OK...I just read something about the "All-Flying Stab".
Now on to the technical description of the L-1011 pitch control system. The L-1011 incorporates an all-flying horizontal stablizer to control movement in the pitch axis. This "all flying tail" is unique in the commercial aircraft industry. First of all, pitch control on most airplanes are usually controlled by elevators - on the L-1011 however, the primary part of the tail that controls pitch is the front part called the horizontal stablizer, the leading edge of which which move up and down - the elevators are attached to the rear spar of this movable stablizer piece - the elevators do move, yes, but not under direct pilot control. The elevators move as a direct result of stablizer movement only via a physical mechanical link: When the stablizer moves it's nose downward, the elevators deflect upward to increase the camber of the entire tail - this causes a downward moment and thus pulls the entire rear portion of the aircraft in a downward direction - this causes the nose of the aircraft to pitch up. When the pilot pushes the control wheel forward, this causes the stablizer nose to move up, causing the elevators to deflect downward, increasing the camber effect to cause a lifting moment and thus pull the tail of the aircraft upward and this in turn causes the nose to pitch down.
IF THIS IS TRUE...then does the L1011 incorporate a Stabilizer Trim system??
