Simply because it's impossible, but if it can move faster than our simulator
rate, then it does not matter. Or was t

Yup.
And that's not limited to little Cessnas, either. Additional
examples to illustrate the same point include:

In general, then, as others have mentioned, this belongs in the flight
models rather than the input layer. The input layer *requests* a

When prssing the 5 key on the numeric keypad to reset the controls to zero,
the control surfaces instantly move to their origin. Similar effects can also
happen when an autopilot controller is activated, and when a noisy joystick
is interfering with an autopilot controller.
