Cobham's APE 4190 clock meets the highest performance demands
while providing all expected functionalities. It is an
integral part of an avionics installation, delivering GPS
synchronization accuracy and degraded-flight mode security through
its ARINC 429 output. This 2ATI electronic clock saves space and
weight, and provides excellent readability with its wide viewing
angle, high-contrast transflective LCD, and day/night automatic
dimmable backlight.
In degraded-flight mode, when GPS is not available, the APE 4190
clock is designed to supply accurate time reference for use by the
avionics system. For additional safety, an optional internal
battery will ensure accurate time is kept in the event of external
power loss.
