EQUIPMENT LIMITATIONS:
An approved lighting system consists of two lights, one
located on each wingtip. The baseplate must be mounted
parallel to the vertical and horizontal centerlines of the aircraft
to project the patterns properly. A separate flasher assembly,
such as model 7145700, is required for each light assembly.
The Ground Recognition Light is a non-TSO function.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS:
The forward position light is designed with 4 Green LEDs or 5
Red LEDs. The tail position light is designed with 2 LEDs. The
ground recognition light is designed with 8 LEDs. The anticollision light is designed with 36 LEDs.
If any one bank of LEDs fails, the flasher module should be
checked. If module checks good, replace the lighthead. If any
one LED fails, the unit must be repaired or replaced. Inspect
the lens. Replace if there is excessive scratching, pitting,
discoloration or cracking.
Note: The anti-collision light will automatically shut-off after 910 flashes if a failure is detected.
INSTALLATION PROCEDURES:
The following information is to assist you in installing a
Whelen light system. The installation procedure described in
the following text will be confined to a single light installation,
but is identical for multiple light installations.
