Pressure-reduction and cascading-set-point calculations use the same adjusted power and airflow equations. The exponent 0.283 is the legacy pressure-power relationship retained by this assessment.

\begin{equation}\label{eq:compressor-eem-pressure-power} P_{adj} = P_{FL} \frac{\left(\frac{P_{adj,FL}+P_{alt}}{P_{alt}}\right)^{0.283} - 1} {\left(\frac{P_{FL,g}+P_{atm}}{P_{atm}}\right)^{0.283} - 1} \end{equation}

\begin{equation}\label{eq:compressor-eem-pressure-airflow} Q_{use,adj} = Q_{use} - \left(Q_{use} - Q_{use}\frac{P_{adj,FL}+P_{alt}}{P_{FL,g}+P_{atm}}\right)0.6 \end{equation}
