2Cautions W/ arnings associated with the lighting.
3_Demonstrate degradation ofthe NVG performance caused by supplementary lighting.
4_Verity knowledge of use .
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.
j. Laser Pointers -
(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 /PAQ -4C infrared aiming light (NSN 5855-01-398-4315 , LIN Number 34938 ,
-

$ 225.00 ea) is a class 1, Near -IR (830–860 nanometers) laser, which provides reasonable range performance
 TB 1-1500-346-20

with little to no degradation of the ANVIS performance when directed through the windscreen of helicopter
cockpits. This laser is deemed acceptable for use . Any class 1 Near - IR laser is acceptable for use in the
cockpits or cargo compartments of army helicopters.
( 3) Laser pointers other than class i Near - IR lasers may only be used in the cargo compartment
of UH- 1 , UH - 60 or CH -47 aircraft, at the discretion ofthe PC . The PC should include the use of laser pointers
in the crew and passenger briefing.

WARNING

Users should be aware that any laser can permanently or temporarily degrade the per
formanceofNVGs if used improperly. Any laser that is not a classi laser devicehas
the potential to cause direct permanent damage to the eye.
( 4 ) Unit commanders will (if applicable) develop SOPs regarding the safe use of laser pointers
during NVG helicopter missions. Guidance regarding hazards associated with tactical laser pointersis avail
able from the U.S. Army Center for Health Promotion and Preventive Medicine, DSN 584-3932 or (410)
671-3932. EMAIL is mchbdsl@aeha1.apgea.army.mil. General guidance regarding the safe use of lasers
is available in the following video tapes:
