**drwls**, Wednesday, May 27, 2009 at 11:10pmThe horizontal component of the lift force equals the centripetal force and the vertical component equals the weight, M g.

C*A (1/2)(rho)V^2 sin 40 = M V^2/R

C*A (1/2)(rho)V^2 cos 40 = M g

C is the lift coefficient and A is the wing area. "rho" is the air density.

Divide one equation by the other to eliminate a lot of unknowns.

tan 40 = V^2/(gR)= 0.839

R = 1.192 V^2/g

Be sure to convert V = 430 km/h to m/s before using the formula. g = 9.8 m/s^2
