CODE
Three digit number indicates a malfunction code.
DEL Pounds of fuel being transferred (25 lb increments).
SCH Pounds of fuel scheduled to be transferred. When scheduled point is reached, automatic
transfer is terminated. 2,500 lb automatically scheduled at power up.
9.3.1.6 Refuel SLEW Switch. The SLEW switch is a three position toggle switch which is springloaded
to the center position. If the refuel data display switch is in the SCH position, moving the switch
up increases pounds of fuel scheduled for transfer, and down decreases the fuel scheduled for transfer.
In SCH, the SLEW switch moves the selected indications as follows:
1. 0 to 100 lb, 75 lb/sec in 25 lb increments
2. 100 to 1,000 lb, 300 lb/sec in 100 lb increments
3. >1,000 lb, 600 lb/sec in 200 lb increments
9.3.1.7 BITE Flag Indicator. The BITE flag indicator indicates failures in the control panel assembly.
9.3.1.8 ALERT Indicators. There are two ALERT lights on the right side of the ARS panel.
LOW
RESV
A red warning light illuminates when the hydraulic reservoir level drops below ½ full
and begins flashing when the reservoir level drops below ¼ full.
DUMP ARS DUMP is not functional.

9.3.1.9 HOSE CUT/SAFE Switch. The HOSE CUT/SAFE switch is a two position switch springloaded
to the SAFE position and held in SAFE by a spring-loaded guard. The switch is wired through
the WonW interlock to prevent accidental activation on the deck.
SAFE Normal position.
CUT Refueling hose is cut and crimped. ARS is deactivated hydraulically and electrically.
Inflight, the switch must be held for several seconds.
9.3.1.10 Dimming (BRT/DIM) Switch. The BRT/DIM switch controls the intensity of the receiver
pilot advisory lights on the ARS tailcone and control panel displays. BRT is used for day operations,
and DIM is used for night operations.
9.3.1.11 Status Lights. There are four status lights on the ARS control panel.
STOW White light comes on when hose is approximately one foot from complete stowage. If
hose/drogue is not fully stowed, the indication is through a MASTER CAUTION and
aural tone, and the ARS DROGUE caution appears on the DDI.
RDY Amber light illuminates when the hose is fully deployed and automatic hose response is
established.
PRESS Red light illuminates when hydraulic pressure drops below 1,700 psi. Light goes out
when pressure exceeds 2,000 psi.
XFR Green light illuminates when a minimum of 20 gallons/min of fuel is being transferred
to the receiver.
9.3.1.12 TRANS Switch. The three position transfer switch is lever locked in the AUTO position and
controls fuel transfer to the receiver aircraft.
OVRD The ARS fuel pump is turned on regardless of hose position, fuel schedule, or fuel
remaining in the store. The OVRD position should only be used during emergency refueling
situations.
AUTO When connected to receiver aircraft, fuel flows when the following conditions are met:
· The hose is within the refueling range (approximately 5 to 20 feet of full trail),
· ARS (fuel is above 175 pounds) is not low on fuel; and,
· The scheduled amount of fuel is not exceeded.
OFF Turns the pump off regardless of hose position.
9.3.1.13 HOSE Switch. The three position switch controls the hose reel. The HOSE switch lever locks
in the RETR and EXT positions and is spring-loaded to EXT from the RESET position.
RETR The hose retracts or remains retracted.
A1-F18EA-NFM-000
III-9-11 ORIGINAL
EXT The hose extends or remains extended.
RESET Reset is used to establish a new reference pressure (after release to EXT) when airspeed
varies more than 10 KCAS from the last reference airspeed (either at extension
or at the time of the last RESET).
Do not select RESET when a receiver aircraft is plugged in. RESET
causes momentary loss of auto response and may damage receiver
aircraft.
Failure to reset hose reference pressure may result in hose auto retraction
if decelerating, or non-responsiveness if accelerating.
9.3.1.14 ARS DROGUE Caution. An ARS DROGUE caution on the DDI indicates that the ARS
PWR switch is OFF and the refueling drogue has not fully retracted.
9.3.2 ARS (Tanker) PROCEDURES.
9.3.2.1 Tanker Safety Precautions. Do not start the turbine, or extend or retract the drogue, over
populated areas or when other aircraft are close abeam or behind. Do not extend the drogue when an
ARS hydraulic leak is observed. Do not actuate the speed brake function during any part of the
refueling operation.
NOTE
When tanks 1 and 4 are empty, no more fuel can be transferred to the
ARS. With normal fuel transfer, this occurs at a normal aircraft fuel
