gums - thanks for your response. I sent my last post before seeing yours. I find no fault what so ever with what you have presented. Having been fortunate to be involved in design of fully FBW systems I fully agree that when handled properly, that is a better direction. Use of a very slow control surface to make up for a phugoid related aerodynamic short coming is one thing. Use of that same very slow control surface to make up for a short period related aerodynamic short coming is something else. One of my goals is to see to it that enough of the design community learns these expensive lessons so that future editions of control systems on current and yet to come models behave both on their own and in conjunction with pilots in a robustly predictable and safe manner.
