NOTE: R-model 172s were originally delivered with
160-horsepower engines. However, ATP's R-model aircraft have
received a propeller modification that provides for an increase to
180 horsepower (matching the S model), which in turn increases
fuel burn and maximum allowable takeoff weight.
ATP's early-model Cessna 172s have different combinations of
engine horsepower and usable fuel. Some aircraft carry only
38 gallons of useable fuel, and have been modified with a
180-horsepower engine. These airplanes have an increased fuel
burn and a significantly reduced endurance of approximately 3
hours in the training environment – even with full tanks.
Calculate your fuel requirements carefully. Reference the
aircraft manuals and placards for the appropriate information.
Airworthiness and registration certificates, which list the aircraft model, can
be found on the forward lower left interior cabin wall. Weight and balance
information can be found in the blue aircraft maintenance logbook, as well as
Section 6 of the POH.
