Q1:

The runway length after correcting for elevation and temperature is 2845 m. If the effective gradient on runway is 0.5 per cent, then the revised runway length will be

A 2845 m

B 2910 m

C 3030 m

D 3130 m

ANS:D - 3130 m

Correction for gradient = (20/100)x2845x0.5 = 284 m.

Corrected runway length = 2845+284 = 3130 m.
