So, consider the jet is being fly, where the jet will point by activating such elevator? Which axis will be affected. I assume the pitch (up) and the roll (to the right) axises will be affected. I am not sure about yaw axis. | |

Stabilator is also common but there is a considerable difference in operation between a PA-28 or C-177 stabilator and that found on say an F-16. | |
| Sep 5, 2019 at 13:00 | comment | added | Romeo_4808N | @Tanner Swett It depends on the speed and flight profile. Ailerons offer good roll authority in Low subsonic flight while differential spoilers and all moving tailplane work better in high subsonic and supersonic flight regimes. I’d say differential spoilers offer the best roll authority but combinations of control surfaces are frequently used to increase maneuverability and maximize control authority. | |
| Sep 5, 2019 at 12:04 | comment | added | Sophie Swett | Is it more efficient to use differential elevator deflection for roll (in addition to the normal use of elevators and ailerons) than to use the elevators only for pitch and the ailerons only for roll? | |
| Sep 5, 2019 at 12:03 | comment | added | user14897 | For completeness, that surface in question is a stabilator, not an elevator. | |
