JNTU B.Tech IV AIRPORT, RAILWAYS AND WATERWAYS Previous Question Paper (July/August - 2022 - R18)

The selection of an airport site is a critical process that requires balancing technical, economic, and environmental considerations. Key factors include:

• Regional Planning: The site must align with the master plan of the region, ensuring connectivity with existing transportation networks like highways and railways.
• Meteorological Conditions: Wind direction and speed are paramount. Runways must be oriented to minimize crosswinds, and the site should have minimal fog, haze, or low-visibility conditions.
• Topography and Soil: A relatively level site reduces earthwork costs. The soil must have high bearing capacity to support heavy aircraft loads and provide adequate drainage.
• Obstructions: The approach and takeoff paths must be free from tall buildings, towers, or hills to ensure safety and meet clearance standards.
• Environmental Impact: Noise pollution, air quality, and the impact on local wildlife and ecosystems must be evaluated to satisfy regulatory requirements.
• Accessibility: The site should be located within a reasonable distance of the city center to ensure convenience for passengers and efficient cargo transport.
• Future Expansion: Sufficient land must be available for future runway extensions and terminal capacity upgrades.

An airport layout is designed to facilitate the safe and efficient movement of aircraft, passengers, and cargo. The primary components include:

• Runway: The central paved strip where aircraft take off and land. Its orientation is determined by prevailing wind patterns.
• Taxiway: Paved paths connecting the runway to the apron, hangars, and terminals, allowing aircraft to move on the ground without obstructing the runway.
• Apron: A designated area where aircraft are parked, loaded, unloaded, refueled, or boarded. It is located adjacent to the terminal building.
• Terminal Building: The interface between ground and air transport. It handles passenger processing, including check-in, security screening, baggage claim, and customs.
• Hangar: Specialized structures used for the maintenance, repair, and storage of aircraft.
• Control Tower: The nerve center of the airport, housing air traffic controllers who manage aircraft movement on the ground and in the immediate airspace.
• Parking and Access Roads: Landside facilities that provide connectivity for private vehicles, public transport, and parking for passengers and staff.
