R = \frac{v^2\sin 2\theta}{g}

Horizontal distance of a projectile on level ground.

r_s = \frac{2GM}{c^2}

Event horizon radius of a black hole.

GR = \dfrac{d}{h} = \dfrac{L}{D}

Horizontal distance traveled per unit of altitude lost equals the lift-to-drag ratio.

GR = \frac{\text{horizontal distance}}{\text{altitude lost}}

Distance traveled forward per unit of height lost.

h \approx \frac{d^2}{2R}

Approximate drop of the horizon over distance d.
