Something else that may be interesting for the true geeks out there. Some planes, like the 727, use balance tabs which reduce aerodynamic load on the surface. However, if hydraulic power is lost, the balance tabs will now work as boost tabs, since it would be very difficult for the pilots to manually move the control surface, they just move the tab, which aerodynamically moves the flight control surface.
