LIGHTING SYSTEMS
Hawker 800XP Pro Line 21
Section III - SYSTEMS DESCRIPTION
STROBE LIGHTS (Figures 7 & 8)
Strobe lighting provides additional airplane identification to the standard airplane position light
presentations.
The strobe lighting system consists of three flashing white condenser discharge strobe lights, three
power supply units (PSU's 1, 2 and 3) and a STROBE light control switch. The control switch is located
on the flight compartment overhead roof panel forward extension labelled STROBE - OFF.
NOTE: Turn off strobe light when taxiing near other airplanes or when flying in fog or clouds.
Standard position lights must be used for all night operations.
A strobe light is installed in each wing tip, and one on the rear fuselage extremity. Each strobe light is
connected to its own power supply unit.
All three PSU's are installed in the passenger cabin left side below the passenger seating. In operation
the lights flash simultaneously at 60 flashes per minute (
±
5 FPM at the rated voltage).
LOGO LIGHTS (if installed Figures 7 & 8)
The vertical stabilizer logos are illuminated by lights mounted on the underside of the left and right
horizontal stabilizers. Both lights are controlled by a single LOGO-ICE-OFF switch located on the
EXTERIOR LIGHTS section of the flight compartment overhead roof panel forward extension.
BOARDING LIGHT (Figure 8)
The ground area and bottom steps of the main entry doorway are illuminated by the boarding light which
is also located with the wing ice inspection light in the left wing to fuselage front fairing assembly.
The boarding light is controlled by a switch on panel DA and a second switch on the forward vestibule
cabinet, labelled ROOF/STEP. The supply is taken from battery No. 1 so that it may be switched ON
without selection of the BATTERY master switch.
PULSE LIGHT
The pulse light is a four channel electrical switching device which connects to the external lighting
system of the airplane. The system operates by flashing the landing and nose taxi lights 45 times per
minute in a variety of patterns. Thus, creating an illusion of exaggerated motion that other pilots can
immediately recognize and avoid.
The pulse light may be utilized any time the pilot desires, although it is recommended that the landing
lights are switched to steady rate (full time) when the airplane is within 200 feet AGL at night. The pulse
light should not be operated in clouds at night or in close proximity of other airplanes on the ground,
due to possible pilot disorientation.
The pulse light is powered by 24/28 VDC with an amp load no greater than 25 AMPS per channel or
600 WATTS per channel.
