A fully independent clock is on the right side of the control panel.
It sends time to the centralized fault data interface unit, the flight data interface unit, and
the flight management and guidance computer.
The clock has two electrical supplies, one of which is a direct connection to the aircraft
battery hot bus.
The clock performs four functions :
- It displays "UTC" (GMT) time in hours, minutes and seconds on the center counter.
- It displays elapsed time (ET) (from engine startup) in hours and minutes on the lower
counter.
- It drives the chronometer (CHR), which measures a time interval (from the pushing of
the CHRONO button) in minutes and seconds.
- It can replace the UTC with the date.
