Figure 1. This plot illustrates a Boeing 737-800 takeoff simulation on a smooth runway. Notice that all of the aircraft accelerations are plotted within the +/-.40g red bands.
Figure 2. This plot illustrates the predicted aircraft response when a Boeing 737-800 performs a takeoff operation on this runway with areas of roughness. This technology shows that there is a roughness event located around 750 feet past the runway’s threshold.
