How many of them have steerable (rather than castoring) nosewheels Lfoppy Kiln?

If you land with a bootfull of rudder to kick the drift what's going to happen as soon as you lower the nosewheel? On "bigger" aircraft the nodewheel steering is disconnected from the rudder pedals in flight, and the nosewheel is either locked fore/aft or castoring. In either condition it must be physically disconnected from the rudder pedals. That's a complex kind of linkage to implement in a non-powered mechanical link - especially for a safety-critical item.

PDR
Most Cessna aircraft are nose wheel steered, the upper torque link when the nose leg is extended has a plate that sits against a flat on the nose leg strut locking it fore and aft, the nose steering rods have built in springs internally like a shocker strut, that allows the rudder pedal movement to collapse the nosewheel steering struts allowing for full rudder movement, when on the ground and the torque link / leg extension starts to collapse as weight comes on it comes off the leg stop, the forces required to steer the nose are less than those required to collapse the spring, so you have in effect solid steering rods and full steering and rudder movement..

Pipers such as the PA-28 have solid rods and the nose wheel turns with the rudder input if I remember correctly.
