Another beginner Q
I remember seeing a button on the A320 flight deck for disconnection of
the nosewheel steering control. I also remember the cap'n saying that that's used during the push-back of the aircraft. He mentioned some reason for that but I don't recall what; possibly something to do with the hydraulics not getting accidentally triggered off or something like that. Can someone get me up to speed on this? Cheers, Ramapriya |

for all of your questions... you are concentrating on the A320... why not
smaller aircraft that you could be learning to fly in? Every "airliner" or large aircraft, the nosewheel steering control will be different in some fashion. Older airliners actually had a "tiller" on the cockpit left side wall. My nose wheel control switch actually had different functions, on the ground, it would engage nosewheel steering control to the rudder pedals, in the air, it would (a) select transponder ident feature (b) during air refueling it would disconnect the AR boom.. just to name a couple of things.

Can someone get me up to speed on this? I can't say for certain, but I can probably make a pretty good guess. During push-back the airplane is moved backward via a tug and towbar attached to the nose gear. The nose gear must be free to turn to permit the tug driver to steer the aircraft. The nose wheel steering system would tend to resist his efforts if it was engaged. |

I am not familiar with the 320, but all large aircraft have hydraulic steering. Usually, the scissors are disconnected prior to towing, but that company may elect not to for push back. In any case, it is most likely a safety issue as bumping the tiller or rudder fine steering while someone is trying to handle the tow bar or hook up the scissors could make them loose some body parts. Some Boeings I am familiar with have a switch above the nose strut so the tow person can turn off the steering for the same reason.

BTW - I'm sure there are others who frequent this site that are like me. I work in the large aircraft world and play with the small ones. I welcome any large aircraft questions and I'll be the first to ask about the small ones. There are no stupid questions with the exception of the un-asked one.

And chances are that, although I've fervent interest in aviation, I won't get to fly *anything*, with my personal financial position, as stated earlier here. That's possibly why many don't respond to my idle Qs these days Cheers, Ramapriya |

Isn't this simply because during 'push back' the towing bar is locked to the nose wheel so that the tug can turn the aircraft as is pushes it back? Otherwise the nose wheel steering could be damaged by the tow. -- David CL Francis |

I remember seeing a button on the A320 flight deck for disconnection of the nosewheel steering control. The nose wheel steering can overpower the towbar. That can cause the towbar to break, or the airplane to break, or the human operator to break. On some other types of aircraft, the nose wheel steering is disconnected when the rudder gains authority with airspeed. D. |
