After the nozzle is bonded to the aircraft, remove the dust cap from the nozzle and open the aircraft's fill
port.
Verify that all valves between the HEMTT tanker and the fuel nozzle are open.
Do not leave the nozzle at any time during refueling. Stop the flow of fuel if there is any emergency at
the refueling point. Three types of nozzles can be used for aircraft refueling. Use of the center-point (D-
1), CCR, and overwing (open-port) nozzle are described below.
- Center-point refueling nozzle operation. Remove the dust cover from the end of the nozzle body.
Grasp the handles and hold the nozzle in alignment with the aircraft refueling adapter. Press the
nozzle body against the adapter and turn handles to the right until the end of the nozzle mates and
locks to the aircraft refueling adapter. Rotate the control handle to the full OPEN position. The pilot
will signal when the tank is full. To disconnect, rotate the control lever to the full CLOSED position.
Grasp the handles and rotate the nozzle body to the left until it disconnects from the aircraft adapter.
- CCR nozzle. Mate the CCR nozzle to the fill port. Pull back on the control handle latch, and then
push the control handle up toward the aircraft into the FLOW position. If the aircraft is to be filled
completely, watch the back of the nozzle. A red indicator will pop out of the back of the nozzle when
the aircraft tank is full. Pull back on the flow control handle to move it into the NO FLOW position.
Unlatch the nozzle.
- Overwing (open-port) nozzle. Rapid refueling (hot) using the open-port nozzle is restricted to combat
or vital training (FM 10-67-1 (Concepts and Equipment of Petroleum Operation), Chapter 14). The
decision to use the open-port nozzle must be made by the commander. The open-port nozzle is
mated to the CCR nozzle. The end of the nozzle is placed in the aircraft fuel tank adapter. Set the
CCR nozzle to FLOW. Squeeze the control handle to dispense fuel. Watch the fill port when filling
the tank. As the tank nears full, ease up on the trigger and finish filling more slowly. When the tank is
full, release the trigger. Move the flow control handle on the CCR nozzle to the NO FLOW position.
Be sure that flow has stopped completely before removing the nozzle from the fill port.
Replace the cover of the aircraft fill port and put the dust cap back on the nozzle.
Unplug the nozzle bonding plug or release the bonding clip. Carry the nozzle back to the hanger. Do not
lay it or drag it across the ground.
Release the grounding cable clip from the aircraft.
Take the fire extinguisher back to a position near the nozzle hanger.
Have the aircrew and passengers reboard the aircraft.
Turn off the pump on the HEMTT tanker if no other aircraft is being refueled.
After receiving clearance, the aircraft lifts off.
Recirculation Mode. One recirculation nozzle is supplied with the HTARS. To recirculate the entire
system, the recirculation procedure must be performed for each refueling point. To perform recirculation,
ensure that personnel follow the procedures listed below:
Connect the recirculation nozzle to the refueling point (CCR nozzle).
Reposition hoses as required to reach the HEMTT tanker.
Connect the recirculation nozzle to the HEMTT tanker bottom loading receptacle A. Press the nozzle
body against the A receptacle and turn the handles to the right until the nozzle body locks firmly to the
receptacle.
Start and operate the HEMTT tanker IAW TM 9-2320-279-10-1.
Set the CCR nozzle to OPEN. Rotate the recirculation nozzle control lever to the full OPEN position.
If needed, fuel samples may be taken during the recirculation mode. The recirculation nozzle is equipped
with a hand-operated ball valve to allow sampling of the fuel entering the tanker. To take the fuel
sample, place the end of the tube in the sample container. Slowly move the control handle on the ball
valve to the open position. When sampling is complete, set the control handle on the ball valve to the
closed position.
When recirculation is complete, set the recirculation nozzle control handle to the closed position. Set the
CCR nozzle to the NO FLOW position.
Shut down the HEMTT tanker IAW TM 9-2320-279-10-1.
Disconnect the recirculation nozzle from the HEMTT tanker.
