optimizing
your
glide
angle.
However,
many
more
experienced
glider
pilots
consider
it
to
be
less
safe
than
leaving
the
MacCready
number
at
a
setting
that
matches
the
actual
soaring
lift
conditions.
The
reason
is
that
at
a
MacCready
setting
of
zero
you
are
at
the
ragged
edge
of
making
it
home.
You
have
no
margin
for
error
(or
sink).
You
can’t
slow
down
any
additional
amount
to
stretch
your
glide
or
speed
up
to
get
through
sink.
With
the
MacCready
set
to
match
the
day’s
soaring
conditions
the
flight
computer
will
recommend
that
you
have
more
altitude
before
starting
your
final
glide
which
will
allow
you
to
slow
down
to
stretch
your
glide
in
the
future
if
necessary
or
speed
up
in
sink
and
still
have
enough
extra
altitude
to
make
it
home.
In
addition,
you
will
arrive
home
more
quickly.
Total
Energy
Final
Glide
The
ClearNav
uses
a
feature
called
“Total
Energy
Final
Glide”
to
take
airspeed
into
account
when
calculating
glide
altitudes.
When
your
speed
increases
the
number
in
the
Final
Glide
window
will
decrease
because
less
altitude
is
required
to
make
it
to
your
destination
–
because
you
can
pull
up
and
gain
some
altitude
at
any
time.
When
your
speed
decreases
the
number
in
the
Final
Glide
window
will
increase
because
more
altitude
is
required
to
make
it
to
your
destination
–
because
you
have
less
extra
energy
to
convert
into
altitude.
