alignment of rudderstock/Steering Gear, radial forces from rudder and the operation profile of the
Steering Gear.
Steering Gear Performance Monitoring System (SG PMS):
The purpose of the performance monitoring system is to continuously monitor, process and record
performance and operation parameters of the Steering Gear and provide an alarm when degraded
or irregular performance detected. The SG PMS solution is available as an upgrade on all
RV Steering
Gear installations completed in 2005 or later with KM Follow-up control system.
