In aviation, communication is a basic necessity of which it
thrives upon. Therefore, I’m focusing on a few systems onboard an aircraft,
that are vital to the safety and efficiency the airline industry is renowned
With the ever-growing number of
aircraft in the skies today, radio communication between them and controllers
on the ground has become more significant than ever. As a result, VHF and HF
transceivers are fitted onboard aircraft so that pilots may receive and
readback instructions to ensure safety and separation throughout the flight.
These transceivers consist of a radio
transmitter and receiver which work on frequencies that reach farther than the
average local radio station,92.7Hz, as supposed to: 118–136.975MHz.
In addition, communication between
personnel on the aircraft is of equal importance. Therefore, modern commercial
jets are also fitted with an intercom system that allows cabin crew to converse
discreetly between them, without the need of also informing the passengers.
Which, if a problem arises, may cause fear and discomfort.
As well as this, most aircraft are
fitted with a
second intercom which when on the ground, allows ground crew along with
mechanics, to communicate with pilots
and each other from different areas of the
plane. Each have to connect to the aircraft using sockets just like ones on
your phone; but bigger.
Communication in aviation, sprouts
into a vast spectrum of technology and signals. However, most dismal of all are
the cockpit voice recorder and flight data recorder. Which are hidden at the
rear of the aircraft, in case of disaster.
These two boxes record the final few minutes of the pilots’ voices as well as
the aircraft’s position, speed, altitude etc. The purpose to be able to
retrieve the data and trace the events leading up to the crash, in hope to
avoid the same mistakes in the future.
Designed to survive the crash and be
found, these boxes are built to withstand anything; from fires to, deep ocean
depths. Therefore, they are heavily reinforced and equipped with locating beacons
to aid search and rescue operations. Which, when all else fails: shows how
vital communication in aviation really is.
