I’ve noticed a ton of people making jerky turns while taxiing. I’m nearly certain this is caused by the exponential being on displacement and not feedback. Essentially this means the null zone (even at the lowest setting) is too high. So people are trying to make turns using an unreasonably small control range. I think the initial intent was to help with takeoff and it is helpful to have some null area in the center. However the function seems way too steep (particular around the ± 50% area) which leads to a lot of ugly taxiing.
I’m anticipating: “it takes time to get used to it” or “you just need more practice”. I can assure you I’m pretty solid at it. However, it’s clearly a problem for a lot of people and is generally unrealistic. If anyone else has opinions on this I’d love to hear them!
