I only see one for drag, is there one for lift?

    The lift coefficient can be approximated by thin airfoil theory. That is, CL ~= 2 * pi * alpha for alpha in radians.

    D = Cd * A * .5 * r * V^2

    Cd = D / (A * .5 * r * V^2)

    @sacr3dbac0n0 also, I made a series of programs that can determine drag force in realtime using the equations for drag that look similar to what's below. The specific coefficient of drag for any craft can be found by letting it freefall through the atmosphere while running the calculations(this is the first of my programs. It works for any craft shape/size and in any atmosphere). Then you use the "average" drag coefficient to run the drag calculations in realtime(the second program). Using this method, I've gotten surprisingly accurate results, in fact nearly identical to the games own calculations. I haven't uploaded those yet as they're not quite finished to my liking, but I'll try to make them available soon. The equations for lift are very similar and could probably be calculated using a similar method, but I haven't tried it yet

    @YaMomzBox420 That's a very good suggestion. I definitely looked into it but didn't quite figure it out yet.

    @SamTheFox as a side note, that's nearly the same as the drag equation lol

    It's been a while, but not that I know of. If my foray into drag taught me anything there's an easier way to do that using what the game offers. Take the acceleration vector and subtract everything that isn't lift from it(gravity, drag, thrust, etc). You probably have to do some projecting of vectors, but if done right, the ONLY type of acceleration left will be from lift, and you can then convert that back into force units or whatever from there

    @SamTheFox Yes, but the other problem is the lift coefficient. It's a complex variable dependent on many factors, but the closest I got is C_L = 2 * pi * sin (AoA), which isn't ideal when using high-lift devices.

    there probably isn’t, but you can get the lift using traditional math:
    Lift = coefficient x ((atmo density x velocity squared) / 2) x wing area
