Have
you
ever
seen
white
smoke/
fog
inside
your
aircraft?
Do
you
ever
wonder,
Oh
My
God
what
is
this?
Is
my
Plane
or
fire
or
is
there
any
technical
issue
going
on?
Are
you
curious
to
know
what
it
is
exactly?
Read
on!
Whether
you
have
noticed
it
or
not,
reading
about
it
will
prepare
you
for
the
next
time
if
you
see
fog
inside
your
aircraft
cabin,
you
need
not
worry
because
it’s
a
normal
process
that
is
carried
out
inside
an
aircraft
before
take-off.
In
this
article,
we
will
discuss
the
reasons
why
fogging
is
done
and
the
type
of
gas
that
is
used
in
the
process.
Why
is
fogging
done
inside
the
aircraft?
Do
you
know
the
maximum
altitude
at
which
there
is
enough
oxygen
in
the
atmosphere
to
support
human
breathing
is
around
20,000
feet
above
sea
level?
A
commercial
aircraft,
on
the
other
hand,
typically
flies
between
31,000
&
38,000
feet,
in
the
air,
and
reaches
its
flying
height
within
the
first
10
minutes
of
a
flight.
Hence
it
is
clear
that
humans
need
an
environment
where
they
can
breathe
normally
as
they
breathe
on
land
even
when
they
are
flying.
And
each
aircraft
has
a
specific
system
and
process
to
make
flying
smooth
for
everyone.
First
Reason:
With
the
above
explanation,
here
comes
our
first
reason
that
fogging
is
done
to
improve
the
air
quality
inside
the
cabin.
Air
in
aircraft
cabins
is
known
to
be
dry
and
low
in
humidity,
which
can
be
uncomfortable
for
both
passengers
and
crew.
To
make
the
air
more
comfortable
to
breathe,
fogging
works
to
enhance
the
humidity
inside
the
cabin
and
decrease
the
dryness.
Experts
say
that
the
unusual
“indoor
weather”
is
frequently
experienced
by
aircraft
taking
off
from
hot,
humid
locations.
That’s
because
the
aircraft’s
onboard
air
conditioning
system
is
quickly
cooling
and
condensing
the
humid
air
outside.
As
a
result,
waves
of
water
vapour
are
released
to
make
it
all
a
good
environment
to
breathe
and
travel
smoothly.
The
whole
process
may
often
be
called
Cabin
pressurization.
In
reality,
it
is
nothing
more
than
the
air
conditioner’s
extremely
cold
air
driving
moisture
out
of
the
air.
Although
most
aircraft
are
equipped
with
a
unique
water
separator
to
avoid
this
problem,
the
machinery
occasionally
fails
when
the
outside
temperature
and
humidity
are
particularly
high.

Second
Reason:
The
second
reason
that
the
fogging
is
done
inside
the
aircraft
before
take-off
is
to
clean
the
cabin
and
shield
the
crew
and
passengers
from
dangerous
microorganisms.
Fogging
is
the
process
of
covering
every
surface
in
the
cabin,
including
the
seats,
tray
tables,
overhead
bins,
and
lavatories,
with
a
fine
mist
of
disinfection.
By
eradicating
any
germs
or
viruses
that
might
be
in
the
cabin,
this
procedure
helps
to
lower
the
risk
of
infection.
This
practice
was
highly
in
use
during
the
covid
era,
Countries
have
different
regulations
regarding
whether
or
not
passengers
must
be
on
board
for
a
plane
to
be
disinfected,
though
most
demand
it
after
the
doors
are
shut.
Now
you
must
be
thinking
are
these
disinfectants
harmful
to
human
health?
So,
let
me
tell
you
that,
spraying
approved
permethrin-based
insecticides
does
not
provide
any
health
risks
to
passengers
or
crew,
according
to
the
WHO.
It
does,
however,
mention
that
after
being
introduced
to
pesticides
on
airplanes,
some
travellers
worry
about
their
health.
In
order
to
allay
passenger
concerns,
WHO
has
discovered
no
proof
that
the
listed
pesticide
sprays
are
harmful
to
human
health
if
used
as
advised.
Third
Reason:
The
third
reason
could
be
to
get
rid
of
any
odours
that
might
be
in
the
cabin.
For
long-haul
flights,
where
passengers
may
spend
many
hours
in
the
cabin,
this
is
especially
crucial.
The
disinfectant
used
in
fogging
helps
to
neutralize
any
unpleasant
odours,
creating
a
more
pleasant
environment
for
passengers
and
crew.
How
long
does
the
fog
stay
inside
the
aircraft
and
is
there
anything
to
worry
about?
Concluding
this
article,
I
would
like
to
tell
you
all
that
there
is
nothing
to
worry
about
at
all
and
the
fog
remains
only
for
a
minute
or
two
for
whatever
reason
it
is
being
sprayed.
