EMPENNAGE
The empennage (Figure 1-18) consists of the
horizontal stabilizer, elevators with trim tabs,
vertical stabilizer, and a rudder with trim tabs.
The horizontal stabilizer is mounted high on
the vertical fin away from airflow disturbance
caused by the engine exhausts. Both the ver-
tical and horizontal stabilizers are all-metal,
using spars and stressed-skin construction. A
ram-air scoop is housed in the dorsal fin for-
ward of the vertical stabilizer.
AIRPLANE SYSTEMS
GENERAL
The following is a brief introduction to the
major airplane systems on the Hawker 800
XP. Detailed descriptions of these systems
are contained within the individual chapters
of the training manual.
ELECTRICAL POWER
SYSTEMS
The airplane electrical system is a 28-VDC
system which receives power from two starter-
generators connected through a split bus bar
system. An additional starter-generator is
available from the APU. Two main batteries
provide normal electrical system backup power
and a power source for internal engine start-
ing. An external power unit can be connected
via a three-pin plug to energize the bus bars
for servicing and engine starting. Two main in-
verters provide single-phase, 115-volt, 400-Hz
AC power. A standby inverter will supply es-
sential AC-operated systems in the event of
failure of both main inverters. Two trans-
formers provide 6-and 26-volt AC power. Two
engine-driven alternators provide indepen-
d e n t 2 0 8 - VAC p o w e r f o r w i n d s h i e l d ,
sidescreen, and stall vane heating. Two DC am-
meters, a DC voltmeter, and an AC voltmeter
are used to monitor the electrical system.
LIGHTING
The Hawker 800 XP has standard navigation,
beacon, strobe, landing, and taxi lights. A left
and right wing ice light is installed for wing ice
inspection. Interior lighting includes instru-
ment illumination and passenger cabin lamps,
step and vestibule lamps, passenger reading
lamps, toilet compartment lamps, and galley and
cabin notice lamps. Optional logo lamps are
available.
