[Maytham A340]

In the Aircraft there is two things that the pilot can use to do the taxing.
1- Using the Rudder Padels can let the aircraft to turn around 30 to 40 Degrees.
2- Using the NOSE WHEEL STEERING HANDWHEEL can turn the aircraft around 75 Degrees.

Some one will ask how to do the rudder CHK List when the pilot using the rudder Padels for the taxing? (Airbus) There is a button on the top of steering disk that disconnect the rudder padels. So you can do the CHK List without doing any turn.

In Boing I think there is a button that do the same function. Of course it's located some where.
