BEST
CLIMBING
ANGLE.
The
velocity
is
now
still
less
by
reason
of
the
increased
angle
producing
increase
of
drift.
Less
velocity
at
a
given
angle
produces
less
lift,
but
the
increased
angle
more
or
less
offsets
the
loss
of
lift
due
to
the
decreased
velocity;
and,
in
addition,
the
thrust
is
now
hauling
the
aeroplane
upwards.
MAXIMUM
ANGLE.
The
greater
angle
has
now
produced
so
much
drift
as
to
lessen
the
velocity
to
a
point
where
the
combined
lifts
from
the
surface
and
from
the
thrust
are
only
just
able
to
maintain
horizontal
flight.
Any
greater
angle
will
result
in
a
still
lower
lift-drift
ratio.
The
lift
will
then
become
less
than
the
weight
and
the
aeroplane
will
consequently
fall.
Such
a
fall
is
known
as
"stalling"
or
"pancaking."
=NOTE.--The
golden
rule
for
beginners:
Never
exceed
the
Best
Climbing
Angle.
Always
maintain
the
flying
speed
of
the
aeroplane.=
