The simplest method of scaling is linear. You take the input domain and stretch or squish it (if necessary) to fit the desired output range. For example you could convert a number in $`[-2^32, 2^32 - 1]`$ (joystick) to a number in $`[0, 1]`$ (percentage of thrust).

This is fine, but can be a bit "jumpy". It can be difficult to make small movements on a joystick, especially one on a relatively cheap controller (I'm sure airplane controls are a lot nicer mechanically). The linear scaling method leaves making precise movements up to the physical ability of the user and the controller.
