FUEL LOW
Indications:
Fuel quantity displays yellow caution bars when fuel level decreases to 300
pounds; the red warning bar displays at 150 pounds. Low fuel warning
tick mark(s) displays at 127 to 97 LBS while in cruise flight.
NOTE
:
Under normal operating conditions (cruise flight), a low fuel warning tick mark
(left or right) will illuminate when approximately 127 to 97 total pounds remain
in the fuel tank. With tick mark(s) illuminated and both engines operating at MCP,
approximately 10 minutes of fuel remain.
Under conditions where either side of the fuel tank fails (i.e.,develops a
substantial leak) the system will display a low fuel warning tick mark when
approximately 10 minutes of fuel remain (65 LBS) on either side of the collector
tank at maximum OEI fuel consumption rate.
Procedures:
With low fuel warning tick mark(s) ON
140 KIAS MAXIMUM AND AVOID
UNCOORDINATED
TURNS/MANEUVERS
Indications:
Early display of low fuel warning tick marks - above 220 LBS in hover
and 160 LBS in cruise.
Conditions:
Fuel transfer system malfunction.
Procedures:
Place L BOOST and R BOOST switches OFF.
NOTE
:
Expect engine flameout on side with early low fuel warning tick mark illuminated.
FUEL BOOST PUMP FAILURE
Indications:
Alternating white and yellow offset segments indicate low fuel pressure.
Procedures:
Single Failure
Place L BOOST and R BOOST switches OFF.
NOTE
:
If helicopter is equipped with the Supplemental fuel system, refer to Section X,
“Operating Instructions: Supplemental Fuel System” for information regarding
fuel transfer with boost pumps off.
For operation with Secondary Fuels (Ref. Section II), continue flight and avoid
high ‘‘G’’ maneuvers.
Continue flight
NOTE
:
If flight is continued into low fuel conditions (fuel warning tick mark(s) on), it is
possible for an engine to flame out from fuel starvation with as much as 50 LBS
of fuel still being indicated on the fuel quantity display. Under this condition, the
indicated fuel is available for OEI flight using the remaining engine.
