Operations
Suggested setup:
•
Standard view
•
Automatic mode
Verify:
•
EGTs and CHTs consistent with past climbs. EGTs
should be in the 1100 to 1300°F range (100° to 300°F
cooler than cruise) due to fuel cooling.
Be alert for:
•
high EGT in one cylinder, 300°F above the others may
indicate plugged injector or leaking manifold gasket on
a carbureted engine. At high density altitude an overly
rich mixture can significantly reduce engine power.
•
If all EGT columns go off scale to the top of the
column, be sure you are not in Normalize view, as
indicated by the symbol NRM above the Scanner®
section. After the engine is warmed up, use LeanFind
to lean the mixture.
Cruise Suggested setup:
•
Normalize view
•
Automatic mode
Be alert for:
•
uneven EGTs (injected engines). Make fine
adjustments to throttle, then RPM, then mixture to level
the display columns.
•
abnormal patterns of EGTs and CHT. (see Engine
Diagnosis Chart on page 8).
Descent
Suggested setup:
•
Standard view
•
Manual mode
Be alert for:
CLD: shock cooling alarm is set to -60°F. Average cool rates of
-40°F/minute to -50°F/minute are normal, depending on the
engine size.
