CLOCKS -GENERAL DESCRIPTION
General
This is the data that the clocks show:
*
Time and date set manually from the clock
*
Universal time (controlled) (UTC) and date from the airplane information management system (AIMS)
*
Elapsed time
*
Chronograph time.
Use the clock switches on the glareshield panel to control the chronograph function of the clocks.
The clocks send manually set time and date to the airplane information management system (AIMS) cabinets. However, the AIMS cabinets do not use the clock time and date for any function.
The AIMS cabinets get UTC and date from the the multi-mode receivers (MMRs).

CLOCKS -INTERFACES
Power
Each clock gets 28v dc from a circuit breaker for operation. Each clock gets 5v ac for its internal instrument lights.
Clock Switches
Each clock gets a discrete signal from a clock switch on the glareshield. These discrete signals control the chronograph function of the clock.
Digital Input
The left clock receives universal time (coordinated) (UTC) and date from the left AIMS cabinet. The right clock receives UTC and date from the right AIMS cabinet.
