The Aeroplane Speaks. Fifth Edition
·
H. Barber
35
"Much
ado
about
nothing,"
quotes
the
Aeroplane
learnedly.
"Compromise
or
not,
I'm
climbing
a
thousand
feet
a
minute.
Ask
the
Altimeter.
He'll
confirm
it."
And
so
indeed
it
was.
The
vacuum
box
of
the
Altimeter
was
steadily
expanding
under
the
decreased
pressure
of
the
rarefied
air,
and
by
means
of
its
little
levers
and
its
wonderful
chain
no
larger
than
a
hair
it
was
moving
the
needle
round
the
gauge
and
indicating
the
ascent
at
the
rate
of
a
thousand
feet
a
minute.
And
lo!
the
Aeroplane
has
almost
reached
the
clouds!
But
what's
this?
A
sudden
gust,
and
down
sinks
one
wing
and
up
goes
the
other.
"Oh,
my
Horizontal
Equivalent!"
despairingly
call
the
Planes;
"it's
eloping
with
the
Lift,
and
what
in
the
name
of
Gravity
will
happen?
Surely
there
was
enough
scandal
in
the
Factory
without
this,
too!"
For
the
lift
varies
with
the
horizontal
equivalent
of
the
planes,
so
that
if
the
aeroplane
tilts
sideways
beyond
a
certain
angle,
the
lift
becomes
less
than
the
weight
of
the
machine,
which
must
then
fall.
A
fall
in
such
a
position
is
known
as
a
"side-slip."
But
the
ever-watchful
Pilot
instantly
depresses
one
aileron,
elevating
the
other,
with
just
a
touch
of
the
rudder
to
keep
on
the
course,
and
the
Planes
welcome
back
their
precious
Lift
as
the
Aeroplane
flicks
back
to
its
normal
position.
"Bit
bumpy
here
under
these
clouds,"
is
all
the
Pilot
says
as
he
heads
for
a
gap
between
them,
and
the
next
minute
the
Aeroplane
shoots
up
into
a
new
world
of
space.
