Bug? Slip indicator

[Lau]

Hey everyone,

Noticed that the C101 does not require rudder inputs to keep the slip indicator centred. No matter the bank angle, the slip indicator remains pretty much centred without pilot rudder corrections.

Realistic or a Bug?

Thanks in advance for your feedback,

Best,

Lau

There is adverse yaw when applying aileron, you can see it in the displacement of the slip indicator ball. Since the C-101 has neutral lateral stability, once established in the desired bank angle, there is no need to apply aileron and therefore adverse yaw effect disappears.

I noticed there is still a tiny bit of adverse yaw even when ailerons are neutralized. Is this because the outside wing is moving faster in the turn, creating more lift, and hence more drag?

 

I tried one of my other modules, the F-86, and it actually behaves quite similarly. Apples and bananas, I know.

If that effect would exist would be negligible. What in fact exists is an adverse yaw dampening due to the yaw rotation, as the drag increases in the forward moving wing (this happens while there is some rotation around the longitudinal axis during banking).

There are many, more or less, decent explanations in internet for adverse yaw. Or you can download some book about aerodynamics. I can recommend you some if you PM me.
