Explanation:-
Answer : CDiscuss it below :Madan Bhusal Said on 2019-09-06 07:13:06
Length of runway after correction of elevation = 2000+140 = 2140m.
Difference b/n airport reference temp. and Std. temp. @ Elevation = 33.05-(15-0.0065*300) = 20 C
Corrected runway length = 2140+430 = 2570 m.
Applying correction for effective gradient at the rate of 20% for each 1% effective gradient, correction for gradient = (20/100*2570)*0.25/1 = 128.5 = 130m (Approx.) Actual length of runway = 2570+130 = 2700m. !! OOPS Login [Click here] is required to post your answer/resultHelp other students, write article, leave your comments |
