pulled out to disconnect the circuit. If a surge or over-loading amperage is
placed on a CBS switch, the built-in circuit breaker will open turning the switch
off, thus protecting the circuit. After reducing the electrical load, turn the switch
back to the ON position to reset the CBS breaker.

LIGHTING SYSTEM

Internal cockpit flood lighting is controlled by a CBS on the overhead panel.
Conventional anti-collision, position and safety strobe lights are located on each
wingtip. These lights are encased in a clear-plastic, flush-mounted cover for
protection and decreased drag. The center overhead panel has an ON/OFF
circuit breaker-switch (CBS) for the strobe lights.
The landing light is located in the leading edge of the left wing.
PITOT-STATIC SYSTEM AND INTRUMENTS
The pitot tube consists of a ram air duct located inside a cylindrical air chamber.
The ram air is received from a tube positioned ahead of the left wing. The tube
supplies ram air pressure to the airspeed indicator. The static ports are located
on both sides of the aft fuselage and supply outside atmospheric pressure to the
airspeed indicator, altimeter, mode C, and vertical speed indicator.

AIRSPEED INDICATOR

The airspeed indicator (ASI) is the instrument that displays how fast the aircraft is
traveling, in knots, through the air. Ram air pressure and static atmospheric
pressure supplied by the pitot tube are compared by a diaphragm that expands
and contracts as the difference between the two varies. Linkages are connected
between the diaphragm and the indicator needle gives the pilot a visual reading
of the indicated airspeed at any given time.

ALTIMETER

The altimeter (ALT) contains aneroid wafers that expand and contract as
atmospheric pressure changes. As altitude increases, the atmospheric pressure
decreases, and the aneroid wafers expand. As altitude decreases, the aneroid
wafers will contract. Atmospheric pressure is supplied to the altimeter by the
static ports on both sides of the aft fuselage. Mechanical linkages attached to
the aneroid wafers move the needles on the altimeter face. A knob on the
altimeter‟s face allows the pilot to enter the correct barometric pressure into the
Kollsman window.
