MIL-STD-3009
4.2 System integration.
The design of the lighting equipment shall not interfere with the operation of the system
at night, with or without NVIS, or during the daytime.
4.2.1 Lighting provisions.
The design and location of the lighting equipment shall optimize visual performance and
minimize the effects on NVIS. The lights shall not cause direct or indirect glare or
interfere with the aircrew member’s interior or exterior unaided vision and with the
image intensification capabilities of the NVIS.
4.2.2 Compartment lighting.
Illuminance levels shall be as required by TABLE I, unless otherwise specified by the
acquiring activity. Chromaticity and spectral radiance limits shall be as specified in
TABLE II and TABLE III, respectively.
