WHY WHEN I DISALBLE THE AUTORUDDER TO FLY WITH PEDALS  AS A REAL PLANE THE YOKE DOES NOT WORK ON THE GROUND?,CAN'T BELIEVE THAT THE BOEING FOR EX. SERIES WHEN YOU GOING TO THE GATES YOU HAVE TO USE THE AIR DIRECTION DRIVE, WHAT ABOUT THE FRONT WHEEL,AS I WAS TOLD THE PILOT SIT can MOVE IT, I MEAN THE FRONT WHEEL WHEN YOU ARE ON THE GROUND,AND NOT THE COPILOT.iS THERE AN OPTION THAT I IGNORE,TO set THE PLANE to WORK AS IT SHOULD BE

Unless in heavy wind the yoke is not used in ground taxi.  The aircraft is controlled by the pedals.  It's not a car.

If you have pedals then use those or if you have a joystick that can twist (I use Sidewinder Precision 2) you can use that.

LOL, no you're wrong. On the ground you steer the front wheel with a tiller, located to the left of the captain side.

On the runway, when you pick upp speed, the rudder is your primary tool for keeping the aircraft aligned :)

Here's a good picture of the tiller, which controls the steering of the nose wheel.

(and yes that's a B 777)

Thanks NEXUS 82  i knew the pilot was moving someting with his hand i presumed by that time that it was the yoke i was wrong  I hate when some call me in some sor of way a fool .Is this the only plane who has that tiller or other ways?    thanks  ;)

ok what you prob saw was flight control checks with the yoke. Now, the exact ways of turning on the ground are the tiller as nexus posted, for shallow turns the rudder pedals are used. the brakes are also another method for turning, but no the yoke cant be used as a method.

esa17,

You are correct in regards to small aircraft.  In smaller aircraft, particularly trainers, such as a cessna 172 etc., you steer with your feet on the pedals while setting the ailerons for the wind.

However, alrot was specifically talking about something he saw involving a 777 taxi techinique.  Boeings as well as all other airliners I'm sure are taxiid using a tiller like Nexus82 described.

I know that most business-class jets and larger have a tiller or wheel for ground steering. As stated above it's on the left of the pilot's position.

Many older fighters and many private A/C use differential braking for ground steering. Brakes are used one at a time to force the A/C to slew around the slowed wheel.

Newer small A/C use a nosewheel or tailwheel that is tied to the rudder system. Some fighters have a Nose Wheel Steering switch that the pilot must hold down to activate the NWS system. NWS is only available below a set speed (above which the rudder gains effectiveness).

I don't know of anyone that has done it...but there is no reason that a NWS system couldn't be tied to the yoke using a switch.
