             One example of metallurgy is in the design and function of the
             horizontal stabilizers found on all modern jet airliners. They function to
             adjust the wing's aerodynamics by moving the horizontal stabilizer up or
             The pilot sets the trim with split switches after the plane takes off.
             The safety of this lies in the center of gravity that is largely dependant
             on how much weight is on the plane. If the load planning dept. has carried
             out accurate calculations then it takes very little effort for the pilot to
             lift the plane off the ground, after the takeoff safety speed has been
             reached, by pulling back on the yoke. While the plane is under
             acceleration in the sky, the pilot continues to make pitch trim adjustments
             by pressing up or down on those split-switches on the yoke. This is done
             because the amount of force, applied is directly prop
