AUTOMATIC SHUTOFF THROUGH THE SPEED SWITCH
During normal operation both systems are powered at speeds below
135 KIAS. Above 135 KIAS, Rudder System 1 is automatically shut off.
If the automatic shut off fails to shut off a system above 135 KIAS, a
caution message is presented on the EICAS. In this case, it is
necessary to manually shut off system 1 or 2, according to the
checklist.
If Rudder System 2 hydraulic power supply fails, Rudder System 1
automatically takes over the rudder and an associated caution
message is presented on the EICAS.
RUDDER HARDOVER PROTECTION
The rudder hardover protection function automatically selects the
mechanical reversion mode as a function of pedal input force, rudder
deflection, and airplane engine operation (two or single-engine
operation). This feature was designed to activate in case of a runaway
rudder and a caution message is presented on the EICAS.
The rudder systems are automatically shut off if all conditions below
are met simultaneously:
−
Rudder deflected above 5°±1°.
−
Force above 59 kg (130 lb) on the pedal to counteract rudder
deflection.
−
Both engines running above 56% N2.
CAUTION: DO NOT RESET THE RUDDER SYSTEMS IF THE
MECHANICAL REVERSION MODE WAS RESULTANT
OF A RUDDER RUNAWAY FOLLOWED BY THE
HARDOVER PROTECTION ACTIVATION.
If mechanical reversion mode was not resultant of a rudder runaway
followed by hardover protection activation, a reset function is available
on the Overhead Panel, by pressing both Rudder Shutoff Buttons off
and on again.
The following remarks are applicable to the rudder hardover
protection:
−
The signal from the Pedal Spring-Loaded Cartridges to shut off the
rudder systems are applicable only if the pilots are applying force to
one side with the rudder deflected above 5° ± 1° to the opposite
side. If pilot command input and the rudder deflection are in the
same direction, the system will not be shut off, regardless of how
strong the pilot input.
