This study was designed to determine the effect of considering variations in pressure altitude on required runway lengths and take-off weights. Meteorological data representing actual conditions at specific locations were examined and the recorded values of barometric pressure and temperature were used. Values of barometric pressure were then converted to pressure altitude and assumed values were used for take-off weight, runway slope, and wind. The required runway lengths resulting from computations for each aircraft in each airport were plotted on probability paper as families of curves. These curves were the source of data from which the conclusions were drawn. While variations in pressure altitude greater than 500 ft have been found to occur only infrequently, no published data are available showing the effect on runway lengths of pressure altitude. This study shows the magnitude of the effect of including pressure altitude.
