Piper WARRIOR III PA-28-161, Pilot Operating Handbook

Page: 141 / 190

The annunciator panel includes alternator inop., and oil pressure indicator
lights. The annunciator panel also includes a vacuum inop. light, low volts and
starter engage indicator lights. The annunciator panel lights are provided only
as a warning to the pilot that a system may not be operating properly, and that
he should check and monitor the applicable system gauge to determine when
or if any necessary action is required.
Electrical accessories include navigation lights, wing tip recognition lights,
wing tip strobe lights, landing light, instrument lighting, and cabin dome light.
Circuits will handle the addition of communications and navigational
equipment.
A flood light, mounted in the overhead panel, provides instrument and
cockpit lighting for night flying. The light is controlled by a rheostat switch
located adjacent to the light. A map light window in the lens is actuated by an
adjacent switch.
WARNING
Anti-collision lights should not be operating
when flying through cloud, fog or haze, since the
reflected light can produce spatial dis-
orientation. Strobe lights should not be used in
close proximity to the ground such as during
taxiing, takeoff or landing.
Unlike previous generator systems, the ammeter as installed does not show
battery discharge; rather, it indicates the electrical load on the alternator in
amperes. With all the electrical equipment off and the master switch on, the
ammeter will indicate the charging rate of the battery. As each electrical unit
is switched on, the ammeter will indicate the total ampere draw of all the
units including the battery. For example, the average continuous load for
night flight with radios on is about 30 amperes. This 30 ampere value plus
approximately 2 amperes for a fully charged battery will appear continuously
under these flight conditions. The amount of current shown on the ammeter
will tell immediately if the alternator system is operating normally, as the
amount of current shown should equal the total amperage drawn by the
electrical equipment which is operating.
For abnormal and/or emergency operation and procedures, see Section
3.
