SECTION 3 • EMERGENCY PROCEDURES
WARNING
The malfunction of any required deice equip-
ment requires immediate action to exit icing
conditions. Depending on the severity of the
icing encounter, failure to take immediate
positive action can lead to performance losses
severe enough to make level flight impossible.
Therefore, upon verification of a system mal-
function or failure, climb or descend out of
icing conditions if this provides the shortest
route. If exit must be made in level flight,
consider the use of maximum power and exit
by the most direct route. The effect of the
additional fuel burned at higher power settings
on aircraft range must be considered and an
alternate airport chosen if necessary.
ALTERNATOR FAILURE IN ICING CONDITIONS (ALTERNATOR
annunciator light illuminated)
Verify failure ........................................................................ observe runmeter for
both alternators
Electrical loads .................................................................. reduce below 60 amps
AN (volt/ammeter) switch ................................................ cycle while observing
ALTNTR circuit breaker
ammeter to determine
affected alternator
(affected alternator) .............................................................................. check
ALTNTR switch (affected alternator) ................................... OFF (for 1 second),
then ON
If unable to restore alternator:
AL'IN'I'R. switch (affected altemator) ............................................................ OFF
Either alternator will supply sufficient current for all required deice
equipment and avionics. Other equipment may be turned on but in no case may
the total load exceed 60 amps. The cabin recycle blowers and the strobe
position and landing lights draw considerable current and should be turned
off unless required. Immediate action should be taken to exit icing con-
ditions.
