(a) Supplemental lighting is defined as additional interior lighting which may consist of LIP
lights (MIC Lights), finger lights, flashlights with filters and othersimilar devices. LIP/MIC lights and finger
lights do not fulfill the flashlight requirements of AR 95-1.
(b) New Items - PM soldier has developed , tested and approved the following new items:
(c) If the above are not available, the use of supplemental lighting which passes the evalua-
tion of para 81(2)(d) below is authorized. The specific lighting configurations authorized by unit command-
ers must be defined in unit SOPS. Additionally, unit commanders must ensure crew members receive
instruction in the use of authorized supplemental lighting including flashlight filters. As a minimum, the
following training must be addressed and documented:
and use of lighting.

Cautions/Warnings
2
degradation of the NVG performance caused by supplementary lighting.
3

knowledge of use.
4 Verify
NOTE
Flashlights with red or white lighting may not be used except for ground operations
or in the cargo compartment of UH-1, UH-60 or CH-47 aircraft, at the discretion of
the pilot in command (PC).
(d) Supplemental lighting degradation evaluation - A method for evaluating the effects of
supplemental lighting with ANVIS is as follows:
1 At night, in an aircraft located in an area of low ambient light (landing zone, etc), with
interior lighting set for NVG operations, and with ANVIS prepared for use, position a reflective material
(map sheet, note card, vinyl checklist, etc) at reading distance from your eyes (approximately 12 to 18
inches).
2 Shine the supplemental light onto the material. With the unaided eye, look at the re-
sultant reflection cast on the windscreen,
3 Observe the same reflection through the ANVIS. An acceptable supplemental light
source will allow NVG aided vision through the reflection, The reflection can even disappear.
4 If the reflection blocks ANVIS aided vision, this light source should be deemed unac-
ceptable.
Laser Pointers -
j.
(1) A study has been performed regarding the use of laser pointers in the cockpit of army aircraft.
Results indicate the use of visible laser pointers, or near-infrared (Near-IR) laser pointers greater than class
I, severely degrades the performance of NVGs and creates an eye hazard when used in the cockpit of army
helicopters,
(2) The AN/PA&4C infrared aiming light (NSN 5855-01-398-4315, LIN Number 34938,
5.00 ea) is a class I, Near-IR (830-860 nanometers) laser, which provides reasonable range performance
