Every time
you get inside an airplane you will be informed about safety rules in order to
have a safe flight, and just before takeoff, the flight attendant will ask
you to turn all the electronic devices including your cell phone. Many people
don’t know why they are asked to do so and if they asked why the answer will
be that cellphones can interfere with the airplane`s radio system which might
cause a disaster.
A lot of
people, including the flight attendants in the airplane, believe that cellphones
can really cause a huge problem to the airplane due to the radio frequency
emitted from them which can interfere with the aircraft frequencies. However,
some people will just keep using their phones and nothing will happen to the
airplane.
“The real
reason the ban of cell phones exist has nothing to do with flight safety. Cell
phone networks have a small risk of not work properly when a phone accesses
them from a high vantage point, and so federal communication regulators
prohibit the use of mobile phones from the air. Federal aviation regulators
enforce it because of the communication laws” (Egan, 2007).
The real
fact is that airplane companies like Boing and Airbus spend millions of
dollars to enhance the safety of their aircrafts, thus they made their
aircraft immune to foreign signals and they work in completely different
frequency ranges. In fact, some aircraft have a built-in micro cellular tower
which can allow the passengers to use their cellphones and make international
calls to their loved ones.
However,
people still need to pay attention and turn all their electronic devices off
during the low altitude portion of the flight which are take-off and landing.
They should also keep their devices in a secure place because the last thing
you want is to have a flying IPad in the cabin!
Now, a lot
of people say that phones should be banned because it's annoying for other
passengers. That's fine, that's a perfectly valid perspective; but it's not
valid to promote this perspective by making up bad science to claim the phones
are a danger to the aircraft.
