1. DEPARTMENT OF CIVIL ENGINEERING Factors in Airport Site Selection, Airport Size . PART : 2 Er . Ramprasad Kumawat ( M.Tech .)

2. Airport Engineering Introduction: Requirements to Airport Planning, Airport Classifications, Factors in Airport Site Selection, Airport Size. Planning of Airport: Requirements of Airport- Terminal Area, Runway Length etc.

3. Factors in Airport Site Selection Air traffic potential Magnitude of passenger and freight traffic expected Adequate access Sufficient airspace Circling radius should be taken care Sufficient land Various facilities, terminal buildings, security systems Atmospheric and meteorological conditions Availability of land for expansion Availability of utilities

4. Development of surrounding area Ground accessibility Presence of other airports Regional plan Soil characteristics Surrounding obstructions Use of air port

5. Atmospheric and meteorological conditions Visibility Fog, smoke, haze Affected by wind Development of area (industrial) Causes reduction in frequency and hence in capacity handling Wind Direction and intensity Associated topographical features (hills, valley) Windward/leeward side Locating development w.r.t site of airport

6. Availability of land for expansion Future prediction of air traffic Land for parking vehicles, providing facilities Land cost at later stage Availability of land at later stage Availability of utilities Water, power etc., Sewerage, communication etc.

7. Development of surrounding area Residential or sensitive area Industrial development Height of development Zoning laws Noise pollution Movement of air pollution Birds and hits at engines

8. Economy of construction Alternate sites to be examined Availability of local construction material Terrain even or not Problematic areas Water logging areas Reclaimed areas

9. Ground accessibility Travel time in air vs on ground Easily approachable using all modes Proximity to areas of trip generation Facilities for private vehicle users Efficient transport system

10. Presence of other airport Traffic volume circling radius Types of air crafts in different airports Type of operating facility Instrumental flight rules, design flight rules Separation distance between radii May cause Accidents, reduction in capacity

11. Characteristics of soil Strength of soil sub grade Drainage of soil Level of water table and its impact Sub-soil drainage effects Valley side may have flooding Soil with good amount of pervious material like sand or gravel is considered good

12. Use of airport Civil or for military Adaptability for other usage during emergencies Surrounding area obstructions Clear air space for take off and landing High rise buildings not allowed High trees are cleared off Zoning laws are made to take care

13. Size of Aircraft Defined by the space for operators, controlling systems, facilities, manpower etc. Controlled by peak aircraft traffic, aircraft characteristics Elevation of airport size above MSL density and air pressure reduces Effects runway requirements, lift, drag etc. Aircraft performance varies altitude, air density, pressure , temperature

14. Meteorological conditions Wind, temperature Effects runway orientation, length and no of runways reqd. Performance characteristics of aircraft Volume of air traffic (peak hour volume, size of aircraft, nature of air traffic, runways, taxiways etc.,)
