s^2 = \frac{1}{n-1}\sum(x_i-\bar{x})^2

Unbiased estimate of population variance.

Error = Bias^2 + Variance + \sigma^2

Total expected error decomposes into bias, variance, and irreducible noise.

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.

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

Airspeed corrected for altitude.

f_s \geq 2f_{max}

Minimum sampling rate to capture a signal without aliasing.
