Most modern airliners do not have a stabilator. Instead they have an [[Stabilizer (aeronautics)#Conventional tailplane|adjustable horizontal stabilizer]] and a separate elevator control. The movable horizontal stabilizer is adjusted to keep the pitch axis in [[trim (aircraft)|trim]] during flight as the speed changes, or as fuel is burned and the [[Center of gravity (aircraft)|center of gravity]] moves. These adjustments are commanded by the autopilot when it is engaged, or by the human pilot if the plane is being flown manually. Adjustable stabilizers are not the same as stabilators: a stabilator is controlled by the pilot's control yoke or stick, whereas an adjustable stabilizer is controlled by the trim system.

In the [[Boeing 737]], the adjustable stabilizer trim system is powered by an electrically operated [[jackscrew]].<ref>{{cite book |title=Federal Register |date=July 1978 |publisher=Office of the Federal Register, National Archives and Records Service, General Services Administration |page=32404 |url=https://books.google.com/books?id=mSnOTEFOT2gC |access-date=18 October 2022 |language=en}}</ref>

One example of an airliner with a genuine stabilator used for flight control is the [[Lockheed L-1011]].
