The stabilator and elevator are two very effective pieces of aerodynamic machinery. They are both found at the rear of an aircraft and both serve a similar purpose. Despite this, there are distinct differences between these two components of the empennage. An aircraft elevator is an example of a flight control surface, or an aerodynamic device which allows an operator to control the aircraft's altitude. It, along with the horizontal stabilizer, maintains the pitch, lift, and angle of attack of an aircraft. The aircraft stabilator, colloquially referred to as an all-moving or all-flying tail, is a one-hundred percent adjustable aircraft stabilizer. Essentially, the stabilator is a 2-in-1 device that performs the duties of both the horizontal stabilizer and elevator. Hence the name, stabilator.
