FUEL FUEL LO TEMP
Applicable to:
L2 This caution appears, as soon as the inner tank temperature is less than -37 °C, or outer or trim
tank temperature is less than -40 °C. However, at this threshold: Crew action is required for JET A
FUEL only, and no crew action is required for other fuel types.
For all other fuel types: This caution will automatically be recalled, if the temperature reaches
-44 °C (inner tank temp), or -47 °C (outer or trim tank temp).
Regardless of the fuel type, the flight crew may consider delaying application of the rest of
procedure, until reaching the minimum fuel temperature specific to their fuel type Refer to LIM-28
FUEL TEMPERATURE.
