Fyi there is one pedal on each side of the steering column.

Thank you. So there's a little art to the maneuvering of the foot to push the top for braking action, and full on for the rudder.
Check (for pedal on each side). I don't think I worded that correctly, was thinking there was an inner/outer pedal, but I get it now! Thank you!!

There's a little art, yes, but it isn't super difficult. The PF will typically have his feet "up" on the rudder pedals for taxi. You can then pivot your foot forward to brake (pressing the top of the pedal to pivot it) and push with your heels to steer. The pedals are interconnected, so when you push on one pedal to steer, the other pedal will move towards you, and vice-versa. (The other pilot's pedals move in sync.)
On the take-off roll, in the air (with the autopilot off), and on landing, you'd keep your feet "down" with your heels on the floor, so that you can push to steer, but you can't brake. On the landing roll, you'd move your feet "up" once you want to start braking and take out the autobrake if you have one. (In a large jet, you don't use the rudder pedals in the air except on landing or with an engine out, as the rudder is automatically handled by flight control system.)
The PM would normally keep his feet "down" at all times, except when coming up to the bay, when he would "guard" the brakes in case of incapacitation or malfunction.
Larger aircraft also have a tiller, sometimes only on the left side, but typically on both in modern designs, which is used for bigger nosewheel deflections. IIRC, the max steering deflection with the pedals on the A330 is 7 degrees each side, while max with the tiller is 72 degrees each side. So you'd use the tiller for taxi turns, and the pedals for take-off, landing, and staying straight on a taxiway.
Some smaller aircraft have no nosewheel steering at all, and are steered by using differential brake pressure. The nosewheel is castoring (free rotating) like a shopping trolley wheel. Tailwheel aircraft have no steering either, and also use differential brake pressure.

Well described and agree with all that
Still, there’s a vocal minority of pilots who believe in having their feet ‘up’ on the rudder pedals (heels off the floor) during takeoff, they rationalize this with the belief they can start braking earlier in the event of an RTO
Regardless of the risk of inadvertently applying brakes as the aircraft is accelerating

Slight correction about a free castering nosewheel - you use differential braking to steer at lower speeds and in tighter spaces, but at RPMs where the rudder is effective (about 1000+, or the traditional "brisk walk")), you just use the rudder and save the brakes.

I'd really like to see them react faster than the autobrake.
And even if there's no autobrake, this seems like a good way to embarrass yourself. Minor birdstrike which is no cause for an RTO and you might reject before thinking it through.

Thank you for the generous response. The center of the bottom of a pilot's foot is the pivot point on the pedals. Do I have that right? Is it fairly comfortable and easy to get used to position?
Also - during taxi, I often see the rear rudder on the tail fin move back-and-forth on other planes taxing. Is that done with pedals or the yoke? Thanks!

However this is not an issue as long as you reduce power to idle immediately, this along with initial rudder input will keep you on the runway
At my airline the policy was always ‘heels on the floor’ for take off but there’s a few who adamantly disagree

As there are no cables and pulleys attached to the pedals on the AB, is there a similar feature like the sidestick priority button for the rudder pedals? What happens on the AB if one pilot inputs full right rudder and the other pilot commands full left rudder? In a Boeing, I would assume the pilot with the stronger foot will win. In an AB, both potentiometers connected to the pedals will measure full scale deflection. Would they just cancel each other out, and the rudder remains centred?

What happens on the AB if one pilot inputs full right rudder and the other pilot commands full left rudder? In a Boeing, I would assume the pilot with the stronger foot will win. In an AB, both potentiometers connected to the pedals will measure full scale deflection. Would they just cancel each other out, and the rudder remains centred?
There are no cables and pulleys going to the rudder actuators, but the two sets of pedals are still mechanically connected just like on Boeing. So if one set moves, so does the other.
Stronger foot wins.

And since rudder and trim wheel were the last stage of fallback in case of FBW failure on earlier airbuses... Does that mean FBW is now recognized as reliable enough to have no mechanical fallback option?
