the final heat exchanger forward of the firewall. This is the same
system that provides cabin pressurization, and heat is generated by the
compression of the outside air by the turbochargers (there is no muffler
heat shroud). Maximum heat is provided when the CABIN TEMP
control is pulled out to the PULL HOT position. The airflow is
diverted to the defroster vents mounted below the windshield when the
CABIN AIR control is pulled out to the DEFROST position.
When the CABIN TEMP control is pushed fully in, the turbocharger
bleed air is routed through a third intercooler. Even though this will
decrease the temperature of the air, it may still be necessary to engage
the air conditioner to reduce the cabin temperature. The air conditioner
does not bring fresh air into the cabin; it cools and recirculates the
existing environment.
PITOT PRESSURE SYSTEM
A standard heated pitot probe is located on the lower, outboard side of
the left wing. If flights have the potential of below freezing
temperatures, IMC conditions, or precipitation, a check of the pitot
heater must be made prior to flight.
This check can be made during preflight by turning the master switch
on, the pitot heater power on for a few seconds (less than 10 typically)
and then feeling the probe for warmth. The preflight must also check
that the probe opening has not become home for a wasp and that any
cover has been removed.
NOTE
Probe heater power should never be left on except
in flight. Overheating and loss of the element will
occur.
STATIC PRESSURE SYSTEM
The static ports are located on the left and right sides of the fuselage
near the baggage door. If the aircraft has been outdoors for some time
the preflight should check for cleanliness. There is a static system
drain beneath the baggage floor and if the plane has been exposed to
rain the drain should be checked to preclude water in the system which
will introduce error into the altimeter, VSI, and airspeed system.
Since this is a pressurized aircraft, there is no alternate static system.
Attempting to recover from a static system blockage by opening the
static system to the cabin will produce erroneous readings unless the
cabin is completely depressurized.
