PIPER AIRCRAFT CORPORATION
PA-28R-201, ARROW
4.25 CLIMB (4.5i)
SECTION 4
NORMAL PROCEDURES
On climb-out after takeoff,
it
is recommended that the best angle of
climb speed (78 KIAS)
~
maintained only if obstacle clearance is a
consideration. The best rate of climb speed (90 KIAS) should be maintained
with full power on the engine until adequate terrain clearance is obtained. At
lighter than gross weight these speeds are reduced somewhat. An en route
climb speed of \04 KIAS or higher is also recommended. This increased
climb speed provides better engine cooling, less engine wear, reduced fuel
consumption, lower cabin noise level, and better forward visibility.
When reaching the desired altitude, the electric fuel pump maybe turned
OFF.
To obtain the performance presented in the Performance Section of this
handbook, full power (full throttle and 2700 rpm) must be used.
4.27 CRUISE (4.5j)
Following level-off for cruise, the airplane should be trimmed.
The cruising speed of the Arrow is determined by many factors,
including power setting, altitude, temperature, loading and equipment
installed in the airplane.
The normal maximum cruising power is 75% of the rated horsepower of
the engine. When selecting cruising rpm below 2400, 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.
Use of the mixture control in cruising flight reduces fuel consumption
significantly, especially at higher altitudes. The mixture should be leaned
during cruising operation when 75% power or less is being used. Ifanydoubt
exists as to the amount of power being used, the mixture should be in the full
RICH position for all operations.
