures are all too common. Flight recorders require tedious and slow file downloads.



The Clear Navigator is the next generation of soaring instrumentation, the only system purpose-built for the task: an integrated hardware and software system that overcomes the shortcomings found in PDA approaches and all other small-display designs.

The ClearNav Instruments vario system has been designed to provide glider pilots with the best possible climb and speed-to-fly guidance, as well as valuable secondary information, including wind speed and direction, air and ground speeds, and altitudes.

The vario can use either probe or purely electronic Total Energy compensation. It fits into a single 57 MM hole and the “black box” (Air Data Computer or “ADC”) can mount either directly to the display module or separately for maximum flexibility.

The vario has been designed to be fully compatible with the “ClearNav” display and, through the use of a serial data port, can also integrate with other moving map/glideslope devices
