Stick deflection limiter override

[Martin2487]

Stick deflection limiter override default bind on the Y key. Could someone explain its function and where this button is located in the aircraft? If I understand correctly, its function is to enable override of the angle of attack limitation system. Was there something like this in a real airplane? I thought this system could be overridden with the control stick. That's why I was surprised to see a button here. Thanks for explaining.

It’s not a button. It’s simply a bind to simulate pressing through the AOA limit which takes about 17 kg of force.
