2. An airplane or aeroplane (informally plane) is a powered, fixed-
wing aircraft that is propelled forward by thrust from a jet
engine orpropeller. Airplanes come in a variety of sizes,
shapes, and wing configurations. The broad spectrum of uses
for airplanes includesrecreation, transportation of goods and
people, military, and research. Commercial aviation is a
massive industry involving the flying of tens of thousands of
passengers daily on airliners. Most airplanes are flown by
a pilot on board the aircraft, but some are designed to
be remotely or computer-controlled.
3. 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.
4. 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.
5. 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.
6. IV. 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.
V. 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.
