Summary:
The full-time, dual-gain NWS system is designed
to provide adequate directional control in low gain
for normal and high-crosswind landings and takeoffs
while high gain provides increased nosewheel
steering range for aircraft parking. The rudder
pedals are used to control the nosewheels when the
NWS system is engaged. If NWS is deselected or
fails, differential braking can be used to steer the
aircraft. The NWS system is linked to the WOW
circuits and will not activate until weight-on-wheels
condition exists. Lowering the launch bar
deactivates the NWS, but NWS, +/- 20 degrees may
be selected by pressing and holding the NWS
button.
