How do mechanical side sticks compare to fly-by-wire side sticks?
This question might seem kinda odd and weird by the title, but I wanted to know something regarding the mechanical side sticks, such as ones used in the Cirrus Vision SF50, Eclipse 500/550, Cessna TTx etc.
My first question regarding them would be the fact that side sticks don't have much leverage and would compensate that by being more sensitive, with smaller deflections leading to larger elevator deflections. Airbus (/other FBW side sticks in general) did it with their C*/C*U algorithm mixing in pitch rate and g-demands at different speeds/altitude to give somewhat of a same feel at different flight conditions. So a FBW side stick deflection at high speeds at high altitude would give the same output as it would in low speeds at low altitudes, and u won't end up with an extra twitchy control stick at higher speeds.
How did Cirrus/Eclipse Aerospace deal with this issue? Considering that the side stick (that has a very small deflection area) is physically connected to the cables/push-rods, wouldn't it be an issue to have an already twitchy control stick to be super twitchy at higher speeds?
My second question is for pilots who flew both FBW aircraft equipped with side sticks and these GA aircraft equipped with mechanical ones, what are the general differences? In term of feeling and general flight-handling characteristics.
The main point of my post is trying to understand the difference between fly-by-wire side sticks and manual push-rod/mechanical side sticks. There's a lot of threads here regarding older mechanical yokes and newer Boeing fly-by-wire yokes, and their comparison, but not much regarding side sticks, so I wanted to create one!
