Attempt any one part of the following: 10 x 1 = 10
(a) Explain brie?y the various factors considered in the selection of site for airport.
(b) An airport is planned at an elevation of 380m above MSL. The monthly mean
of maximum and average daily temperatures for the hottest month at the site are
40?C and 28?C respectively. The effective gradient is 0.18 percent. Determine the
length of runway required at the proposed site if the basic runway length is 1900m.

(a) Explain the role of rail transportation in the development of a country
(b) In a layout of a B.G. yard, an 8? curve diverges from a 5? main curve. If the
maximum permissible speed on the main curve is 65 Kmph, determine the
restricted speed on diverging curve.
Attempt any one part of the following: 10 x 1 = 10
(a) What is a transition curve? What are the different types and what are the
requirements for an ideal transition curve?
