TAS \approx IAS + (IAS \times 0.02 \times \tfrac{alt}{1000})

Quick estimate: true airspeed increases about 2% per 1000 ft of altitude above indicated airspeed.

GS = TAS \pm W

Ground speed is true airspeed adjusted for the headwind/tailwind component.

TAS \approx IAS\left(1 + \frac{h}{60000}\right)

Airspeed corrected for altitude.

r = \frac{\rho_c\,h}{\rho_m - \rho_c}

Depth of a mountain's crustal root floating in the mantle.

S = \frac{1}{(1-p) + p/s}

Maximum speedup from parallelizing a fraction of a task.
