Stalls; Turbulent Air Operation - Piper ARCHER II Pilot Operating Handbook

PIPER AIRCRAFT CORPORATION SECTION 4
PA-28-181, ARCHER II NORMAL PROCEDURES
Tie downs can be secured to rings provided under each wing and to the
tail skid. The rudder is held in position by its connections to the nose wheel
steering and normally does not have to be secured.
4.37 STALLS"
The stall characteristics of the Archer I] are conventional. An approach-
ing stall is indicated by a stall warning horn which is activated between five
and ten knots above stall speed. Mild airframe buffeting and gentle pitching
may also precede the stall.
The gross weight stalling speed of the Archer II with power off and full
flaps is 49 KIAS. With the flaps up this speed is increased 6 KTS. Loss of
altitude during stalls varies from 100 to 350 feet, depending on configuration
and power.
NOTE
The stall warning system is inoperative with the
master switch OFF.
During preflight, the stall warning system should be checked by turning
the master switch ON, lifting the detector and checking to determine if the
horn is actuated. The master switch should be returned to the OFF position
after the check is complete.
4.39 TURBULENT AIR OPERATION
In keeping with good operating practice used in all aircraft, it is recom-
mended that when turbulent air is encountered or expected, the airspeed be
reduced to maneuvering speed to reduce the structural loads caused by gusts
and to allow for inadvertent speed build-ups which may occur as a result of
the turbulence or of distractions caused by the conditions. (See Subsection °
2.3)
