FUEL TEMPERATURE
Fuel freeze should not be confused with fuel ice caused by frozen water
particles, but with the formation of wax crystals suspended in the fuel, which
can accumulate below the freeze point. Fuel tank temperature should be
maintained at least 3°C above the freezing point of the fuel being used (see
Section 1).
Maintaining a minimum fuel temperature should not be a concern unless the fuel
temperature lowers to within a few degrees of that limit. The rate of cooling of
the fuel at this point can be expected to be 3°C / hour with a maximum of
12°C / hour possible under the most extreme cold-day conditions.
Fuel temperature will tend to change toward total air temperature. If the total
air temperature is lower, it may be increased to raise the fuel temperature.
Total air temperature can be raised by:
· Deviating to a warmer air mass.
· Increasing mach number.
It may take up to an hour to stabilize the fuel temperature. In most cases, the
required descent would be within 3,000 to 5,000 feet below optimum altitude.
In the more severe cases, a descent to altitudes of 25,000 feet to 30,000 feet
might be required. An increase of .01 mach will result in an increase of 0.5°C
to 0.7°C total air temperature.

TURBINE ENGINE MONITORING PROGRAM
Continental employs an in-flight engine condition monitoring procedure called
“T.E.M.P.” (Turbine Engine Monitoring Program). Engine data, gathered by
the crew and relayed by ACARS or individual forms, generates computerized
trend analysis of each individual engine’s condition and performance. With this
data, early engine deterioration can be detected and action taken to prevent
failure.
Each crew will send this information for each flight segment greater than one
hour, conditions permitting. The minimum is one message per flight number for
flights of over one hour.
T.E.M.P. reports should be relayed via ACARS. If ACARS is inoperative or
not installed, use the T.E.M.P. logbook provided on the flight deck.
> The ACARS format for relaying engine data is displayed in the ACARS
CDU by pressing the ENG key. A sequence of data entries will appear starting
with “Gross Weight.” It is essential that the crew enter all the data carefully and
accurately. A complete engine condition report is illustrated on the following
page.
>@BCD Engine Data Reports are transmitted automatically. No crew
action is required.
>@ If Maintenance requests an Engine Report from the crew, use the
following steps to select the ENGINE DATA REPORT: Press <ACARS
<INFLIGHT <ENGINE DATA. Touch AUTO to activate the MANUAL Engine Data
Report. Follow the prompts through the report.
Note: Allow both engines to stabilize at cruise thrust for at least 3 minutes
prior to initiating the recording sequence. The autothrottles should be
disengaged during the engine-recording period and engine anti-ice
switches should be OFF.
