Airport planning and design for civil engineering B.E/B.Tech- model question paper


1(a) Explain in brief the growth of domestic air traffic in India. (6 Marks)
(b) Write a short note on B 747-400 Aircaraft KONARK. (4 Marks)
(c) Explain in detail the influence of air craft design on runway length. (10 Marks)
2 (a) Explain how the movement of an aircraft is controlled by the pilot. (10 Marks)
(b) Mention the advantages of jet engines over conventional engines. (4 Marks).
(c) Discuss in brief the future requirements and trends in the aircraft design. (6 Marks)
3(a) Mention the various factors to keep in mind during the selection of a site for an airport. (6 Marks)
(b) Discuss the effect of noise on airport planning. (6 Marks)
(c) Sketch a typical topographical map for an airport which is planned for two parallel runways. (4 Marks)
(d) Sketch a typical master plan of the airport which is to be developed in three stages. (4 Marks)
4 (a) Explain with neat sketches the limiting heights of objects in the approach and turning zone of an instrumental runway. (12 Marks)
(b) The runway length required for landing at sea level in standard atmospheric conditions is 3km. Runway length required for take-off at sea level in standard atmospheric condition is 2.5 km. Aerodrome reference temperature is 25 degree centigrade and that of the standard atmosphere at aerodrome elevation of 150 m is 14.025 degree centigrade. If the effective runway gradient is 0.5 percent, determine the runway length to be provided. (8 Marks)
5 (a) Define the term gate capacity. Explain the factors on which the gate occupancy time depends. (8 Marks)
(b) Discuss the principles of design of runway intersection area. Draw a typical sketch showing the gradation of the intersection area. (12 Marks).
6 (a) Explain in detail the various factors which affect the layout of taxiway. (8 Marks)
(b) Write a short note on optimum location of exit taxiway. (6Marks)
(c) Determine the radius of a taxiway for a supersonic transport whose wheel base is 35 m and the tread of main landing gear is 7.2m. The design turning speed is 60 kmph. Assume any other data, if required. (6 Marks)
7 (a) What is ESWL? How can it be determined for dual and dual-in-tendem wheel assembly? (6 Marks)
(b)  Name and discuss in brief the various methods used for designing flexible airport pavements. (10 Marks)
(c) An existing runway and taxiway consists of 15 cm of cement concrete slab resting on subgrade. The subgrade soil is grouped as Rb type. It is necessary to strengthen the pavement for supporting ESWL of 26300 kg. Determine an overlay thickness of bituminous concrete. (4 Marks)
8 (a) What are the broad principles kept in view for the convenience of passengers and baggage flow in terminal area. (4 Marks)
(b) Explain the necessity of airport lighting. (4 Marks)
(c) Enumerate the various criterias for designing the filter material for sub surface drainage. (6 Marks)
(d) Discuss in brief the various aspects of environmental management and monitoring programme needed after the airport is in operation. (6 Marks).
