NWS Operation
Nose Wheel Steering
Operation
a.
NWS on all the time in low gain
b.
NWS high gain selected with NWS button
c.
Emergency off by pressing paddle switch
d.
NWS disabled when launch bar extended, + 20
degrees NWS available if NWS button pressed
and held
NOTE: High gain nosewheel steering should
be used for low speed taxi operations only at

Operation
b.
Brake control valve: supplies HYD 1 hydraulic
pressure to operate wheel brakes whenever the
brake pedals are depressed, the parking brake
is engaged, or upon command from the de-spin
actuator

selected and excessive wheel deceleration is
sensed (impending skid), directs pressure to the
return lines, thus releasing the brakes
d.
Brake unit: transmits HYD 1 hydraulic pressure
into mechanical energy required to stop rotation
of main gear wheels
