b- Longitudinal Profile of Left Runway
The profile for the centerline of the left runway was created and summarized in Table 7-
7 ; based on the standards listed in Table 7- 5 for the runway surface gradient. The profile
of the left runway is attached in the Appendix.
Table 7 - 7 Details of the Left Runway's Longitudinal Profile, in m
Curve PVI Station PVI Elevation Grade In Grade Out Vertical Curve Length(m) (Grade Change)A^ Curve Type
1 1+500.88 - 270.264 - 0.07% - 0.80% 430 0.73% Crest
Sample of Calculations:
− Minimum length of the vertical curve = 305 m for each 1% change in grade
= 305*0.73
= 223 m
