Cessna 182T 2001, Pilot Operating Handbook

Page: 106 / 254

SECTION 4 - NORMAL PROCEDURES CESSNA
FAA APPROVED MODEL 182T
For reduced noise levels, it is desirable to select the lowest RPM
in the green arc range for a given percent power that will provide
smooth engine operation. The cowl flaps should be opened, if
necessary, to maintain the cylinder head temperature at
approximately two-thirds of the normal operating range (green arc).
Figure 4-3. Cruise Performance Table
Cruise performance data in this handbook is based on a
recommended lean mixture setting which may be established using
the EGT indicator at powers of 80% MCP and lower as follows:
1. Lean the mixture slowly until the EGT peaks and begins to
drop.
2. Enrichen as needed to ensure operation at peak.
3. If engine operation is rough at peak EGT, further enrichen for
smooth operation.
LEANING WITH AN EGT INDICATOR
The exhaust gas temperature (EGT) may be used as an aid for
mixture leaning in cruising flight at 80% power or less. To adjust the
mixture, using this indicator, lean to establish the peak EGT as a
reference point, enrichen the mixture by the desired increment
based on Figure 4-4, EGT Table.
