Airport Engineering - Planning

Airport Planning:
Airport Engineering

1. Planning:

  • The regional plan usually provides the following info:
1. Approximate locations of airport in National Map.
2. Classification of Airport.
3. Location of Air Strip.
4. Routes of Air Travel.
  • Following Data is collected for Regional Planning:
1. Population.
2.Topographical and Geographical features.
3. Existing Airport in Vicinity.
4. Air traffic Characteristics
  • Minimum Spacing from Existing Airport:
1. For Airport serving small general aviation aircrafts under VFR conditions = 3.2 km 
2. For Airport serving bigger aircraft under VFR conditions = 6.4 km
3. For Airport operating piston engine aircraft under IFR conditions = 25.6 km
4.For jet aircrafts under IFR conditions = 160 km
The best location is site adjacent to the main highway.

2. Approach Zone:

  • The width clearance area are known as approach zone, required on either side of runway along the direction of landing and take off.
  • Over this area the aircraft can safely loose or gain altitude.

3. Clear Zone:

  • It is the inner most portion of approach zone and the most critical position from obstruction view point.

4. Turning Zone:

  • During the take off of the engine fails or pilot select to land in case of an emergency then aircraft will have to take a turn and come in line with runway before landing.
  • The area of airport other than the approach area, which is used for turning operation is known as turning zone.

Timber Buildings !?

Timber Buildings !?  Why do we need a timber building? Yes, timber buildings. As on earth human population is on an exponential rise, many and many people are trying to get home in a city where they have easy excess for the workplace for their own living. In the near future, as the population gets more concentrated in cities more and more structures I mean Tall Structures need to be built. Loading Bearing and Comparison So now architects and builders have opted for old Technic of using timber as a building material eliminating concrete and steel. Yes, it is very hard to find this amount of trees but not impossible. It can be grown and regrown as needed. Many projects have been in progress of this idea and it reduces about 75% of carbon emission as compared to concrete and steel structure. Using timber coming directly from the forest doesn't have the appropriate strength required for a high rise building. So designers came up with the new idea of CLT
