9.4.7.7 EGT
EGT is shown on the first four bar graph columns. These
are labeled 1 through 4 above the columns. The lower
limit of the graph range represents half of the allowable
range and the top of the range represents the maximum
temperature. When there is a dot under one of the
cylinder numbers above the column, the appropriate
numerical value of the EGT is shown on the left side of
the digital display cylinder. In the example above, the
EGT for cylinder 4 is 1340°F.
9.4.7.8 CHT
The CHT is represented by a missing segment in the bar
graph column. The scale is shown on the left side of the
bezel. The numerical value of the CHT is shown on the
right side of the digital display for each cylinder when
there is a dot under one of the cylinder numbers above
the column. In the example above, the CHT in cylinder 4
is 376°F.
9.4.7.9 LeanFind
JPI's EDM-800 provides two methods of leaning: lean
rich of peak (LEAN R) or lean of peak (LEAN L) (in other
words, leaning past peak EGT). Lycoming does not
recommend operations lean of peak.
