· Engine FUEL INLET TEMP high (³121°C).
· Engine FUEL NOZ TEMP high (³177°C).
· FEED TANK TEMP high.
WoffW: ³ 60°C for 10 min or >65°C for 15 sec
WonW: ³ 80°C for 15 sec (<5,000 lb fuel)
³ 60°C for 10 min or >65°C for 15 sec
(>5,000 lb fuel)
If a FUEL HOT caution is set, the parameter
which triggered the caution should be highlighted in
red on the ENG format.
At normal ambient conditions, the fuel system
should provide adequate cooling for the FADECs
and subsystem accessories. With extremely hot ambient
conditions (> 103°F), fuel system temperatures
can approach their limits, particularly during
extended low altitude flight or with low fuel states.
If a corresponding THERMAL caution has also
been set, the fuel thermal management system has
lost the capability to regulate fuel system temperatures.
In this case, increasing fuel flow may not
have the desired effect of reducing fuel system temperatures.
PRE-FLIGHT
1. Throttle affected engine - OFF
INFLIGHT
1 RDR knob - STBY (if practical)
Without a THERMAL caution -
2. Throttle affected engine - Increase fuel flow
above 3,500 pph.
3. Land as soon as practical.
With either THERMAL caution -
2. Throttle (THERMAL caution side) - OFF
3. Restart for landing.
POST-FLIGHT
1 RDR knob - OFF
If caution remains for more than 5 minutes-
2. Throttle (THERMAL caution side) - OFF

· The designated fuel/air heat exchanger is leaking,
and the fuel system has failed to shut off
flow to the heat exchanger.
Due to fuel/air heat exchanger location (above
the engine inlet), engine fuel ingestion is possible if
fuel flow is not immediately secured.
Failure to secure an engine with an unisolated fuel/
air heat exchanger leak may result in catastrophic
engine failure and/or fire.
*1. Throttle affected engine - OFF
*2. FIRE light affected engine - PUSH
3. Land as soon as possible.

· Fuel level in either feed tank is 1,125 lb.
· May also be an indication of a fuel transfer failure.
If a low level indication was caused by a transient
condition such as prolonged negative g flight, the
FUEL LO caution remains for 60 seconds after the
low level indication has cleared.
If the FUEL LO caution remains displayed, aircrew
must assume that at least one feed tank is below
1,125 lb regardless of displayed fuel quantity.
1. Throttles - Reduce fuel flow (if practical)
2. FUEL format - Check for fuel transfer failure
indications.
3. Land as soon as possible.

· Internal wing tank fuel asymmetry exceeds 350
lb.
· Tank 1 and 4 fuel is not scheduling properly
(e.g., tank 4 full and tank 1 empty).
Wing tank transfer failures are most likely the
result of a valve failure. If one internal wing tank
fails to transfer, the other is also commanded to
stop transferring shortly thereafter when wing tank
balancing logic detects a 200 lb split. When tank 4
drops to approximately 3,000 lb, the SDC declares a
wing transfer failure, cancels wing balancing logic,
and reinitiates transfer from the good tank. All fuel
from the failed tank should be available through
gravity transfer with the aid of bank angle changes
or a steady sideslip. Selecting INTR WING INHIBIT
isolates normal wing transfer/refuel and diverts
recirculation fuel to the feed tanks.
In general, only two types of tank 1 and 4 transfer
failures set the FUEL XFER caution (tank 4
