plz explain about air ways?
Answers
An airway or air route is a defined corridor that connects one specified location to another at a specified altitude, along which an aircraft that meets the requirements of the airway may be flown.[1][2][3][4] Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellite navigation systems, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids.
Advantages
I. High Speed:
Air transport is the fastest mode of transport and therefore suitable carriage of goods over a long distance requiring less time. There is no substitute for air transport when the transport of goods is required urgently.
II. Quick Service:
Air transport provides comfortable, efficient and quick transport service. It is regarded as best mode of transport for transporting perishable goods.
III. No Infrastructure Investment:
Air transport does not give emphasis on construction of tracks like railways. As no capital investment in surface track is needed, it is a less costly mode of transport.
IV. Easy Access:
Air transport is regarded as the only means of transport in those areas which are not easily accessible to other modes of transport. It is therefore accessible to all areas regardless the obstruction of land.
V. No Physical Barrier:
Air transport is free from physical barriers because it follows the shortest and direct routes where seas, mountains and forests do not obstruct.
VI. Natural Route:
Aircrafts travels to any place without any natural obstacles or barriers. Because the custom formalities are compiled very quickly. It avoids delay in obtaining clearance.
VII. National Defence:
It plays a significant role in the national defense of the country because modern wars are conducted with the help of aero planes. Airways has a upper hand a destroying the enemy in a short period.
Disadvantages
I. Risky:
Air transport is the most risky form of transport because a minor accident may put a substantial loss to the goods, passengers and the crew. The chances of accidents are greater in comparison to other modes of transport.
II. Very Costly:
Air transport is regarded as the costliest mode of transport. The operating cost of aero-planes are higher and it involves a great deal of expenditure on the construction of aerodromes and aircraft. Because of this reason the fare of air transport are so high that it becomes beyond the reach the common people.
III. Small Carrying Capacity:
The aircrafts have small carrying capacity and therefore these are not suitable for carrying bulky and cheaper goods. the load capacity cannot be increased as it is found in case of rails.
IV. Unreliable:
Most of the air transport are uncertain and the unreliable because these are controlled by weather condition. It is seriously affected by adverse weather conditions. Fog, snow and heavy rain weather may cause cancellation of some flights.
V. Huge Investment:
Air transport requires huge investment for construction and maintenance of aerodromes. It also requires trained, experienced and skilled personnel which involves a substantial investment.
