(3) For the upper right and left position lights, mark a line 1/8 inch below and parallel to the center
line drawn in step 2. The line should extend from the light cover to the base of the lens. Place masking
tape on the upper part of the light assembly along the line drawn 1/8 inch below the center line. Note that
the masking tape will just cover the head of the Phillips screw on the light assembly covers.
(4) For the lower right and left position lights, measure and mark 1/8 inch above and parallel to the
center line mark on the lens. The line should extend from the light cover to the base of the lens. Place
masking tape on the lower part of the light assembly along the 1/8 inch line above the center line. Note
that the masking tape will just cover the head of the Phillips screw on the light assembly covers.
(5) Verify that slightly more than 1/2 of the top portions of the exposed upper position lights are
completely masked, and slightly more than 1/2 of the bottom parts of the lower position lights are
(8) To prevent overspray of the airframe CARC paint, cut a piece of stencil board, oil (NSN 9310-
00-160-7858) approximately 16 inches long by 11 inches wide and locate center point. Place the position
light template over the center point of the cut stencil board lengthwise and draw around the template.
Remove the template and, with a sharp instrument, cut out template area. The position light assembly
will be exposed to minimal overspray.
Roughing the exposed lens surfaces with either steel wool or sandpaper
prior to painting may make application easier and the paint adhere
(7) Paint the exposed area of the lenses using lacquer, olive drab, 16 oz. aerosol can (NSN 8010-
00-584-3149). Proceed until sufficient coats are applied to prevent any bleeding of light through the
painted area. Test the opacity of the painted area by turning on the position lights.
(8) A schematic of the above instructions may be found at figure 1.
b. Flight Procedures.
(1) All aircraft operations will be conducted in accordance with AR 95-1, AR 95-2 and AR 95-3;
applicable supplements to AR 95-1, AR 95-2 and AR 95-3; and Federal Aviation Administration (FAA)
The new masking scheme lights will alleviate NVG interference from the
aircraft's own position lights, but will not provide shielding from other
aircraft. Therefore, commanders must urge extreme caution when flying
multi-aircraft NVG operations, particularly when position lights are
required to be illuminated to meet regulations.
(2) No aircraft shall fly above 500 feet AGL with LIGHTS OUT/DIM, unless in a designated military
training area which meets the requirements of AR 95-2, paragraph 9-2. When in civil airspace,
compliance with FAA Exemption 3946E is required.
