Step 5 – No temperature adjustment, since the chart is valid for all temperatures.
Step 6- Adjust the obtained length since the Airport Planning Manual (APM) provides only
the dry runway condition, so increase the obtained dry runway length by 15 percent.
Wet Runway Length = 6300 + (0.15*6300) = 7,245 ft.
Note: Round lengths of 30 feet and over to the next 100-foot interval. Thus, the landing
length for design is 7,300 feet.
The landing field length is 7,300 feet (2,225 m).
