OPERA TING TIPS
The following Operating Tips are -of particular value in the operation of the Cherokee
Arrow IT.
I. Learn
to trim for take-off so that only a very Hght back pressure on the wheel
is
required to lift the airplane off the ground.
2. On take-off, do not retract the gear prematurely. The airplane may settle and make
contact with the ground because of lack of flying speed, atmospheric conditions, or
rolling terrain.
3. The best speed for take-off is about 65 MPH under nonnal conditions. Trying to pull
the airplane off the ground at too low an airspeed decreases the controllability of the
airplane
in
event of engine failure.
4. Jn hjgh density areas where high traffic pattern speeds are necessary or when it is
advantageous to extend the gear, it is permissible to extend the landing gear at speeds
up to
150 MPH.
5. Flaps may be lowered at airspeeds up to 125 MPH. To reduce flap operating loads, it
is desirable to have the airplane at a slower speed before extending the flaps.
6. Before attempting to reset any circuit breaker, allow a two to f
i
ve minute cooHng off
period.
7. Always determine position of landing gear by checking the gear position lights.
8.
Remember that when the panel lights are on, the gear position lights are very dim.
9. Before starting the engine, check that all radio switches, light switches, and the pi tot
heat switch are in the off position so
as
not to create
an
overloaded condition when
the starter is engaged.
10. A hlgh fuel pressure indication on the fuel flow indicator is a possible sign of
restricted air bleed nozzles.
l 1. The overvoltage relay
is
provided to protect the electronics equipment from a
momentary overvoltage condition (approximately 16.5 volts and up), or a
catastrophic regulator failure.
In
the event of a momentary condition, the relay will
open and the ammeter: will indicate zero ougmt from the alternator. The relay
may
be reset by switching the "ALT" switch to "OFF" for approximately 1 second and
then retuming the "ALT" switch to "ON."
1f
after recycling the "ALT" switch the
condition persists, the flight may be continued on battery alone by reducing battery
load to minimum.
12. It should always be kept in ntind that the back-up gear extender system is intended to
lower the gear during the approach should the pilot forget. However, the pilot should
always lower the gear during normal operations by using the gear selector switch on
the instrument panel.
13. The
vacuum gauge is provided to monitor the pressure available to assure the correct
operating speed of the vacuum-driven gyroscopic flight instruments.
It
also monitors
the condition of the cornmom air filter by measuring the flow of air through the
filter.
