Section III. INSTRUMENT FLIGHT
This aircraft is qualified for operation under
instrument flight meteorological conditions. Handling
characteristics, stability characteristics, and range are
the same during instrument flight conditions as when
under visual flight conditions.

Section IV. FLIGHT CHARACTERISTICS
A warning in the form of light buffeting may be
felt when approaching a stall. An aural warning is
provided by the warning horn. The warning horn will
begin to sound approximately 5 to 19 knots above power
off stall speed, depending on aircraft configuration,
altitude, and power. If correct stall recovery technique is
used, very little altitude will be lost during the stall
recovery. For the purpose of this section, the term
power on means that both engines and propellers of the
aircraft are operating normally and are responsive to
pilot control. The term power off means that both
engines are operating at idle power. During practice,
enter power off stalls from normal glides. Enter power
on stalls by smoothly increasing pitch attitude to a climb
attitude obviously impossible for the aircraft to maintain,
and hold that attitude until the stall occurs.
Power On Stalls. The power on stall attitude is
very steep and, unless this high pitch attitude is
maintained, the aircraft will generally settle or mush
instead of stall. It is difficult to stall the aircraft
inadvertently in any normal maneuver. A light buffet
precedes the stall, and the first indication of approaching
stall is generally a decrease in control effectiveness,
accompanied by a tone from the stall warning horn. The
stall itself is characterized by a rolling tendency if the
aircraft is allowed to yaw. The proper use of rudder will
minimize the tendency to roll. A slight pitching tendency
will develop if the aircraft is held in the stall, resulting in
the nose dropping slightly, then pitching up toward the
horizon; this cycle is repeated until recovery is made.
Control is regained very quickly with little altitude loss,
providing the nose is not lowered excessively. Begin
recovery with forward movement of the control wheel
and a gradual return to level flight. The roll tendency
caused by yaw is more pronounced in power on stalls,
as is the pitching tendency.
Power Off Stalls. The roll tendency is
considerably less pronounced in power off stalls (in any
configuration), and is more easily prevented or corrected
by adequate rudder and aileron control, respectively.
The nose will generally drop straight through with some
tendency to pitch up again if recovery is not made
immediately. The Stall Speed graph (fig. 8-2) shows the
indicated power off stall speeds with aircraft in various
configurations. Altitude loss during a full stall may be as
high as 1270 feet P or 1107 feet Q.
Accelerated Stalls. The aircraft gives noticeable
stall warning in the form of buffeting when an
accelerated stall occurs. The stall warning horn and
buffet can be demonstrated in turns by applying
excessive back pressure on the control wheel.
