Detailed Description

A class that calculates the altitude from the pressure values, using the ICAO 1993 standard. Altitude Calculation is different for when the tempreature gradient, beta is zero versus when not. When beta != 0:

\begin{eqnarray*} H = H_b + \frac{T_b}{\beta} ((\frac{P_b}{P})^{\frac{\beta R}{g_0}} - 1) \end{eqnarray*}

When beta = 0:

\begin{eqnarray*} H = H_b + \frac{RT}{g_0} ln({\frac{P_b}{P}}) \end{eqnarray*}
