Not necessarily. This depends on:
- Whether the F/O has a tiller. On smaller aircraft there may be only one tiller. For example, the DC-9 (including the -80 marks) has only a Captain's side tiller.
- Company policy on whether the F/O may taxi.

Quoting Tom12 (Thread starter): I was looking through the DB and came across an Air France 777 cockpit shot. The F/O has his hand on a 'Triller' /... i'm sure it said Triller below it.
The tiller is use for nose wheel steering you can also use the rudder pedals (but the nose wheel does not turn that much). When i taxi i use the rudder pedal to keep the airplane straight when i am turning i use the tiller.I also like using the engines to help also if i am turning left i increase the power of the engine on the right the airplane just seems to turn easier.

Quoting 744rules (Reply 12): note that automated docking systems are calibrated on the left hand seater. I suppose that when f/o is taxiing in, he'll get instructions from the captain
The new laser NIGS appearing around the world use aircraft geometry not the Captain's eyeline for guidance so either pilot may use it. Our company policy is still for the Captain to park the aircraft, even under hand marshall. Normally the FO will hand over once aligned with the gate.

Quoting Zenarcade (Reply 15): Is the tiller system all hydraulic with "power steering", or is it by wire somehow? I can't imagine there not being some sort of power assist, imagine the elbow grease it would take to steer!
This is for a 757/767 you have hydraulics and cables.Whether the nose steering is from tiller or rudder system.The command signal is transmitted by cables to a hydraulic metering valve located on the nose gear.The metering valves(you can put it in bypass to stop hydraulics going to the acuators usually done when towing the airplane push back etc) direct hydaulic pressure to two steering acuators to steer bose wheel.They are quite a few things involve in nose wheel steering.Two sets of control cables(tiller+piston position) two steering actuators,steering collar,steering metering valve summing mechanism and broken cable compensator,rudder pedal steering interconnect mechanism,torque limiter and a steering tiller.I have had to rig a nose steering system and they are a pain not a job i usually volunteer for.

heres a question:
ive always wondered how many rotations it takes from the tiller to make a hard turn with the nosewheel at maybe 70 or 80 degrees. or does it not work that way? just a simple turn to the 9 o'clock position is full left and 3 o'clock full right?

From the 767 manual: Nose Wheel Steering Tiller
- turns the nose wheels up to 65 degrees in either direction
- overrides rudder pedal steering
The tiller simply goes 90 degrees (approx) left and right for full lock. Letting it go during a turn can floor every standing FA in the aircraft so the tiller must be held in the required position when out of centre.
The rudder pedals give 7 degrees of nose wheel steering, which is fine for taxying on straight runs, taxing rapid exit/high speed taxyways nd during most takeoff runs.

Useless fact of the day:
The Mooney M-20R Ovation's nosewheel can steer thirteen degrees to the right, but only eleven degrees to the left. This equates to an eight foot difference in minimum turning radius, and is a good thing to know when maneuvering on the ground.
