Why Use an
Aircraft Ground
Power Unit?
Aviation
has become a
pretty big
industry all
around the
world. The more
and more
airplanes we
see, we start to
see more
emissions from
the fuel that is
being used to
run all these
airplanes.
The government
regulations have
changed the way
emissions are
handled.
Why
use an aircraft
ground power
unit?
Not
only does it
help out on
emissions but it
is also saving
the airline or
the pilot of a
civilian
aircraft money
on fuel costs.
The airlines
have urged the
ground crew
employees to use
aircraft ground
power units
versus using APU's (auxiliary
power unit) as
they consume jet
fuel
tremendously. Aircraft ground
power units are
efficient power
generators and
use diesel fuel
instead of
aviation fuel. That is one of
the reasons why
to use an aircraft
ground power
unit.
Why
use an aircraft
ground power
unit?
The
power that
starts the
engines of an
aircraft is 24V,
40A/h lead-acid
battery or from
an external 28V
direct current
source such as
an aircraft
ground power
unit. While the
plane has
landed, the
engines shut
down and the
ground power
unit takes over
to feed the
aircraft with
the power that
is needed. An APU is still
used 45 percent
of the time when
supplemental
power is needed.
Saving
millions of
dollars a year
to the airlines
involved or
thousands of
dollars to the
civilian pilot
is just another
reason why to
use an aircraft
ground power
unit.
The aircraft
ground power
unit will do the
same as an APU
to provide
electrical power
for lighting,
heating and
cooling while
the aircraft is
on the ground
but will save so
much money
running on
diesel fuel
versus running
on aviation
fuel.
Why use an
aircraft ground
power unit?
Another reason
would be to
reduce any noise
pollution. An
aircraft running
it's engines
sitting on the
ground is
astronomically
loud. Many
airports do not
even allow
aircraft to use
APU's because of
the noise that
is still
involved.
An aircraft
ground power
unit will be the
small vehicle or
trailer that is
seen near where
the aircraft
parks when
it lands. They
can be powered
by diesel fuel
and sometimes
they are all
electric units
that can be
powered off and
on from some
sort of
electrical grid.
There are
basically two
types of
electrical
aircraft ground
power units with
one being 28
volt DC current
and the other
one would be an
AC unit. An
aircraft ground
power unit is
recommended to
be used for both
the starting of
an aircraft and
servicing of the
aircraft.
Why
use an aircraft
ground power
unit?
When the engines
or even an APU
is started on an
aircraft, the
battery will
have an enormous
strain put on
it. An aircraft
ground power
unit will
eliminate this
problem as it is
now powering the
aircraft. If a
battery on an
aircraft is not
sufficiently
charged, the
starting of an
aircraft engine
may suffer
unnecessary wear
and tear and
sometimes even
become damaged.
These
are just a few
of the reasons
why to use an
aircraft ground
power unit
but a TEMCo

explain more of
the reasons.
