An airplane caught in turbulence moves both as a whole body and as a flexible structure, Pettit said: “It’s sort of mind-blowing, the number of ways an airplane can bend and twist.” To compensate for all that jouncing and twisting, the flight-control software uses the plane’s sensors to calculate the force and direction of the wind. Then it moves the flaps on the wings and tail to counteract the pressure. “Say the airplane is bending like a yardstick,” Pettit said. “The elevator”—the horizontal flap on the tail—“can move to oppose that. Or the rudder will stop it from moving side to side.” If the plane heaves up, the spoilers can press it back down. If it drops, the wing flaps can lift it up. If it starts to roll, the ailerons can right the ship.
