Total Distance to Clear 50-Foot Obstacle (7 interpolations required)
The interpolations required are identical to the ground roll interpola-
tions, except "total distance to clear 50-foot obstacle" values are substi-
tuted for the "
groun
d roll" values.
The interpolated value for the total distance to clear 50-foot obstacle
is 2021 feet (no wind) and 1791 feet (19-knot headwind).
