Thrust-vectoring was enabled through the use of the Axisymmetric Vectoring Exhaust Nozzle (AVEN). The X-45A introduced yaw axis thrust vectoring. The Su-30MKI and MiG-35 feature thrust vectoring engine nozzles to enhance maneuvering. The aircraft features 3-D thrust vectoring capability. The missiles are steered with a combination of control fins and through thrust vectoring vanes. Attitude control relies purely on 3D thrust vectoring. The aircraft featured fixed engine nozzles, instead of thrust vectoring nozzles as on the YF-22. This lateral distribution of torque is commonly known as torque vectoring. PAVE was later used as an acronym for Precision Avionics Vectoring Equipment. It has a booster with thrust vectoring capability. All four wheels are individually controlled by the Porsche Torque Vectoring system. Jet packs and flying platforms are steered by thrust vectoring only. This is paired with an Active M-Differential with torque vectoring between the rear wheels. Jet skis are steered by weight-shift induced roll and water jet thrust vectoring. The term PAVE stands for Precision Avionics Vectoring Equipment.
