What Moves The Nose Gear?

Sun Aug 13, 2000 3:52 pm

What moves the nose gear on the ground (when aircraft is stationary, taxing, and rolling)? The nose wheel tiller or the rudder pedals?

The short answer . . . YES, the long answer, yes and no!

On some aircraft it is controlled by the rudder petals, on some it is controlled by a tiller. I'm not sure but on some a/c I think it can be selected. JETPILOT - little help here?

It depends on the situation.

If the aircraft is rolling on the ground at high speeds (i.e. during take-off and landing) the captain (or F/O) will steer the aircraft with the rudder pedals. Nose gear turning angle is in this case limited at 7.5 degrees left and right. The rudder moves along with the movement of the pedals.

If the aircraft is taxiing the tiller will be used. The nose gear can now be turned as far as 60 degrees left and right. The rudder does not move along with the wheels now. An indicator on the tiller shows the pilots the position of the nose gear.

On the 727 both the rudder pedals, and the tiller control the nose wheel sterring. Both at the same time. the rudder pedals for small adjustments, and the tiller for large direction changes. Or the tiller for both.

The tiller controls a large degree of movement while the rudder pedals contol 7 degrees left or right of center as previously mentioned.

Is it possible to steer the airplane with rudder pedals ONLY on the ground?

Can you confirm that when rudder pedals are used on the ground to move the nose gear, the rudder itself moves?

Dear Koopas,

Can you narrow your questions down to a specific aircraft type? Every aircraft is designed differently and may or may not behave similarly in similar situations.
Moving the rudder pedals on the ground should move the nosewheel steering on most airliners. The rudder should move on B757/767 aircraft and should not move on MD80/90 aircraft (without a whole lot of wind).

The answer is both. When on the ground, the rudder has limited control of the nose gear, depending on type of aircraft. The MD-11 rudder gives you up to 10 degrees of steering on either side. The 737 gives you 7 degrees. More than that, pilot must use the tiller.
