The
electric
fuel
pump
should
be
turned
off
momentarily
during
ground
check
to
make
sure
that
the
engine-driven
pump
is
operating.
The
electric
fuel
pump
should
be on
during
take-off
to
prevent
loss
of power
should
the
engine-driven
pump
fail.
The
engine
is
warm
enough
for
take-off
when
the
throttle
can
be
opened
without
the
engine
faltering.
Do
not
take
off
with
a
dead
battery
as
some
voltage
is
needed
to
excite
the
alternator.

The
take-off
technique
is
conventional
for
the
Cherokee.
The
tab
should
be
set
slightly
aft
of
neutral,
with
the
exact
setting
determined
by
the
loading
of
the
aircraft.
Allow
the
air-
plane
to
accelerate
to
50
to
60
MPH,
then
ease
back
on
the
whee
1
enough
to
let
the
airplane
fly
itself
off
the
ground.
Pre-
mature
raising
of
the
nose,
or
raising
it
to
an
excessive
angle
will
result
in
a
delayed
take-off.
After
take-off
let
the
aircraft
accelerate
to
the
desired
climb
speed
by
lowering
the
nose
slightly.
Take-offs
are
normally
made
with
flaps
up.
However,
for
short
field
take-offs,
and
for
take-offs
under
difficult
conditions
such
as
deep
grass
or on a
soft
surface,
distances
can
be
re-
duced
appreciably
by
lowering
flaps
to
25
o.
CLIMB
The
best
rate
of climb
at
gross
weight
will
be
obtained
at
85
MPH.
The
best
angle
of
climb
may
be
obtained
at
74
MPH.
