2. SITE SELECTION OF AIRPORT:-
Basic Requirements:-
• Airport use.
• Proximity to other airports.
• Ground accessibility.
• Topography.
3. SITE SELECTION OF AIRPORT:-
• Visibility.
• Wind.
• Soil characteristics.
• Availability of utilities from town.
• Future development.
• Economic considerations.
4. AIRPORT SURVEY:-
The airport surveys can be grouped in the following six categories:-
i. Traffic Survey
ii. Meteorological Survey
iii. Soil survey or geotechnical survey
iv. Topographical survey
v. Material survey
vi. Drainage survey
5. AIRPORT OBSTRUCTION:-
• Obstructions are the objects and entities, which are present in the
path of aircraft or on the facilities provided for the aircraft that
causes problem to safe movement of aircraft
• Obstructions are divided into 2 types:-
a) Imaginary surfaces
b) Objects with actual heights
7. TYPES OF IMAGINARY SURFACES:-
A) Approach Surface:-
• Provided at the end of landing side of runway.
• Trapezoidal in shape.
• Diverging away with upgrade.
• Longitudinally centered on the extended center line of runway.
• Take off climb surface is also trapezoidal in shape.
B) Conical Surface:-
• Extends upwards and outwards from inner HS to a point which is at some height above the HS.
• Circular in shape.
8. C) Horizontal Surface:-
• Extends from upper edge of transition surface and ends at lower or inner circular edge of
conical surface.
• Height of outer Horizontal Surface extends from:-
150m to 9900m – for airports with length of runway between 900m to 1500m.
150m to 15000m – for airports with length of runway more than 1500m.
D) Transition Surface:-
• Trapezoidal in shape.
• Extends along the landing strip.
• Slopes upward and outward to the IHS(Inner Horizontal Surface).
9. OBJECTS WITH ACTUAL READINGS:-
• Any object which is located beyond a distance of 4.5km from the runway end is
considered as an obstruction if its height above 30m increases by more than 7.5m
for each additional 1.5km distance from the runway.
• When we reach 15km from runway end it should not exceed 75m.
• Any object which projects above the minimum approach flight altitude or whose
height exceeds 150m above the ground is also to be considered as an
obstruction.
10. ZONES:-
• Runway Clear Zone:-
a) Provided after runway end starting at 60m from the
end within approach area.
b) Length determined by approach surface attaining a
height of 30m.
c) It is independent on the rate at which approach surface
is going up.
11. TURNING ZONE:-
• It is used in case of emergencies for turning of aircraft.
• Any object which is located within a distance of 4.5km from the ARP is
considered as an obstruction if its height exceeds 51m above the ground the
establish ed airport elevation whichever is more.
• If the value exceeds 150m with in 15km it remains same.
12. ZONING LAWS:-
• Height Zoning:-
a) Given w.r.t. 4.5km distance from runway and further w.r.t. every 1.5km upto a distance of
15km from airport.
b) The area should remains with low profile of development.
• Land Use Zoning:-
a) Governs the type of developments which is taking palce at the adjoining areas of airport.
b) These are classified as:-
closely related like terminal buildings, parking.
Non-Aviation use like commercial, industrial, residential or recreational.
13. ZONING LAWS:-
• Following factors must be considered w.r.t. the zoning laws:-
Zoning Laws or legal rules should not hamper the somebody rights.
Nature of ordinance or law should have the qualities like not unreasonable, not
arbitrary, not compulsive.
Zoning map has to be provided.
