If dashes are not displayed on the FUEL quantity line on the
FMC PERF INIT page:
Do not use FMC speed and altitude information.
Use manually calculated gross weight and performance
information from the QRH.
Do not use minimum maneuver speed or buffet margin
information.
Use the Flap Maneuver Speed table in the Performance-
Inflight section.
Stick shaker, VMO/MMO and minimum flap retraction speed
displays are unaffected.
CAUTION: If the FMC is used for manual entry of gross
weight to calculate reference speeds or fuel
remaining at destination, the information will
not remain accurate.
FUEL TEMP LOW
Condition: Fuel temperature is approaching minimum.
When fuel temperature is approaching fuel temperature
limit (3 degrees C (5 degrees F) above the fuel freeze point
or - 45 degrees C (- 49 degrees F) whichever is higher):
Increase speed, change altitude and/or deviate to a
warmer air mass to achieve a TAT equal to or higher than
the fuel temperature limit.
TAT will increase approximately 0.5 to 0.7 degrees C for
each .01 Mach increase in speed. In extreme conditions,
it may be necessary to descend as low as FL250.
