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 Lean Find to lean the mixture.
