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.,)
