SYNCHRONIZATION (MULTI SCREW)
This ClearCommand System utilizes dual lever synchronization. The
advantage of this is that the Control Head levers are active at all times,
which eliminates the possibility of shifting when the engine RPM’s are
not at Idle.
The Control Head levers are in the synchronization range when the
Processors are commanding:
• At least 10 percent of the throttle range
• Commanded throttles are within 10 percent of equal RPM
The Processor’s throttle signals are compared and then matched. The
Processors then send the same signal to both engines. The engines are
now synchronized.
A green indicator light located on the Control Head of the Station-in-
Command indicates engine synchronization:
• When the green light is NOT LIT, no synchronization.
• When the green light is LIT, synchronization.
When in the Synchronization Mode:
• Both Control Head levers have full command of throttle
• Synchronization can be disabled while in the synchronization
range by depressing for one-second the transfer switch of the
Control Head at the Station-in-Command.
• Synchronization can be re-enabled by matching the Control
Head levers and then depressing the transfer switch for one-
second again.
