Owner oManual

This manual describes the operation and performance of the
1957 and 1958 Cessna Model 182, and the 1958 Cessna Sky-
lane. Equipment described as "Optional" denotes thatthe
subject equipment is optional on theModel 182. Much of this
equipment is standard on the 1958 Cessna Skylane. Except
for minor equipment changes, the 1957 and 1958 models are
identical structurally and operationally, and have the same
performance; therefore, this manual is applícable for both
years. The main difference between a1957 and 1958 model
is the rudder trim system which is installed on the 1958
model only. The 1957 model has a rudder trim tab which is
also described in this manual.
