They lacked statements to support functions such as scheduling of processes. 16 Effectors and Actuators The last enabling technology for fly-by-wire flight control consists of the actuators that move the control surfaces. In the mechanically based flight16 Reilly and Prince, “Relative Merits,” p. 210. 27 control systems, the control surfaces move under direct-cable positioning. This is replaced by electrical connections to actuators in fly-by-wire systems. In fact, the original meaning of “fly-by-wire” is limited to this technology alone.

16 region it gained significant stability simply because the fins were moving through air. Even though it is now quite practicable to design a rocket control system that does not depend on aerodynamic assistance, relatively few are built that way. Generally, the fins are used, except in cases where they are more trouble than they are worth, such as in silo-launched intercontinental ballistic missiles. In the case of missiles intended for atmospheric flight, such as air-toair weapons, the fins are one of the effectors of the control system.
