pi&-)
Failure to cycle nosewheel steering following
hook check will enable nosewheel steering
centering to remain engaged and can
cause mispositioning of the launch bar during
catapult hookup. This may result in
launch bar disengaging t?om shuttle during
catapult stroke.
7.4.5 Taxiing. To set the aircraft in motion starting
fivm a static position requires advancing the throttles
slightly. While departing the line area, flightcrew should
clear the extremities of the aircraft and the wings should
remain at 68’ or in OV SW to minimixe the span clearance.
Once in motion, IDLE thrust is normally sufficient
to sustain taxi speeds and full nosewheel steering
authority may be real&d.
7.4.5.1 Taxi Speed. Taxi speed should be maintained
at a reasonabler ate consistentw ith traffic, lighting,
and surfacec onditions. Subsequentto flight, while
returning to the line at light gross weights, one engine
may be. shut down to prevent excessive taxi speeds at
IDLE thrust
Before taxiing aim&with wings in oversweep
and full wing fuel tanlm, trim stabilizer
to zero to prevent wingtip and
stabilizer interference.
When taxiing across obstacles ensure
nosewheel is centered to preclude launch
bar from impacting nose wheelwell doors.
To prevent overheating, do not ride the
wheelbrakes.

Note
When shutting down one engine during taxiing,
the right engine is normally shut down
so that normal braking is maintained.

system is not operative. The nosewheel steering can mmain

wheelbrakes in conjunction with nosewheel steering
should be pertormed symmenically to minimixe nose tire
side loads. In minimum radius turns (Figure 7-3) using
nosewheesl teering,t he inboardw heel rolls backward as
the axis of rotation is between the main gear. Because
of the distance from the cockpit to the main landing
gear, the pilot should make allowance for such in turns
to prevent turning too soon and cutting comers short.
7.4.5.3 Crew Comfort. Crew comfort during taxi
operations is affected by the nose strut air curve characteristics,
which maintains the strut in the fully extended
(stiff strut) position except during deceleration. Because
of the wide stance of the main gear, differential application
of wheelbrakes is effective for turning the aircraft
without the use of nosewheel steering.
l On-deck engine operations for extended
periods can result in an unacceptable
buildup in fluid temperatures (hydraulic,
engine oil, and IDG oil) by taxiing heat
exchanger capacities. Since the letI LDG
supplies the majority of the electrical
power, it is more susceptible to overheating
than the right. Tail winds or large
power demand, or both, at high ambient
air temperatures increase the chances of
fluid overtemperature.
l Since the outboard spoiler module is automatically
energized with the flap handle
down and weight on wheels, it is necessary
to restrict the amount of flaps down
operation on the deck to prevent module
fluid overheating.
7.4.6 Taxi - Pilot
Taxiing with the left engine secured is not
authorized. Normal braking and nosewheel
steering control will be lost if the hydraulic
transfer pump (BIDI) fails while taxiing with
the left engine secured.

2. Nosewheel steering -Check.

Check control and polarity in static position before
commencing to taxi.
