This is an accurate simulation of the way the real aircraft’s elevators and ailerons function. 

The elevator and ailerons use servo-tabs for the elevator (they look similar to trim tabs) and the flight controls only directly affect the position of those tabs. Once airflow increases over the elevator during the take-off roll, the tabs will take effect and the elevator will move to the commanded position.

These control surfaces respond to wind, turbulence, up-drafts, cross-winds, etc.
