The Aeroplane Speaks. Fifth Edition

"Then,
if
the
Pilot
is
green,
my
chance
will
come,"
said
the
Maximum
Angle
of
Incidence.
"For
if
the
Angle
is
increased
over
the
Best
Climbing
Angle,
the
Drift
will
rush
up;
and
the
Speed,
and
with
it
the
Lift,
will,
when
my
Angle
is
reached,
drop
to
a
point
when
the
latter
will
be
no
more
than
the
Weight.
The
Margin
of
Lift
will
have
entirely
disappeared,
and
there
we
shall
be,
staggering
along
at
my
tremendous
angle,
and
only
just
maintaining
horizontal
flight."
"And
then
with
luck
I'll
get
my
chance,"
said
the
Drift.
"If
he
is
a
bit
worse
than
green,
he'll
perhaps
still
further
increase
the
Angle.
Then
the
Drift,
largely
increasing,
the
Speed,
and
consequently
the
Lift,
will
become
still
less,
i.e.,
less
than
the
Weight,
and
then--what
price
pancakes.[3]
Eh?"
"Thank
you,"
from
Efficiency,
"that
was
all
most
informing.
And
now
will
you
tell
me,
please,
how
the
greatest
Speed
may
be
secured?"
"Certainly,
now
it's
my
turn,"
piped
the
Minimum
Angle
of
Incidence.
"By
means
of
the
Elevator,
the
Pilot
places
the
Aeroplane
at
my
small
Angle,
at
which
the
Lift
only
just
equals
the
Weight,
and,
also,
at
which
we
shall
make
greater
speed
with
no
more
Drift
than
before.
Then
we
get
our
greatest
Speed,
just
maintaining
horizontal
flight."
"Yes;
though
I'm
out
of
the
horizontal
and
thrusting
downwards,"
grumbled
the
Propeller,
"and
that's
not
efficient,
though
I
suppose
it's
the
best
we
can
do
until
that
Inventor
fellow
finds
his
Mechanics."
