Climb - Piper Cherokee Six 300 Information Manual

CHEROKEE SIX - 3OO
CLIMB
The best rate of climb at gross weight will be obtained at 105 miles per hour. The best
angle of climb may be obtained at 95 miles per hour. At lighter than gross weight these speeds
are reduced somewhat.* For climbing en route, a speed of I l5 miles per hour is recommended.
This will produce better forward speed and increased visibility over the nose during the climb.
When reaching the desired altitude, the electric fuel pump may be turned off.
STALI,s
The stall characteristics of the Cherokee Six :ue conventional. Visual stall warning is
provided by a red light located on the left side of the instrument panel which illuminates
automatically between 5 and l0 miles per hour above the stall speed. The gross weight stalling
speed of the Cherokee Six with power off and full flaps is 63 miles per hour. With the flaps up
this speed is increased 8 miles per hour. Loss of altitude during stalls can be as great as 350 feet,
depending on configuration and power. The stall speed chart is at gross weight. Stallspeeds.at
lo,wer weights will be corespondingly less.
Stall speed in mph (Calibrated Airspeed):
Flaps Up
- 7l
Flaps Down - 63
CRI.IISING
The cruising speed of the Cherokee Six is determined by many factors, including power
setting, altitude, temperature,loading, and equipment installed on the airplane.
The normal maximum cruising power is 75% of the rated horsepower of the engine. True
airspeeds, which can be obtained at various altitudes and power settings, can be determined
from the Performance Charts Section.
When selecting cruising RPM below 2300, limiting manifold pressure for continuous
operation, as specified by the appropriate "Avco-Lycoming Operator's Manual," should be
observed.
To obtain the desired power, set the manifold pressure and RPM according to the power
setting table in this manual. After the desired power settings have been set up, adjust the
mixture control for corresponding best power setting as indicated by the fuel flow meter. The
low side of the power setting, as shown on the fuel flow meter, indicates best economy for that
percent of power while the high side indicated best power.
*To obtain the performance prcsented in the Performance Section of this manual, full power
(full throttle and 2700 RPM) must be used.
