GROUND SERVICING
Hawker 800XP Pro Line 21
Section VI - GROUND OPERATIONS
PRESSURE and GRAVITY FUELING
The airplane provides for pressure refueling through a coupling at the rear of the ventral tank
(Figure 6) or by gravity refueling through a filler cap in each outer wing (Figure 9) and the left side of
the ventral tank rear wall (Figure 10).
Refueling Control and Indication
All refuels are controlled from a refuel control panel, located on the right side of the forward vestibule,
adjacent to the forward bulkhead (Figure 6). The refuel control panel includes the tank refuel valve
switches and indicates the valves position and FULL condition of all tanks. The ventral tank contents
are displayed as either FULL, EMPTY or crosshatched as appropriate.
When the airplane 28 VDC busbars are energized, the refuel control panel electrical power is normally
supplied from the PE busbar circuit breakers and through the left weight-on-wheels switch. Both wing
tank fuel contents and the ventral tank contents are displayed on either the pilot’s or copilot’s CDU
engine page and the copilot’s MFD.
When the airplane has no external power, the APU is not running or the batteries are not switched ON,
the refuel control panel and the refuel/defuel circuits can be energized by the use of the POWER
switch on the refuel control panel.
(a) For Airplane Serial No. 258670 and subsequent or for airplanes with SB 24-3641 embodied:
The refuel control panel POWER switch also energizes the left CDU and two of the Data
Control Units (DCU) from the battery busbar which allows the fuel contents indications to be
displayed.
(b) For airplanes prior to Airplane Serial No. 258670 which do not have SB 24-3641 embodied:
Fuel contents indications will not be available because the right MFD and the left CDU are not
energized.
The refuel control panel is illuminated when either the door or vestibule ENTRY LIGHT is switched ON.
Parking the Airplane
If possible, park the airplane on level ground. If the ground slopes, park the airplane facing down the
slope.
Water Draining (Figures 6 & 8)
CAUTION:
INVESTIGATE ANY CONTAMINATION, OTHER THAN WATER, IN THE FOLLOWING
DRAINED SAMPLE.
Using the water drain tool, drain all water from tanks before and after refueling.
After refueling, delay the water drain check, if possible, for about 30 minutes. Free water readily
separates from the fuel but water in extremely fine droplets will remain suspended for at least 10
minutes. If the drain sample appears cloudy, it contains water and further time is required to allow this
water to settle.
NOTE: If the tank fuel temperature is below 0° C, the water drains may be frozen and ineffective with
water accumulating over successive flights. In these circumstances, it is essential that water
drain checks are complied with at the first opportunity when the tank temperature rises above
0° C.
