Night Vision Modification
Ahlers can provide a wide range of NVIS Green A, Green B, and Intruder conversion methods, from fully internal to various external solutions including NVIS floodlights, post lights, eyebrow
assemblies, gooseneck utility lights, and internal and external NVIS filtering. We have full capability to modify annunciators, caution/warning panel, and internally lighted (MIL-P-7788)
Ahlers also offers a cost-effective NVIS "White" conversion.
In cases where full mil-spec conformance is not required, such as some civilian law enforcement and air-ambulance conversions, Ahlers offers a cost-effective NVIS "White" conversion. Filtered bezels are applied over all existing lighted instruments. The NVIS radiance of the existing lighting is reduced to the point that nighttime NVIS goggle use is not degraded, yet daytime perception of dial range marking colors remains natural to the unaided eye. In most installations, no modification is required to either the existing instrumentation or to the aircraft wiring, facilitating the local FAA approval process.
