How does the AngleOfAttack work as an input (Funky Tree)? It seems that the parameter works improperly.

Is there anybody knows that in what way the parameter get the value of AOA?

I knew it is the "angle airflow vertically meets the boresight",

but the value it returns is not able to match with the value provided by the showAOA plug-in.

    You should use clamp01(-AngleOfAttack < 20) instead

    @jamesPLANESii and the value returns by the AngleOfAttack is described as AngleOfAttack - The angle of attack (angle airflow vertically meets the boresight) in degrees, which makes me quite confused (especially the "in degrees") in this situation that the AngleOfAttack<20 work improperly.

    @jamesPLANESii may be, but here comes another question: AngleOfAttack<20 won't work at all as a Boolean expression(or FT expression).

    Ah ok lol. I guess do -AngleOfAttack @Maiqu
    Does that solve it?

    @jamesPLANESii Thanks again, but I knew the definition of AOA.

    @jamesPLANESii Thanks, but the question is about the value returned by the parameter AngleOfAttack. It returns a negative value while the showAOA plug-in returns a positive value.

    Basically the angle the wind hits the plane in the pitch axis.
    It’s useful to know with stalling. Planes stall at the same AoA no matter the speed.
