Salute!

Thanks, Cland......

What a lotta folks do not understand about FBW is that it can be implemented with zero computer help. It can be a simple pair of wires to a control actuator that replaces levers, pulleys, cables, pushrods, etc. Most FBW systems have a hydraulic source that the wires activate or control. But some are now being flown that use the electricity in the wires to move the control surfaces, and the new F-35 is one of those.

What the FBW system architecture allows is sorta like a cosmic autopilot with all kinds of "help" to reduce workload and make for a smooth flight. For example, flying thru bumpy air is smoother because the rate and gee sensors act very quickly to command the surfaces before a human could react. The Viper felt like a much bigger and heavier plane when down low on hot days with thermals all over.
