When it comes to precision, Astrotech's LC-6 five-function quartz chronometer is up to the task. It is specifically designed to meet the increased demands of IFR and VFR flight. It is panel mounted, aircraft powered, and contains an internal keep-alive battery with 14 and 28-volt lamps.

The LC-6 has a customized large scale integrated circuit (LSI) chip which consists of several hundred transistors. The LSI chip is attached to a single circuit board, a simplified construction resulting in superior reliability and performance. In addition, this circuitry is not subject to dirt, vibration, friction, or the wear inherent in mechanical clock movements. For more information, see the features and specifications below.
