2. Regulating Authority
âą ICAO- International Civil Aviation Organization,
an agency of UN headquartered at Montreal
Canada
It develops standards and laws for
international flights
âą FAA- Federal Aviation Agency, a governmental
body of US headquartered Washington DC
âą AAI & DGCA- Airport Authority of India &
Directorate General of Civil Aviation

3. Airport Authority of India
âą Controls overall air navigation in India
âą Came into being on 1st April, 1995 and is
headquartered at New Delhi
âą Formed by merging NAA (National Airport
Authority) and IAAI (International Airport
Authority of India)
âą Functions of AAI
â Control and management of the Indian airspace
extending beyond the territory limits
â Design, development and operation of domestic
and international airports
â Construction and management of facilities

4. âą Factors to be considered for airport site
selection:-
ïTopography (less obstruction i.e proper zoning
laws, better visibility)
ïAnalysis for wind from wind rose diagram
ïGrade, drainage & soil characteristics
ïAvailability of utilities (water supply,
electricity)
ïEconomic consideration

5. RUNWAY CONFIGURATION
âą FAA includes over 20 runway layouts
âą Amongst them there are 4 basic runway
patterns :
1. SIMPLE RUNWAY
2. PARALLEL RUNWAY
3. OPEN-V RUNWAYS
4. INTERSECTING RUNWAYS
Parking system for runway
5
8. OPEN-V RUNWAYS
Runways diverging from different directions but do not
intersect and form an open-V shape are âOPEN-V runwaysâ
8
9. INTERSECTING RUNWAYS
Two or more runways that cross each other are classified as
intersecting runways.
This type of runway is used when there are relatively strong
prevailing winds from more than one direction during the
year.

10. RUNWAY LIGHTING
âą These lights are used to assist pilot in to
identify the runway
âą GREEN THRESHOLD LIGHTS : Line the
runway edge
âą RED LIGHTS : Mark the end of runway
âą BLUE LIGHTS : Run alongside taxiways
âą While runways have YELLOW or WHITE
lights marking their edges

16. Aircraft characteristics
âą Type of propulsion engine
âą Size of aircraft
âą Minimum turning radius
âą Capacity of aircraft
âą Aircraft weight and wheel configuration
âą Jet blast
âą noise
16
17. weight &wheel configuration
âą Different types of weights
â Operating empty weight
âą Constant weight except payload and fuel =w1
â Pay load
âą Load for which revenues are generated (passengers + freight)
â Zero-fuel weight
âą W1 + payload=w2
â Maximum take-off weight
âą Total amount of weight when it is taking off from runway,
w3=w2+fuel
â Maximum standard landing weight
âą Fuel consumed during transport will be deducted from take-off
weight i.e < w3
17
18. Classification of Airports
âą Based on
ïBasic runway length- A(2100m), B, C, D,
E(600m)
ïTyre pressure- 1(8.5kg/cm2), 2, 3, 4, 5, 6,
7(2.5kg/cm2)
18
19. Factors affecting the size of airport
â Defined by the space for operators, controlling systems,
facilities, manpower etc.
â Controlled by peak aircraft traffic, aircraft characteristics
â Elevation of airport size above MSL
âą density and air pressure reduces
âą Effects runway requirements, lift, drag etc.
âą Aircraft performance varies altitude, air density, pressure ,
temperature
â Meteorological conditions
âą Wind, temperature
âą Effects runway orientation, length and no of runways reqd.
â Performance characteristics of aircraft
â Volume of air traffic (peak hour volume, size of aircraft, nature
of air traffic, runways, taxiways etc.,)
19
25. WIND ROSE ANALYSIS
âą An approach often used in determining
the runway orientation
âą The method uses a wind rose template
âą A transparent runway template is placed
and rotated around the center of wind
rose
âą At each rotating angle, the percentage of
allowable cross winds is measured
25
27. Basic Runway Length
Assumed standard conditions
âą Airport altitude is at sea level
âą Temperature at airport is 15 degree Celsius
(standard temperature at any location is 15-
0.0065*elevation in metres )
âą Runway is levelled in longitudinal direction
âą No wind is blowing on runway
âą Aircraft is loaded to its full loading capacity
27
28. Basic Runway Length
Determined by considering following 3 cases:-
âą Normal landing case
âą Normal take-off case
âą Engine failure case
The case which works out the highest value for
length is finally adopted

41. Q- calculate for the turning radius of taxiway for
an supersonic aircraft having wheel base=17.7m,
width of taxiway 22.5m, wheel tread=6.62m,
turning velocity=40kmph and f=0.13
Ans-180m
