Electrothermal Propeller Deice; Pitot Heat; Stall Warning Anti-Ice - Beechcraft Baron G58 Pilot Operating Handbook

Model G58
Ground use of windshield heat is limited to
10 minutes.

ELECTROTHERMAL PROPELLER DEICE

Propeller ice removal is accomplished by the electrically
heated deice boots bonded to each propeller blade. The sys-
tem uses the airplane's electrical power to heat portions of the
deice boots in a sequence controlled by a timer. The system is
controlled by an ON-OFF circuit breaker switch on the pilot's
subpanel. When the system is turned on, the ammeter will reg-
ister 14 to 18 amperes. The system can be operated continu-
ously in flight; it will function automatically until the switch is
turned off. Propeller imbalance can be relieved by varying
RPM. Increase RPM briefly, then return to the desired setting.
Repeat if necessary.
Do not operate the system with the engines
inoperative.

PITOT HEAT

A heating element is installed in the pitot mast. The heating
element is controlled by a switch located on the pilot's sub-
panel. The switch is placarded PITOT HEAT and should
remain off during ground operations, except for testing or for
short intervals of time to remove ice or snow from the mast.

STALL WARNING ANTI-ICE

The mounting pad and the stall warning vane are equipped
with heating elements that are activated anytime the switch on
the pilot's subpanel, placarded STALL WARN HEAT is turned
on.
