Bimal K Srivastava:
Welcome all to today's chat session. Today's topic is about
Aeroplanes, you are all welcome to ask questions related to
aeroplanes and aviation
Manu: hi sir
Bitto: good afternoon sir
Bimal Srivastava: Hello Manu, do you have any question?
Manu: Why do not plane take off vertically
Bimal Srivastava: Manu, for take off, Aeroplanes need high
lift and hence heavy engine power and for that aeroplanes had to
make a long run on the run way. For vertical take off with heavy
load, extraordinary power will be needed which is not possible in
present day design of aircraft engines.
Sachin: what is the basic principle behind the take off of
Bimal Srivastava: Sachin, Four forces namely lift, weight, thrust and drag
are needed for keeping an aeroplane in the air. Thrust is achieved
through engine power, Lift through engine power and design of
aeroplanes, Weight is the weight of the aeroplane and the Drag is
produced through the reactions of the air. For take off, lift should
be greater than weight and thrust should be greater than drag.
Thakur: what is a stealth plane, how do they hide a plane
Bimal Srivastava: Thakur, In a Stealth Plane the radar
waves are not allowed to get reflected by virtue of its design. That
is why stealth plane cannot be seen on radar, and therefore, cannot
be detected by enemies.
Gaurav: What happens if it rains on the day?
Bimal Srivastava: Gaurav, Modern aeroplanes are capable of
operating in bad weather conditions including rain. However, due to
rain the runway becomes slippery and visibility becomes poor. Thus
the pilot has to exercise caution while landing in rain.
Gao Shan: hello sir
india have any stealth planes
does not have any Stealth Planes. These are meant for defence
purposes, very expensive and still under test stage.
Gao Shan: can you tell me, What are those two red lights that
flashing on and off on top of bridges.
Bimal Srivastava: Gao Shan, They are called obstruction
lights and are meant to warn the pilot about a hazard.
Chotiwala: GE sir jii
Chotiwala: what is plan?
Chotiwala, The flight plan is filed by the
pilot to the air traffic control unit before starting the flight. It
shows its intended route and flight details.
Manu: how does air traffic controller control traffic in air?
Are there any predefined routes
Manu, The Air traffic controller remains in radio contact with the
pilot and passes instructions to the pilot to follow a particular
height and direction depending upon other traffic. Thus, he is able
to separate one aircraft from other and avoids collision between
various aeroplanes flying together. There are predefined routes all
over the world and pilots are required to follow those routes.
concept to develop a new plane?
Chotiwala, Aeronautical Engineers design new aeroplanes depending
upon various requirements such as the load requirements, speed,
capacity, fuel consumption, purpose of aircraft etc. They chose and
design the shape of the wings and other parts of the aircraft, use
special aircraft material, design suitable engines achieving the
dinesh: what is microlight flights
Dinesh, Microlight flights are very light aircraft with a small
manu: ok sir
Guru: differ between fighter plane and other plane.
Guru, The fighter planes are lighter in weight, can be manoeuvred
and turned swiftly; can go at a very high speed and climb and decend
at fast speed. They are also capable of attacking enemy aircraft and
Gao Shan: sir if the radio contact fails
Gao, there are special operational procedures designed for radio
failure. The pilot and the Air Traffic Control Unit can follow those
procedures in case of radio failure.
Gao Shan: aic to manu answers
Chotiwala: how developed the theory of fighter plane
Gao Shan: sir if the radio contact fails?
a/c to manu answers
Gao Shan: what r the alternative options
Gao, the air traffic controller will guide the aeroplane based on
radar image. He will ask other aircraft to clear the path of
aircraft having radio failure
Kaju munshi: Sir what are pioneer aeroplanes
Kaju Munshi, pioneer aeroplanes are the aeroplanes having some novel
technology and New features. For example Concorde, Airbus A-380 and
Boeing 787 are pioneer planes having new technology.
Chotiwala: name of new technology u used...?
Chotiwala, your question is not clear
Monika: sir what is FAA
Monika, FAA stands for Federal Aviation Administration. It is the
regulatory body for Civil Aviation in USA.
where can one get microlight flying licence
Bimal Srivastava: Manu, Please contact Director General of
Opposite Safdarjung Airport ,New Delhi 110003
Navneet kumar gupta:
good afternoon sir
Navneet kumar gupta: sir what is black box
Navneet, There are two black boxes installed in the aeroplane known
as Cockpit Voice Recorder(CVR) and Flight Data Recorder (FDR). They
record cockpit conversation and flight parameters during the flight.
Mostly used for accident investigation
Monika: what is AIAA
Monika, AIAA is not a standard aviation term .Please specify for the
sir jab hum upar ud jate hain to kaan kyon band ho jate hain
Bimal Srivastava: Monika, the atmospheric pressure at high
altitude is very low. Although the aeroplanes are pressurized, still
due to low air pressure we feel pain in ears.
Monika: what is Wind Tunnel Tests
Bimal Srivastava: Monika, In a wind tunnel, a model
aircraft is subjected through various tests to check the effect of
wind speed, lift, drag etc and effect of many other forces on
flights. Thus the capability of the actual aeroplane in flight is
Guru: sir why all aircraft have round and very small windows?
Bimal Srivastava: Guru, large windows would weaken the
aeroplane structure, and the aeroplane will not be able to
withstand the adverse atmospheric conditions at such high altitude.
Moreover when the aeroplane is flying at a height it needs air
conditioning and normal air pressure. The walls of aeroplane are
made very thick so that outside low pressure and temperature will
not adversely affect the passenger cabin.
Monika: ok sir thank u
Guru: please answer my question also sir
Is it possible to land or take off the plane through auto pilot.
Guru, Yes it is possible to fly, control and land the aeroplane
through auto pilot. However mostly, for landing the pilots prefer to
Navjyo: sir have u idea about Ace Air
Navjyo, please give me more details.
Navneet kumar gupta:
sir when aeroplane on the Runway what safety point apply in fog
Bimal Srivastava: Navneet, In fog the visibility becomes
low, and therefore assistance from ground landing facilities such as
radar and instrument landing system(ILS) etc is taken by the pilot.
Navjyo: Sir what r the careers opportunities for MCA in
Navjyo: how u start ur careers in this field
Bimal Srivastava: navjyo, Certain airlines need MCA for
their computer department. Please check the vacancy in the concerned
please give me
suggestion about my future
Bimal Srivastava: navjyo, Please go through the airlines
Navneet kumar gupta: barmuda angle is true or false
Wrold Cup 2007: hello sir jii
Jeetu: what type of fuel used in airplane
jeetu, Modern Jet aeroplanes use aviation kerosene,which is a type
of refined kerosene as fuel. Jeetu: is this fule better than
Bimal Srivastava: Jeetu, Aviation kerosene is cheaper than
petrol and it has got high potency to power the heavy jet aircraft .
World cup: sir, can
India win this world cup
Monika: bye bye sir
Jeetu: sir, why the fare of planes vary for same distance and
facilities, does cheaper planes are not good
World cup: what is ur fare to go West Indies
is this kerosene can be used in cars also, I mean is it available
Bimal Srivastava: No. Jeetu. Cars use piston engines, for
which petrol is required. Refined kerosene can be used only in Jet
Jeetu: please answer sir...
Bimal Srivastava: Jeetu, The fare is decided by the
airlines concerned and they do it depending upon the number of
passengers flying on the route, profitability of the route and many
other factors. Thus the fare varies from route to route.
hello kaju munshi
Jeetu: thanks sir
Jeetu: what type of material is used for construction of
Jeetu, Normally light and strong materials and alloys are used for
aircraft construction. Most common are Titanium, Aluminium, plastic
reinforced fibre, carbon fibre etc. Steel is used for engines.
Bimal Srivastava: Thank you for joining us in the chat
session. It was wonderful interacting with you. In
case you have any further query, you can send your questions to the
expert or at VP.
