All powerplant and exterior lighting switches are grouped in a overhead
switch panel, with all avionics switches grouped in a switch panel just above
the throttle quadrant (figure 7-15). The circuit breaker panel is located on the
lower right side of the instrument panel (figure 7-15). Each breaker is clearly
marked to show which circuit it protects. Also, circuit provisions are made to
handle the addition of communications and navigational equipment.
Standard electrical accessories include the starter, the electric fuel
pump, electric engine primer, the stall warning horn, the ammeter, and the
annunciator panel.
The annunciator panel includes, alternator inop, oil pressure, vacuum
inop., low bus voltage, start engage, pitot heat and provisions for optional
air conditioner door open. The annunciator panel lights are provided only
as a warning to the pilot that a system may not be operating properly, and
that the applicable system gauge should be checked and monitored to
determine when or if any corrective action is required.
Standard electrical accessories include the navigation lights, anti
collision strobe lights, landing/taxi lights, instrument panel lighting and
cabin dome light.
Two lights, mounted in the overhead panel, provide instrument and cockpit
lighting for night flying. The lights are controlled by rheostat switches located
in the overhead panel. A map light window in each lens is actuated by an
adjacent switch. A wing tip landing/taxi light system consists of 2 lights (one in
each wing tip) and is operated by a rocker type switch mounted on the overhead
switch panel. (Wing tip lights also used as recognition lights.)
The digital ammeter in the alternator system displays in amperes the load
placed on the alternator. It does not indicate battery discharge. With all
electrical equipment off (except the master switch) the ammeter will be
indicating the amount of charging current demanded by the battery. As each
item of electrical equipment is turned on, the current will increase to a total
appearing on the ammeter. This total includes the battery. The average
continuous load for night flight, with radios on, is about 32 amperes. This 32
ampere value, plus approximately 2 amperes for a fully charged battery, will
appear continuously under these flight conditions.
WARNING Anti-collision lights should not be
operating when flying through cloud, fog or haze, since
the reflected light can produce spatial disorientation.
Strobe lights should not be used in close proximity to
the ground such as during taxiing, takeoff or landing.
