Taxiway Radius:

The radius for taxiway can be found by 
R = (V*V)/.f
R is radius of curve in m
V is the speed in kmph
f is the coefficient of friction

For airport serving large subsonic jet transports, minimum value of radius of curvature is 120 m whatever be the speed.
For airport serving supersonic transports, minimum radius must be 180 m.

Exit Taxiway:

Taxiway should be located such that landing aircraft leaves the runway as early as possible. Such taxiway is called Exit Taxiway.


Apron is paved area for aircraft parking, loading and unloading of passengers and cargo. This area is near terminal building or hangers. Size of apron depends upon number of gate positions. 

Holding Apron:

Waiting area for aircraft before take offs is called Holding Apron. It's size depends on peak hour aircraft movements, aircraft size and maneuvering characteristics.

Apron Turn Table:

It is used to expedite the parking of aircraft and save parking space.


Hanger is covered area for repair and servicing of the aircraft's. Number of Hangers depends on peak hour volume of aircraft's.


Fillets are provided at the junction or intersection of two or more number of traffic ways, such as runway, taxiway or apron.
ICAO recommends that the radius of the fillet should not be less than the width of the taxiway.

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
