Palestine International Airport (Al-Auja)

a- Longitudinal Profile of Right Taxiway

The profile for the centerline of the right taxiway was created in case that there is no

change in grade along the centerline. A grade of 0.54% is implemented along the

centerline of the right taxiway. The profile of the right taxiway is attached in the Appendix.

b- Longitudinal Profile of Left Taxiway

The profile for the centerline of the left taxiway was created and summarized in Table 7-

12 ; based on the standards listed in Table 7- 11 for the taxiway surface gradient. The

profile of the left taxiway is attached in the Appendix.

1 1+038.93 - 273.695 - 0.06% - 0.64% 150 0.58% Crest

2 1+753.70 - 278.249 - 0.64% - 1.21% 150 0.57% Crest

3 2+849.65 - 291.49 - 1.21% - 0.15% 150 1.06% Sag

Sample of Calculations:

− Minimum length of the vertical curve = 30 m for each 1% change in grade

− Minimum length of the vertical curve I = 30*0.588

= 17 m
