I don't believe any aircraft requires forward speed to operate the N/G steering. Will it skuff the tires? Probably, a little. I've seen greased sheets under the N/G tires in hangers during steering operation for maint. when the aircraft is not jacked.

Had a 727 recently move the nose gear back and forth to dislodge a couple chocks that a newbie put right under the tires and got lodged really good after making the aircraft about 50,000 pounds heavier than when we started with it. That didn't seem to cause any problems.

we have to be careful when doing our pushbacks! lately the tug crew have become very efficient in chocking the nosewheel whilst they disconnect the tow bar, if you pull out the bypass pin too quickly, before they remove the chock and the nosewheel isn't quite straight, it'll jam up a treat!

Thanks everyone. I knew the 747-200 tiller would turn regardless of speed, and assumed the 747-400 would too, but I couldn't be sure (no -400 data at the site I am at right now). The systems are very similar except for body gear steering arming, which is automatic on the 747-400, manual on the Classic.
Quoting Bri2k1 (Reply 5): I have actually seen this. It's the normal behavior on MS Flight Simulator.
You are very close to why I asked this. Although I spend my working days around training simulators, one of my hobbies is MS Flightsim (sad but true). A certain FS9 747-400 addon deliberately inhibits nosewheel steering when stationary. I questioned this and was told "it's correct, we checked". I expect they asked a pilot . (Apologies to the majority, but a few pilots seem to think that just because you shouldn't do something, it can't actually be done!).
A simulator should do what the aircraft does, not what the procedure tells the pilot to do, in case the procedure isn't followed properly.
The glass isn't half empty, or half full, it's twice as big as it needs to be.

My current personal copy is version 2004, and this is standard behavior on all included aircraft, including the single-engine Cessnas! I was fortunate enough at one time to have flown all the full-motion simulators in the United fleet, and I can confirm both tiller- and pedal-commanded steering works in the simulators exactly as it does on the real bird. I spent a lot of time trying to powerback a 777 in the simulator; I was never successful though.
