Accessing from parent object a method from a script component located on a child

Question

I've got an object player on which I've put a child which contains only a script casting a line to detect if the player is grounded. I'd like to get the result of this linecast in my playerControls script (component of player). To do this i've made a public methods that returns the result of the linecast, but I don't know how to make a reference to the script to call the method.

How can I do ?

 hingeJoints = GetComponentsInChildren<HingeJoint>();

If you only have one player you can also use a Singleton pattern. But the easier solution is to get the component of the child.
