CLIMB
The
best
rate of climb
at
gross
weight will
be obtained
at
87 miles
per
hour.
The best
angle of climb
is at 76 miles
per
hour.
At lighter than
gross
weight, these
speeds are somewhat
reduced.
For
climbing
en route, a speed
of 100 miles
per
hour
is recommended.
This
will
produce
better
forward
speed and increased
visibility
over
the nose
during the
climb. Shallow
turns of
a few degrees
will also aid
forward
visibility during climb
out.
STALI"S
Stall characteristics
are conventional.
Audible stall
waming is
provided
by
a horn
located
behind the
instrument
panel
which sounds automatically
at
between
5 and l0
miles
per
hour
above stall
speed.
Stall speed
at a
gross
weight of 2325
pounds
witlt
power
off
and
full flaps
is 58 miles
per
hour.
With
flaps up,
this speed
is increased.
The
stall speed
chart
is at
